The SW and the A Series differ enough in what they want from a cabinet that we cut them separately, which is why you will see both listed here rather than one box claiming to cover both.\u003c\/p\u003e\n\n\u003ch3\u003eSW Series\u003c\/h3\u003e\n\u003cp\u003eMicro Series sealed cabinets for the SW10 at $269.99 and the SW12 at $299.99, plus a dual SW10 at $349.99.

Micro Series is our stack fabricated construction: layered CNC cut panels rather than dado joinery, with dowels between layers acting as tension reinforcement. It keeps the walls rigid at a reduced external footprint.\u003c\/p\u003e\n\n\u003cp\u003eAll four corners are radiused three inches top down, and the area behind the driver magnet is precision milled to recover internal volume and relieve backpressure against the voice coil.

Every layer is cut to the Arc Audio SW10's published sealed targets, with the baffle bored to the SW10's 9.1-inch cutout and 8\/32 threaded inserts set on the back face for tool-clean machine-screw mounting. The SW10 is a 2.4-inch shallow-mount driver built for tight, behind-the-seat and under-seat installs, and this enclosure is the matched airspace it was designed to live in.\u003c\/p\u003e\n \u003cp\u003eThe SW10 carries Arc Audio's published Thiele-Small data: Fs of 39 Hz, Qts of 0.634, Vas of 13.33 liters, and an EBP of 53, which places it firmly in sealed-enclosure territory.

That matters for two reasons. First, the net airspace stays true, because the motor is not stealing volume from inside the chamber. Second, the motor breathes free air on the front side of the baffle, so it is not trapped in a hot, sealed pocket. We do not mill a magnet-relief pocket the way we do on rear-motor drivers, because there is no rear motor to relieve. The chamber is clean, sealed, and built only for the cone.\u003c\/p\u003e\n \u003cdiv class=\"ms-highlight\"\u003e\n \u003cp\u003e\u003cstrong\u003eTrue net, not marketing net.\u003c\/strong\u003e Internal volume is calculated by summing each CNC-cut layer's opening.

Every layer is cut to the Arc Audio SW12's published sealed targets, with the baffle bored to the SW12's 11-inch cutout and 8\/32 threaded inserts set on the back face for tool-clean machine-screw mounting. The SW12 is a 2.4-inch shallow-mount driver built for deep, controlled bass in tight spaces, and this enclosure is the matched airspace it was designed to live in.\u003c\/p\u003e\n \u003cp\u003eThe SW12 carries Arc Audio's published Thiele-Small data: Fs of 33 Hz, Qts of 0.616, Vas of 33.73 liters, and an EBP of 45.9, which places it firmly in sealed-enclosure territory. We ran the alignment math on that data and built the box to land it where it belongs. The larger Vas means the SW12 wants more airspace than the SW10 to reach the same Qtc, which is why these boxes run deeper.\u003c\/p\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"ms-section\"\u003e\n \u003ch3\u003eOne Footprint, Three Net Volumes\u003c\/h3\u003e\n \u003cp\u003eAll three sizes share the same 26 by 14.75 inch face. Only the depth changes, so the box keeps the same mounting footprint whether you want the tightest response or the most extension.

A separate 4-foot kit is included so you can lift the enclosure off the floor when you mount it down-fire, which sets the gap the cone loads against, couples the bass into the chassis, and protects the driver face. Install the feet when you run it down-fire, leave them off when you do not. It also works front-fire as a secondary orientation if your space calls for it, so the same box covers both installs.\u003c\/p\u003e\n \u003cp\u003eThe SW12 helps here because its N42UH neodymium motor sits outside the sealed air volume. In a down-fire box that motor lives in the open cavity between the baffle and the floor rather than crammed inside a hot, sealed pocket, so it gets free airflow on every excursion. It also means the net airspace stays true, since the motor is not stealing volume from inside the chamber. We do not mill a magnet-relief pocket the way we do on rear-motor drivers, because there is no rear motor to relieve. The chamber is clean, sealed, and built only for the cone.\u003c\/p\u003e\n \u003cdiv class=\"ms-highlight\"\u003e\n \u003cp\u003e\u003cstrong\u003eTrue net, not marketing net.\u003c\/strong\u003e Internal volume is calculated by summing each CNC-cut layer's opening.

