Each cabinet is available in single and dual driver configurations, with internal volume and tuning calculated independently for each setup. The Micro designation refers to the reduced external footprint, not a reduction in construction quality or acoustic accuracy. Every enclosure ships fully prepared — prewired from the terminal cup, polyfill pre-loaded, and stainless steel feet included for downfire positioning.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ai-block\"\u003e\n    \u003ch3\u003eStack Fab construction\u003c\/h3\u003e\n    \u003cp\u003eProline X Micro Resonix enclosures are built using Stack Fab construction, a layered fabrication method that bonds MDF panels under pressure to produce rigid cabinet walls and precise internal geometry. This eliminates the weak points associated with traditional butt joint construction and maintains cabinet integrity at the mechanical output limits of Resonix 10, 12, and 15-inch drivers. The double mounting face adds baffle rigidity directly at the driver cutout, reducing panel resonance during high-excursion operation. Stack Fab construction is used across the full Proline X lineup regardless of enclosure size or configuration.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ai-block\"\u003e\n    \u003ch3\u003eDriver mounting and hardware\u003c\/h3\u003e\n    \u003cp\u003eThe recessed woofer cutout on each Proline X Micro Resonix enclosure uses pre-installed threaded inserts with supplied 8\/32 machine screws for driver mounting. No separate hardware sourcing is required at install. Machine screws threading into steel inserts produce a consistent clamp load across the driver gasket, maintaining an airtight seal between the Resonix driver and the baffle on every installation. All mounting hardware ships with the enclosure and is sized for the specific driver cutout on each model.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ai-block\"\u003e\n    \u003ch3\u003eAdvanced Terminal Cup\u003c\/h3\u003e\n    \u003cp\u003eEach Proline X Micro Resonix enclosure uses an in-house Advanced Terminal Cup built from ABS and carbon fiber with stainless steel hardware. The terminal cup ships prewired, so the internal connection between the terminal and the driver is completed at the factory before the enclosure reaches the installer. Stainless steel hardware resists corrosion in vehicle environments where humidity and temperature cycles are constant. The ABS and carbon fiber construction keeps the terminal cup rigid under repeated use without cracking or deforming.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ai-block\"\u003e\n    \u003ch3\u003ePolyfill, prewiring, and downfire feet\u003c\/h3\u003e\n    \u003cp\u003eEvery Proline X Micro Resonix enclosure ships with polyfill pre-loaded, internal prewiring from the terminal cup completed, and stainless steel feet attached for downfire use. Polyfill increases the effective acoustic volume of a sealed enclosure without increasing its physical size, extending low-frequency output in a cabinet where internal volume is constrained by the compact footprint. The included feet elevate the enclosure off the vehicle floor, maintaining clearance for cone movement and port output in downfire configurations.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ai-block\"\u003e\n    \u003ch3\u003eHow Micro fits in the Proline X lineup\u003c\/h3\u003e\n    \u003cp\u003eProline X Micro Resonix enclosures share the same Stack Fab construction, Advanced Terminal Cup, threaded insert mounting system, and hardware spec as the full-size Proline X range. The Micro Series is the correct choice when install space is the primary constraint. When clearance is not a limitation, full-size Proline X enclosures provide greater internal volume supporting lower tuning frequencies and additional excursion headroom. Both series are available for Resonix 10-inch, 12-inch, and 15-inch drivers in single and dual configurations.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","products":[{"product_id":"proline-x-micro-series-12-sealed-enclosure-fits-resonix-gus-12","title":"Proline X Micro Series 12\" Sealed Enclosure - Fits ResoNix GUS 12","description":"\u003c!-- ============================================================\n     PROLINE X MICRO SERIES: ResoNix GUS-12\n     SEALED 12\" ENCLOSURE ONLY\n     Color system: Green (#16a34a primary)\n     ============================================================ --\u003e\n\n\u003cstyle\u003e\n  .ms-wrap * { box-sizing: border-box;

