At \u003cstrong\u003e1.5 ft³ net\u003c\/strong\u003e in a shared air space with heavy internal bracing, and sealed alignment, this enclosure delivers controlled, accurate bass across a wider presentation than any single 10\" can produce.

The M10D-S WAV delivers 0.40 cubic feet of net volume per chamber. That figure already accounts for driver displacement.

The GUS-10 has a driver displacement of 0.031 cubic feet. Each chamber in the M10D-S GUS is built to 0.63 cubic feet gross. After the driver is installed, each GUS-10 sees 0.599 cubic feet of net acoustic airspace, hitting ResoNix's 0.60 cubic foot target to within rounding.

A single GUS-10 delivers all of that from one driver. Two GUS-10 drivers in isolated 0.60 cubic foot chambers double the cone displacement, the variable that determines how much air is moved at any given frequency, and raise the combined power handling to 1,000 watts RMS.\u003c\/p\u003e\n \u003cp\u003eThe acoustic character does not change between the single and dual builds. Both GUS-10 drivers have Qts of 0.35 and Fs of 16.91 Hz. Each loads into a 0.707 Qtc sealed alignment. The response is flat and extended with deep low-frequency reach. The dual build makes the response louder and deeper: more cone displacement into the same acoustic loading per driver produces roughly 3 dB more low-frequency output.\u003c\/p\u003e\n \u003c\/div\u003e\n\n \u003c!-- SECTION 3: Construction --\u003e\n \u003cdiv class=\"ms-section\"\u003e\n \u003ch3\u003e1,000W Combined, Double-Layer Baffle, Dowel Reinforced\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.

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.

0.61, which means it cannot reach a textbook 0.707 Qtc in any enclosure that fits in a vehicle. You would need 3.41 cu ft per driver. At 0.60 cu ft this alignment lands at Qtc 1.048, which puts a roughly 1.5 dB lift around 47 Hz and an anechoic F3 of 36.4 Hz. That is an impact alignment, not a flat one. Loaded into a trunk or cargo floor and firing down, cabin gain fills in below the knee and the result is a punchy, high output system. If you want a flat sealed alignment above all else, this is not the driver or the enclosure for it.\u003c\/p\u003e\u003c\/div\u003e\n\u003cp\u003eRun your own numbers with the \u003ca href=\"\/pages\/sealed-box-calculator\"\u003eSealed Box Calculator\u003c\/a\u003e.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"podf-section\"\u003e\n\u003cp\u003eFull dimensions, cutout, mounting depth, and hardware details are listed under the \u003cstrong\u003eEnclosures\u003c\/strong\u003e tab.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"podf-cta\"\u003e\n\u003ch3\u003eCut for the GT2 2010.

Both baffles are bored to Kicker's \u003cstrong\u003e9.125 inch mounting hole\u003c\/strong\u003e specification, and the internal height is set by the driver's \u003cstrong\u003e3.4375 inch top mount depth\u003c\/strong\u003e. The footprint is the same 30 by 15 inches as the single driver Down Fire, standing 10.125 inches tall. It takes up no more floor area than the single, it simply stands taller, so measure vertical clearance before you order. This is a cargo floor or rear wall build, not an under seat build.\u003c\/p\u003e\n\u003cp\u003eEach 48CWRT104 is a dual 4 ohm shallow mount rated 400 watts RMS. It uses an injection molded polypropylene cone, a Santoprene rubber surround with Kicker's red double stitching, the SoloKon integrated cone to backplate design, and Forced-Air Cooling that runs the motor roughly 20 percent cooler. The cone and surround are UV resistant, which is why this driver turns up in UTV and open cab builds as often as it does in trucks.\u003c\/p\u003e\n\u003cp\u003eThe Thiele-Small data this enclosure is cut from comes from \u003cstrong\u003eKlippel measurement\u003c\/strong\u003e rather than a datasheet estimate: Fs 32.3 Hz, Qts 0.618, Vas 27.80 liters, Bl 19.158 Tm, Mms 150.85 g, Sd 349.67 cm², and 13.35mm of linear excursion. A 32.3 Hz free air resonance on a shallow 10 is genuinely low, and it is what lets a thin driver produce real low frequency output.

That match is deliberate. You are not getting a different sound, you are getting roughly 6 dB more of the same one.\u003c\/p\u003e\n\u003cdiv class=\"df-highlight\"\u003e\u003cp\u003e\u003cstrong\u003eTrue net, not marketing net.\u003c\/strong\u003e Internal volume is calculated from the machined cavity dimensions and the driver's published displacement, not estimated from external dimensions minus wall thickness.\u003c\/p\u003e\u003c\/div\u003e\n\u003cp\u003eKicker's published sealed range runs 0.4 to 1.25 cubic feet per driver, and the alignment does improve slightly with more air. On this footprint, though, every additional 0.1 cubic feet per chamber adds roughly an inch of cabinet height.