This enclosure is 1.0 cubic foot net, sitting between their minimum and their optimum rather than at it.\u003c\/p\u003e\n\u003cp\u003eThat is a deliberate choice, not a compromise on volume. A smaller sealed box raises system Qtc, which produces a more forward midbass and tighter transient control at the cost of the deepest anechoic extension. In a vehicle, where cabin gain already adds 6 to 12 dB below 80 Hz, the extension you lose on paper is largely restored in the listening position while the added control is audible immediately.\u003c\/p\u003e\n\u003cp\u003eIf you want the flattest possible alignment Arc specifies, you want a larger cabinet than a wedge this size can provide.

This enclosure delivers exactly 0.60 cubic feet of net acoustic airspace. At this volume the A10's system Qtc lands in the elevated range, producing a warm, upper-bass-forward response that suits daily-driver installs where impact and efficiency at listening volumes matter more than deep anechoic extension.\u003c\/p\u003e\n    \u003cp\u003eThe A10 has a mid-range Qts of approximately 0.51 and an Fs near 27 Hz. In the 0.60 cubic foot enclosure the system produces a naturally elevated Qtc, which translates to strong output in the 50 to 80 Hz range where most bass energy in music actually lives. This is the acoustic signature Arc Audio designed the A10 for. It is not an SQ competition driver, and it does not require DSP to sound good. It is a straightforward, honest shallow-mount 10\" that plays well when installed correctly.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 1B: Back-of-napkin math explanation --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003e\"If I Do the Math on the External Dimensions, the Volume Looks Too Big\"\u003c\/h3\u003e\n    \u003cp\u003eThis is the most common question we get on every Micro Series enclosure. The math customers run looks like this: external dimensions of 24\" × 14\" × 6\" subtract 3\/4\" walls on all six sides, leaving an assumed internal cavity of 22.5\" × 12.5\" × 4.5\". That works out to 1,266 cubic inches, or roughly 0.73 cubic feet. The listed net volume is 0.60 cubic feet, a difference of about 0.13 cu ft, which looks like the enclosure must be oversized by about 22%.\u003c\/p\u003e\n    \u003cp\u003eThat math assumes four things that are not true on a Proline X stack-fab enclosure:\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e1. The walls are not 3\/4\" on every side.\u003c\/strong\u003e The front baffle is a double-layer stack-fab build at 1.5 inches thick, twice the assumed wall thickness. That alone removes more internal depth than a 3\/4\" calculation accounts for.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e2. The enclosure is not a perfect rectangle.\u003c\/strong\u003e Viewed from above, all four corners are radiused at 3 inches. This is a deliberate design choice for two reasons: the rounded corners break up the parallel-wall geometry that creates internal standing waves, and they produce a finished shape that fits cleanly against vehicle interior surfaces without sharp corners catching on trim or upholstery. The 3\" radii remove measurable internal volume that an external-minus-walls calculation assumes is open airspace.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e3. The area directly behind the driver's magnet is precision-milled.\u003c\/strong\u003e This is a deliberate engineering step that serves two purposes. First, it allows us to make fine volume adjustments to hit the target airspace exactly. Second, and more importantly, it increases the open area immediately behind the driver's rear vent. The A10's pole vent is part of the driver's voice coil cooling system. Air flows through the vent during cone movement, carrying heat away from the voice coil former. If the area immediately behind the vent is restricted, backpressure builds against that airflow and voice coil cooling is compromised. Most enclosure manufacturers do not understand this airflow dynamic, and even fewer engineer around it. We do.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e4. The driver itself displaces internal airspace once installed.\u003c\/strong\u003e The basket, motor, and pole structure occupy roughly 60 to 70 cubic inches inside the chamber. This is not subtracted from a back-of-napkin external calculation, but it is subtracted from what the driver acoustically loads into.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eHow we actually calculate volume.\u003c\/strong\u003e Our engineering approach is built on precision, and it is different from how most enclosure manufacturers calculate airspace and different from the math any customer can do from external dimensions. A Proline X stack-fab enclosure is built from individually CNC-cut layers, each with its own machined opening. We calculate the precise internal volume of every layer's opening, then sum those layer-by-layer volumes to arrive at the actual net airspace inside the assembled enclosure. No one else in this industry calculates net volume this way. It is the only method that produces a genuinely accurate account of the airspace a driver sees once the enclosure is built. The 0.60 cubic foot figure is exact, not approximate.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 2: Driver character --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003eThe A10 in a 0.60 cu ft Sealed Box: What It Sounds Like\u003c\/h3\u003e\n    \u003cp\u003eThe Arc Audio A10 is a daily-driver shallow subwoofer. It is not marketed as an SQ competition driver, and it is not engineered to compete in that category. Its Qts of approximately 0.51 sits between the low-Qts SQ drivers (like the ResoNix GUS series) and the high-Qts warm-bass drivers (like the Alpine RS-W10D4). In a 0.60 cubic foot sealed box the A10 produces the tonal balance most listeners recognize as \"good bass\" in a daily driver: strong output in the upper bass range, moderate extension into the low bass, and no need for a DSP to produce a pleasing in-cabin response.\u003c\/p\u003e\n    \u003cp\u003eArc Audio has been building the A-Series since 2020, and it has developed a reputation as one of the more musical shallow-mount 10\" drivers available at its price point. In the correct enclosure, running clean unclipped power in the 200 to 250 watt RMS range, it delivers exactly the daily-driver experience it was designed for.