The GUS-12 has a published driver displacement of 0.047 cubic feet. Building a box to a gross internal volume of 0.75 cubic feet and then installing the driver would reduce the net acoustic airspace by 0.047, leaving the driver with only 0.703 cubic feet of effective volume and a Qtc slightly above target.\u003c\/p\u003e\n    \u003cp\u003eThe correct approach is to build the gross internal volume at 0.75 + 0.047 = 0.797 cubic feet, so that after driver displacement is subtracted, the driver sees exactly 0.75 cubic feet of net acoustic airspace. The M12-S GUS enclosure is built to a gross volume that delivers \u003cstrong\u003e0.80 cubic feet net\u003c\/strong\u003e after displacement, hitting ResoNix's recommended target accurately rather than approximately.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 1B: Why the External Dimensions Look Bigger Than They Should --\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 GUS enclosure. The math customers run looks like this: external dimensions of 26\" × 14.75\" × 6.75\" subtract 3\/4\" walls on all six sides, leaving an assumed internal cavity of 24.5\" × 13.25\" × 5.25\". That works out to 1,704 cubic inches, or roughly 0.99 cubic feet. The listed net volume is 0.80 cubic feet, a difference of nearly 0.20 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 GUS-12'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 0.047 cubic feet once installed.\u003c\/strong\u003e The basket, motor, and pole structure occupy roughly 81 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. This is the same level of engineering precision ResoNix applies to the GUS-12 driver itself, and it is why the 0.80 cubic foot figure is exact rather than approximate.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 2: The Driver --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003eWhy the GUS-12 Is Unlike Every Other Driver in This Series\u003c\/h3\u003e\n    \u003cp\u003eThe GUS-12 was engineered by ResoNix Sound Solutions, the same operation that independently Klippel-tests more car audio subwoofers than anyone else publishing data in the enthusiast market. The GUS-12 was built specifically to outperform every driver they had measured on BL linearity, Cms symmetry, inductance stability, and verified Xmax. The data is published and verifiable.\u003c\/p\u003e\n    \u003cp\u003eQts of 0.28 is the number that defines this driver's character in an enclosure. At 0.75 cubic feet sealed, the system Qtc targets 0.707, producing flat anechoic response with deep extension. Fs at 14.54 Hz means the driver's natural resonance is below the usable range of virtually any car audio system, which gives the sealed alignment maximum low-frequency extension capability before rolloff begins. The GUS-12 is not a plug-and-play daily build. It is an SQ and DSP-controlled install driver. The correct amplifier, active crossover, and shelf EQ will extract performance that no other shallow 12\" can match. The copper shorting rings, titanium voice coil former, and Nomex\/carbon fiber cone are engineering decisions that show up in the distortion measurements, not just the spec sheet.\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 front baffle is a double-layer stack-fab build: two CNC-cut Langboard Elite MDF panels bonded to 1.5 inches total.

The 6.75-inch total depth gives each side wall more inherent geometric rigidity than the ultra-shallow Wavtech builds in this series, and the Langboard Elite MDF used throughout has published 200 psi internal bond and 410,000 psi MOE specifications that hold up under sustained high-power use.\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\u003e0.80 cu ft: ResoNix Recommendation + Driver Displacement\u003c\/h4\u003e\n      \u003cdiv class=\"ms-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eResoNix recommends \u003cstrong\u003e0.75 cu ft\u003c\/strong\u003e net for 0.707 Qtc.

The GUS-15 has a published driver displacement of 0.072 cubic feet. Building to a gross volume of 1.35 cubic feet and installing the driver would leave only 1.278 cubic feet net — noticeably below the recommendation. The correct build target is 1.35 + 0.072 = 1.422 cubic feet gross, so that after driver displacement is subtracted the driver sees exactly 1.35 cubic feet of net acoustic airspace.\u003c\/p\u003e\n    \u003cp\u003eThis enclosure delivers \u003cstrong\u003e1.42 cubic feet net\u003c\/strong\u003e after displacement — matching ResoNix's acoustic volume recommendation accurately. The 1.42 figure is the net acoustic volume the driver sees, not the gross box volume before displacement is accounted for.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 2: Driver Context --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003eThe GUS-15 in a Sealed Enclosure — What the Numbers Mean\u003c\/h3\u003e\n    \u003cp\u003eThe GUS-15's published T\/S parameters (D4 variant) show Fs at 17.11 Hz and Qts at 0.34. At 1.35 cubic feet sealed, the system Qtc targets 0.707 — flat anechoic response extending well below 20 Hz. The 15\" cone area (Sd of 804.25 cm²) combined with 25.89mm of Klippel-verified one-way Xmax produces a displacement volume that translates directly to output. A 15\" driver at this Xmax in the correct sealed enclosure delivers low-frequency output that no shallow 12\" — including the GUS-12 — can match at the same power level.\u003c\/p\u003e\n    \u003cp\u003eLike the GUS-12, this is a DSP-controlled system driver. The 0.707 Qtc alignment produces a flat anechoic response that relies on cabin gain and active shelf EQ to build the final in-room curve. Without active equalization, the system will produce exceptional extension and very low distortion but will sound lean in the upper bass register. With a Goldhorn DSP or equivalent processor, the GUS-15 in this enclosure is the most capable shallow-mount bass system available at this depth.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 3: Construction --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003e1,500W RMS Demands a Different Level of Construction\u003c\/h3\u003e\n    \u003cp\u003eAt 1,500 watts RMS the GUS-15 generates more internal pressure than any other single driver in the Micro Series lineup by a significant margin. The front baffle is a double-layer stack-fab build — two CNC-cut Langboard Elite MDF panels bonded to 1.5 inches total thickness. The stack-fab assembly is further reinforced with dowels throughout the build, adding mechanical alignment and shear resistance at every panel joint beyond what dado joinery and adhesive alone provide.\u003c\/p\u003e\n    \u003cp\u003eThe 8.25-inch total depth gives panel walls more inherent geometric rigidity than the ultra-shallow builds in this series, but at 1,500 watts the increased excursion load and cone area of a 15\" driver means the structural demands on every panel and joint are correspondingly higher. Langboard Elite MDF at 200 psi internal bond and 410,000 psi MOE is the correct panel spec for this application — not because it is the cheapest option that passes, but because it is the named, documented spec that holds under sustained high-power use.\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\u003e1.42 cu ft Net — 1.35 Target + 0.072 Displacement\u003c\/h4\u003e\n      \u003cdiv class=\"ms-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eResoNix's 0.707 Qtc target is \u003cstrong\u003e1.35 cu ft net\u003c\/strong\u003e.