The motor is a high-grade neodymium design driving a 4 inch high-temperature USA-wound voice coil, with Alpine's DD Linear dual magnetic gap for low distortion at high excursion, a vented coil former, and motor cooling fins. Frames are die-cast aluminum with black anodized threaded rear mounting frames and aluminum dust caps.\u003c\/p\u003e\n\u003cp\u003eNeodymium is what keeps a dual cabinet this short.

The per chamber figure is the number that matters acoustically: each driver only ever sees its own 0.50, which is Alpine's small-volume sealed target exactly, where Alpine publishes an \u003cstrong\u003eF3 of 32 Hz\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cdiv class=\"df-highlight\"\u003e\u003cp\u003e\u003cstrong\u003eTrue net, not marketing net.\u003c\/strong\u003e Internal volume is calculated from the machined cavity dimensions and the driver's published displacement, not estimated from external dimensions minus wall thickness.\u003c\/p\u003e\u003c\/div\u003e\n\u003cp\u003eBoth coil variants are worth stating because the enclosure ships without drivers.

A Qts of 0.624 is a healthy, moderate figure, so this driver reaches a properly controlled alignment rather than sitting underdamped regardless of box size. Arc's published range runs 0.4 gross minimum to 0.9 gross maximum per driver.\u003c\/p\u003e\n\u003cp\u003eThe tradeoff is worth stating plainly. A 39.3 Hz free air resonance and a 12.96 liter Vas are the cost of a 2.4 inch motor, so F3 sits in the mid 40s rather than the 30s.

No gross versus net convention closes a gap that size, so we publish the figure that follows from the driver data. Free-air resonance is 48.0 Hz on the D2 and 48.5 Hz on the D4, which is why F3 lands in the low 50s in any sealed volume.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eDown Fire Construction\u003c\/h3\u003e\n\u003cp\u003eCut with V-groove and dado joinery on our ShopSabre routers from Langboard Elite 3\/4 inch MDF, a dense 48.5 lb\/ft³ board with a 200 psi internal bond and 410,000 psi MOE.

Flat honeycomb Hexatech aluminium cones, double magnet EVC motors, and 129.5mm voice coils, 5.1 inches, wound in four layers of carbon on aluminium formers. Most shallow 10s run a 2 to 2.5 inch coil, and that surface area difference is why these take 700 watts apiece continuously.

Each driver's compression phase becomes the pressure environment the other is working against, which smears transient response and blurs the alignment either would have on its own. A full divider removes that entirely. One shared side mounted terminal cup feeds both driver positions in parallel, so the cabinet stays a single connection point.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eNet Volume, Not Gross\u003c\/h3\u003e\n\u003cp\u003eEach chamber is built at \u003cstrong\u003e0.50 cubic feet net per driver\u003c\/strong\u003e, \u003cstrong\u003e1.00 cubic foot net total\u003c\/strong\u003e, out of 1.14 gross.

That sits above the 0.707 maximally flat reference, which trades a little damping for a slightly firmer corner. It is also closer to Prodigy's own 0.65 cubic foot sealed recommendation than the single driver cabinet manages, since halving the chamber width brings the volume back down toward their target rather than away from it. Firing down into the floor, the sealed rolloff meets rising cabin gain below 60 Hz, so in-car response extends well below the anechoic figure.\u003c\/p\u003e\n\u003cp\u003eHere is the part worth knowing. The 5.625 inch mounting depth forces a minimum internal height of 5 inches no matter how the cabinet is divided, because depth is a vertical measurement and the divider runs vertically too.

Splitting the width in two brings each chamber closer to the 0.625 cubic feet JL Audio recommends than the single driver cabinet can manage, but 0.849 sits above the 0.707 maximally flat reference, so there is more lift near the corner than the single cabinet shows at Qtc 0.693. Be straight about the tradeoff: the single is the better aligned product and this one is the output product. Both are legitimate, they simply answer different questions. Firing down into the floor, the sealed rolloff meets rising cabin gain below 60 Hz either way.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eTwo Chambers, Not One\u003c\/h3\u003e\n\u003cp\u003eThis enclosure follows the Proline X standing design rule for dual sealed builds: \u003cstrong\u003etwo fully separate chambers\u003c\/strong\u003e split by a bonded full-height 3\/4 inch MDF divider, so each driver gets its own dedicated airspace and its own polyfill.

A full divider removes the interaction completely.\u003c\/p\u003e\n\u003cp\u003eThe divider runs vertically, so splitting the cabinet does not change the depth requirement at all. Minimum internal height after the flush recess baffle layer and the milled magnet relief is 5.3125 inches; we build to \u003cstrong\u003e5.75 inches internal\u003c\/strong\u003e, an 8 inch external cabinet, which leaves 0.945 inch of clearance behind each motor instead of the half inch minimum.

With 11mm of Xmax and 600 watts per driver on tap, there is headroom behind it.\u003c\/p\u003e\n\u003cp\u003eProdigy publishes a sealed range of 0.75 to 1.0 cubic feet, so this sits well under their figure.

This cabinet fires down into the floor, so the sealed rolloff meets rising cabin gain below 60 Hz and in-car response extends well below the anechoic number.