The stack-fab assembly is further reinforced with dowels throughout, adding between-layer tension reinforcement that locks the panel stack against shear movement under sustained operation. At 250 watts RMS the mechanical load is moderate, but the construction standard is the same across the entire Micro Series lineup because the goal is to build an enclosure that holds its acoustic seal for the life of the vehicle, not just the first year.\u003c\/p\u003e\n    \u003cp\u003eThe stack-fab construction itself does the joining: every CNC-cut layer interlocks with the layers above and below it, eliminating single-layer butt joints entirely. The 6-inch total depth gives the enclosure side walls adequate geometric rigidity for the load, and Langboard Elite MDF at 200 psi internal bond and 410,000 psi MOE is the correct panel spec for a driver in this power class.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- WHY CARDS --\u003e\n  \u003cdiv class=\"ms-card-grid\"\u003e\n\n    \u003cdiv class=\"ms-card\"\u003e\n      \u003cspan class=\"ms-card-label\"\u003eVolume\u003c\/span\u003e\n      \u003ch4\u003e0.60 cu ft, Exactly Arc's Published Optimum\u003c\/h4\u003e\n      \u003cdiv class=\"ms-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eArc Audio publishes \u003cstrong\u003e0.60 cu ft as the optimum sealed volume\u003c\/strong\u003e for the A10.

This enclosure delivers exactly 0.60 cubic feet of net acoustic airspace.

At this volume the system Qtc lands in the elevated range, producing strong output between 50 and 80 Hz where most bass energy in music actually sits.

External dimensions of 24 by 14 by 6 inches, minus 3\/4 inch walls on all six sides, appears to leave roughly 0.73 cubic feet. The listed figure is 0.60. That looks like a 22 percent discrepancy.\u003c\/p\u003e\n\u003cp\u003eThe calculation assumes four things that are not true here. \u003cstrong\u003eThe baffle is 1.5 inches, not 0.75\u003c\/strong\u003e, because it is a double layer stack fab build. \u003cstrong\u003eAll four corners are radiused three inches top down\u003c\/strong\u003e, which removes measurable volume that a rectangular calculation assumes is open airspace. \u003cstrong\u003eThe area behind the driver magnet is precision milled\u003c\/strong\u003e, both to trim volume to target and to increase open area behind the pole vent so voice coil cooling airflow is not restricted. And \u003cstrong\u003ethe driver itself displaces airspace\u003c\/strong\u003e once installed, which an external calculation never accounts for.\u003c\/p\u003e\n\u003cp\u003eWe calculate net volume by summing the internal volume of every CNC cut layer's opening. That is the only method that gives an accurate figure for what the driver actually loads into. The 0.60 is exact, not approximate.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"ml-section\"\u003e\n\u003ch3\u003eShallow Is a Solution to a Constraint\u003c\/h3\u003e\n\u003cp\u003eThe A10 exists because behind seat and under seat spaces have a depth the vehicle decides and you do not.