The GUS-12 has a published driver displacement of 0.047 cubic feet. Building each chamber to a gross volume of 0.75 cubic feet and then installing the driver would leave only 0.703 cubic feet of acoustic airspace — below the recommendation.

A single GUS-12 in the correct enclosure produces flat anechoic response extending well below 20 Hz — but at 800 watts RMS and a single 12\" cone, output in large vehicle cabins or competitive environments has a ceiling. Two GUS-12 drivers in isolated 0.75 cubic foot chambers double the cone displacement and the combined power handling to 1,600 watts RMS, while each driver still operates in exactly the enclosure volume it requires.\u003c\/p\u003e\n    \u003cp\u003eThe DSP requirement from the single GUS-12 build carries forward here. Both drivers have Qts of 0.28 — the system Qtc in each chamber targets 0.707, producing a flat anechoic response that requires active shelf EQ to build the in-cabin curve. Two drivers make that response louder and deeper. They do not change its character. A Goldhorn DSP or equivalent processor remains the correct companion for this system.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 3: Construction --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003e1,600W Combined — Construction Built to Match\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 GUS-10 is the front subwoofer platform on the enthusiast market right now — its 4.12\" mounting depth and compact sealed enclosure footprint put it in locations where nothing else with its distortion performance and extension capability can go.\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 — Stack Fab, Dado Joinery, 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 stack-fab assembly is further reinforced with dowels throughout, adding mechanical alignment and shear resistance at every panel joint beyond what dado joinery and adhesive alone provide. At 500 watts RMS on a 10\" driver with 18.37mm of one-way Xmax, the structural demands on the baffle are real — double-layer construction eliminates panel resonance at the source rather than allowing it to color the bass output.\u003c\/p\u003e\n    \u003cp\u003eEvery panel joint uses CNC-cut interlocking dado slots.

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. The 1.26 cu ft total listed is the gross volume across both chambers. The acoustic figure that matters for each driver is 0.60 cu ft per chamber.\u003c\/p\u003e\n    \u003cp\u003eThis is a cleaner acoustic alignment than the single M10-S GUS, which runs 0.603 cu ft net and sits fractionally below the 0.60 target.

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 anechorically but lean in the upper bass register without active shelf EQ.

The GUS-15 has a driver displacement of 0.072 cubic feet. Each chamber in the M15D-S GUS is built to 1.425 cubic feet gross — after the driver is installed, each GUS-15 sees 1.353 cubic feet of net acoustic airspace, hitting ResoNix's 1.35 cubic foot target precisely. Total gross enclosure volume is 2.85 cubic feet. The acoustically meaningful figure for each driver is 1.35 cubic feet per chamber.\u003c\/p\u003e\n    \u003cp\u003eThis is exactly double the volume of the single M15-S GUS enclosure, by design. The Proline X Micro Series approach to dual builds is to scale the volume linearly — the dual enclosure is built to deliver the same acoustic conditions per driver as the single. Both drivers in this enclosure load into identical acoustic environments, and both produce identical T\/S response curves.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 2: Why Dual GUS-15 --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003eTwo GUS-15 Drivers — 3,000W Combined, Maximum Shallow-Mount Output\u003c\/h3\u003e\n    \u003cp\u003eA single GUS-15 in the correct enclosure produces more output than any other shallow 15\" available — 1,500 watts RMS, 25.89mm of Klippel-verified one-way Xmax, and 804.25 cm² of effective cone area. Two GUS-15 drivers in isolated 1.35 cubic foot chambers double the cone displacement and raise the combined power handling to 3,000 watts RMS.

Both drivers have Fs of 17.11 Hz and Qts of 0.34 — the same 0.707 Qtc alignment, the same flat anechoic response, the same requirement for active shelf EQ to build the in-cabin curve.