This enclosure delivers exactly 1.0 cubic foot of net acoustic airspace. At this volume the A12 produces the balanced tonal signature Arc Audio designed the A-Series for: strong upper-bass presence, moderate deep-bass extension, and the kind of daily-driver character that sounds good at real-world listening levels without requiring DSP correction.\u003c\/p\u003e\n    \u003cp\u003eThe A12 uses a 3-inch voice coil (versus the A10's 2.5-inch) for higher thermal capacity, and its larger cone area produces roughly 3 dB more low-frequency output than the A10 in equivalent enclosure volumes.

The math customers run looks like this: external dimensions of 28.5\" × 14.75\" × 7.5\" subtract 3\/4\" walls on all six sides, leaving an assumed internal cavity of 27\" × 13.25\" × 6\". That works out to 2,146 cubic inches, or roughly 1.24 cubic feet. The listed net volume is 1.0 cubic foot, a difference of nearly 0.24 cu ft, which looks like the enclosure must be oversized by about 24%.\u003c\/p\u003e\n    \u003cp\u003eThat math assumes four things that are not true on a Proline X stack-fab enclosure:\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e1. The walls are not 3\/4\" on every side.\u003c\/strong\u003e The front baffle is a double-layer stack-fab build at 1.5 inches thick, twice the assumed wall thickness. That alone removes more internal depth than a 3\/4\" calculation accounts for.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e2. The enclosure is not a perfect rectangle.\u003c\/strong\u003e Viewed from above, all four corners are radiused at 3 inches. This is a deliberate design choice for two reasons: the rounded corners break up the parallel-wall geometry that creates internal standing waves, and they produce a finished shape that fits cleanly against vehicle interior surfaces without sharp corners catching on trim or upholstery. The 3\" radii remove measurable internal volume that an external-minus-walls calculation assumes is open airspace.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e3. The area directly behind the driver's magnet is precision-milled.\u003c\/strong\u003e This is a deliberate engineering step that serves two purposes. First, it allows us to make fine volume adjustments to hit the target airspace exactly. Second, and more importantly, it increases the open area immediately behind the driver's rear vent. The A12's pole vent is part of the driver's voice coil cooling system. Air flows through the vent during cone movement, carrying heat away from the voice coil former. If the area immediately behind the vent is restricted, backpressure builds against that airflow and voice coil cooling is compromised. Most enclosure manufacturers do not understand this airflow dynamic, and even fewer engineer around it. We do.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e4. The driver itself displaces internal airspace once installed.\u003c\/strong\u003e The basket, motor, and pole structure occupy meaningful volume inside the chamber. This is not subtracted from a back-of-napkin external calculation, but it is subtracted from what the driver acoustically loads into.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eHow we actually calculate volume.\u003c\/strong\u003e Our engineering approach is built on precision, and it is different from how most enclosure manufacturers calculate airspace and different from the math any customer can do from external dimensions. A Proline X stack-fab enclosure is built from individually CNC-cut layers, each with its own machined opening. We calculate the precise internal volume of every layer's opening, then sum those layer-by-layer volumes to arrive at the actual net airspace inside the assembled enclosure. No one else in this industry calculates net volume this way. It is the only method that produces a genuinely accurate account of the airspace a driver sees once the enclosure is built. The 1.0 cubic foot figure is exact, not approximate.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 2: Driver character --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003eThe A12 in a 1.0 cu ft Sealed Box: What It Sounds Like\u003c\/h3\u003e\n    \u003cp\u003eThe Arc Audio A12 is a daily-driver shallow subwoofer built on the same A-Series platform as the A10, scaled up to a 12-inch cone with a 3-inch voice coil. It is not marketed as an SQ competition driver, and it is not engineered to compete in that category. In the 1.0 cubic foot sealed target, the A12 produces the tonal balance most listeners recognize as \"good bass\" in a daily driver: strong output in the upper-bass range where most bass energy in music lives, moderate extension into the low bass, and no need for DSP to produce a pleasing in-cabin response.\u003c\/p\u003e\n    \u003cp\u003eThe 12-inch cone gives the A12 about 44% more cone area than the A10, which translates to roughly 3 dB more low-frequency output in equivalent enclosure volumes. The 3-inch voice coil provides higher thermal capacity than the A10's 2.5-inch coil, letting the A12 run its 300 watts RMS reliably in daily-driver use. Running clean unclipped power in the 250 to 300 watt RMS range in this enclosure, the A12 delivers exactly the daily-driver experience Arc Audio designed it for.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 3: Construction --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003e1.5\" Double-Layer Baffle.

The stack-fab assembly is further reinforced with dowels throughout, adding between-layer tension reinforcement that locks the panel stack against shear movement under sustained operation. At 300 watts RMS the mechanical load is moderate, but the construction standard is the same across the entire Micro Series lineup because the goal is to build an enclosure that holds its acoustic seal for the life of the vehicle, not just the first year.\u003c\/p\u003e\n    \u003cp\u003eThe stack-fab construction itself does the joining: every CNC-cut layer interlocks with the layers above and below it, eliminating single-layer butt joints entirely.

The M10D-S ARC SW10 is a common-chamber design: both SW10 subwoofers share a single 1.2 cubic foot internal airspace with no dividing wall between them. Two drivers sharing 1.2 cubic feet of airspace load acoustically equivalent to a single SW10 in 0.60 cubic feet of airspace. The ratio of cone displacement to airspace stays the same, and Arc Audio's 0.60 cubic foot per-driver target is met precisely.\u003c\/p\u003e\n    \u003cp\u003eCommon-chamber dual designs are the correct engineering approach when both drivers are receiving the same signal and moving in phase. Physically dividing the enclosure into two isolated 0.60 cubic foot chambers would produce identical acoustic behavior at higher construction complexity and lower structural rigidity across the enclosure as a whole. The common chamber is simpler, stronger, and acoustically equivalent. Structural bracing is integrated into the panel layering rather than requiring a full dividing wall.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 1B: Back-of-napkin math explanation --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003e\"If I Do the Math on the External Dimensions, the Volume Looks Too Big\"\u003c\/h3\u003e\n    \u003cp\u003eThis is the most common question we get on every Micro Series enclosure. The math customers run looks like this: external dimensions of 34\" × 14.5\" × 7.5\" subtract 3\/4\" walls on all six sides, leaving an assumed internal cavity of 32.5\" × 13\" × 6\". That works out to 2,535 cubic inches, or roughly 1.47 cubic feet. The listed net volume is 1.2 cubic feet, a difference of about 0.27 cu ft, which looks like the enclosure must be oversized by about 22%.\u003c\/p\u003e\n    \u003cp\u003eThat math assumes four things that are not true on a Proline X stack-fab enclosure:\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e1. The walls are not 3\/4\" on every side.\u003c\/strong\u003e The front baffle is a double-layer stack-fab build at 1.5 inches thick, twice the assumed wall thickness. That alone removes more internal depth than a 3\/4\" calculation accounts for.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e2. The enclosure is not a perfect rectangle.\u003c\/strong\u003e Viewed from above, all four corners are radiused at 3 inches. This is a deliberate design choice for two reasons: the rounded corners break up the parallel-wall geometry that creates internal standing waves, and they produce a finished shape that fits cleanly against vehicle interior surfaces without sharp corners catching on trim or upholstery. The 3\" radii remove measurable internal volume that an external-minus-walls calculation assumes is open airspace.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e3. The area directly behind each driver's magnet is precision-milled.\u003c\/strong\u003e This is a deliberate engineering step that serves two purposes. First, it allows us to make fine volume adjustments to hit the target airspace exactly. Second, and more importantly, it increases the open area immediately behind each driver's rear vent. The SW10's pole vent is part of the driver's voice coil cooling system. Air flows through the vent during cone movement, carrying heat away from the voice coil former. If the area immediately behind the vent is restricted, backpressure builds against that airflow and voice coil cooling is compromised. Most enclosure manufacturers do not understand this airflow dynamic, and even fewer engineer around it. We do.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003e4. The drivers themselves displace internal airspace once installed.\u003c\/strong\u003e Each SW10's basket, motor, and pole structure occupies meaningful volume inside the chamber. Two SW10s displace twice as much as one. This is not subtracted from a back-of-napkin external calculation, but it is subtracted from what the drivers acoustically load into.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eHow we actually calculate volume.\u003c\/strong\u003e Our engineering approach is built on precision, and it is different from how most enclosure manufacturers calculate airspace and different from the math any customer can do from external dimensions. A Proline X stack-fab enclosure is built from individually CNC-cut layers, each with its own machined opening. We calculate the precise internal volume of every layer's opening, then sum those layer-by-layer volumes to arrive at the actual net airspace inside the assembled enclosure. No one else in this industry calculates net volume this way. It is the only method that produces a genuinely accurate account of the airspace the drivers see once the enclosure is built. The 1.2 cubic foot figure is exact, not approximate.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 2: Driver character and dual SW10 output --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003eThe SW10 in a 0.60 cu ft Per-Driver Sealed Alignment: What It Sounds Like\u003c\/h3\u003e\n    \u003cp\u003eThe Arc Audio SW10 is Arc's SW Series shallow SQ subwoofer, engineered for sound quality applications where enclosure depth is limited. It uses a front-mounted N42UH neodymium motor with a CNC-machined vented iron motor cap, a raised-cup reinforced cellulose fiber cone with hydrophobic coating, a low-shore butyl rubber surround, a Nomex\/cotton spider, a stage-baked tempered aluminum voice coil, and 14.7mm of one-way linear excursion. The 2.4-inch mounting depth is the SW Series shallow-mount signature: a real SQ driver that fits where other SQ drivers cannot.\u003c\/p\u003e\n    \u003cp\u003eTwo SW10s in this common-chamber enclosure produce roughly 3 dB more low-frequency output than a single SW10 at equivalent power, and combined thermal capacity is 700 watts RMS. The dual configuration is the correct choice when a single SW10 is not enough output for the cabin size, or when the wider footprint distributes bass energy across a broader listening zone (particularly effective in trucks where the enclosure spans the full cab floor width behind the seats).\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 3: Construction --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003e1.5\" Double-Layer Baffle. Common Chamber. Integrated Bracing.\u003c\/h3\u003e\n    \u003cp\u003eThe front baffle is a double-layer stack-fab build: two CNC-cut Langboard Elite MDF panels bonded to 1.5 inches total. Both SW10 mounting positions are cut from the same continuous baffle for consistent alignment. The stack-fab assembly is reinforced with dowels throughout, adding between-layer tension reinforcement that locks the panel stack against shear movement.\u003c\/p\u003e\n    \u003cp\u003eThe common-chamber approach on this dual build integrates structural bracing directly into the panel layering rather than requiring a full dividing wall between drivers. The CNC-cut layer geometry provides internal rigidity at the correct locations to resist panel flex under combined driver loading, without segmenting the acoustic volume. The result is a stronger enclosure at lower material weight, with acoustic conditions that match Arc Audio's per-driver optimum for both SW10s simultaneously.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- WHY CARDS --\u003e\n  \u003cdiv class=\"ms-card-grid\"\u003e\n\n    \u003cdiv class=\"ms-card\"\u003e\n      \u003cspan class=\"ms-card-label\"\u003eVolume\u003c\/span\u003e\n      \u003ch4\u003e1.2 cu ft Common Chamber, 0.60 cu ft Per Driver Equivalent\u003c\/h4\u003e\n      \u003cdiv class=\"ms-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eBoth SW10s share a \u003cstrong\u003e1.2 cu ft common chamber\u003c\/strong\u003e.
