Proline X Micro Series Dual 10" Sealed Enclosure - Fits ResoNix GUS 10
Dual GUS-10. 1.26 cu ft Total.
0.60 cu ft Acoustic Per Driver — ResoNix's Optimum.
Two ResoNix GUS-10 drivers. Two acoustically isolated sealed chambers. Each chamber holds 0.63 cubic feet gross — which after the GUS-10's 0.031 cubic foot driver displacement delivers 0.599 cubic feet of net acoustic airspace per driver. ResoNix's published 0.707 Qtc target is 0.60 cubic feet. The M10D-S GUS hits that target precisely in 8.25 inches of total depth. 1,000 watts RMS combined.
0.63 cu ft Per Chamber — 0.60 cu ft Acoustic After Displacement
ResoNix publishes a 0.707 Qtc target of 0.60 cubic feet of net acoustic airspace for the GUS-10. 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.
This 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. The dual build, with its larger overall enclosure volume to work with, hits the per-chamber target more precisely. Both drivers load into identical acoustic conditions.
Two GUS-10 Drivers — Double the Displacement, Same Alignment
The GUS-10's case as the front sub platform rests on three things: 4.12 inches of mounting depth, Klippel-verified 18.37mm one-way Xmax, and a flat 0.707 Qtc sealed alignment that extends well below 20 Hz. 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.
The 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. A Goldhorn DSP or equivalent processor remains the correct companion for this system — the dual build makes the response louder and deeper, not warmer or more forgiving without EQ.
1,000W Combined — Double-Layer Baffle, Dado Joinery, Dowel Reinforced
The front baffle is a double-layer stack-fab build — two CNC-cut Langboard Elite MDF panels bonded to 1.5 inches total. At 1,000 watts RMS combined across two high-excursion 10" drivers, baffle resonance is a structural concern, not a theoretical one. The stack-fab assembly is reinforced with dowels throughout the build, adding mechanical alignment and shear resistance at every panel joint beyond what dado joinery and adhesive alone provide.
The chamber divider is CNC-cut and dado-jointed to the same standard as every exterior panel. It is a structural element — both chambers maintain their acoustic isolation and geometric integrity under sustained 1,000-watt operation.
Impedance Wiring — Know Before You Order
0.60 cu ft Acoustic Per Driver — ResoNix's 0.707 Qtc Target
Each chamber is built to 0.63 cu ft gross. After the GUS-10's 0.031 cu ft displacement, each driver sees 0.599 cu ft net acoustic airspace — essentially exactly ResoNix's published 0.60 cu ft optimum. Both chambers are identical. Both drivers load correctly.
1,000W RMS Combined — Dual Klippel-Verified Xmax
Two GUS-10 drivers at 500W RMS each with 18.37mm Klippel-verified Xmax per driver. Combined cone displacement doubles the output potential of the single GUS-10 build — particularly below 30 Hz where cone area and linear excursion are the dominant output variables.
Dual Chamber — CNC Divider, Dado Jointed, Independently Sealed
A CNC-cut, dado-jointed chamber divider separates both driver volumes completely. Neither GUS-10 shares airspace with the other. Each driver loads independently into its own 0.63 cu ft sealed chamber — correct acoustic alignment on both sides.
1.5" Double-Layer — Dowel Reinforced Stack Fab
Two bonded layers of Langboard Elite 3/4" MDF at 1.5 inches total, further reinforced with dowels throughout the assembly. At 1,000 watts RMS combined, double-layer stack-fab construction eliminates baffle resonance at the structural level.
Single Proline X Terminal Cup — Pre-Wired to Both Drivers
One Proline X ABS/carbon fiber terminal cup with stainless hardware and copper ring terminals serves the entire enclosure. Pre-wired internally with 12-gauge OFC to both driver positions. One amplifier run feeds both drivers.
8/32 Threaded Inserts — Machine Screws for Both Drivers
Both baffle positions are fitted with 8/32 threaded inserts. Stainless machine screws are included for both GUS-10 drivers. Each driver mounts to steel — consistent clamping force, no stripping risk, clean reinstallation at any service interval.
Active EQ Required — Identical Character to the Single GUS-10
Both GUS-10 drivers have Qts of 0.35, Fs of 16.91 Hz. The 0.707 Qtc alignment in each chamber produces flat anechoic response requiring active shelf EQ in-cabin. A Goldhorn DSP is the correct companion. Two drivers make the response louder — they do not change its character.
23mm Minimum Front Clearance — Both Drivers
ResoNix specifies 23mm minimum clearance between the GUS-10's surround and any surface in front of the driver. Confirm this at both driver positions against seat cushion, cargo cover, or any other nearby surface before finalizing the install.
Front-Firing or Downfiring — Feet Included
Rubber feet for downfiring installation are included. The GUS-10's vented rear cone assembly allows the pole vent to be fully obstructed without acoustic penalty — downfire is viable in tight enclosures. Choose the orientation that makes the install cleanest and most serviceable.
Dowel-Reinforced Stack Fab — Three Mechanical Systems at Every Joint
Dowels throughout the stack-fab assembly resist shear forces at panel joints independent of adhesive condition. Dado joinery + adhesive + dowels — all three systems locking every joint against sustained load across the life of the installation.
Ready to Mount. Ready to Wire. Built for Active Systems.
The M10D-S GUS ships fully prepped. The Proline X terminal cup is installed and pre-wired with 12-gauge OFC to both driver positions — connect your amplifier run and wiring is complete. Both baffles use 8/32 threaded inserts with stainless machine screws included. Polyfill is factory-installed in both chambers independently. Rubber feet for downfiring are included.
Plan Your Wiring Before Selecting the Voice Coil Variant
The GUS-10 is a dual voice coil driver — available in Dual 2Ω (D2) and Dual 4Ω (D4). With two drivers the wiring combinations produce multiple final impedance options. The recommended configuration for most builds is two D2 drivers, each wired series (4Ω per driver), then both in parallel (2Ω final). See the wiring chart above and confirm your amplifier's stable impedance before ordering. D2 T/S parameters are not yet finalized by ResoNix — D4 data is published and is the basis for this enclosure's volume calculation.
Where It Fits
At 34" × 14.75" × 8.25", the M10D-S GUS is wider and deeper than the single GUS-10 enclosure but remains significantly more compact than any conventional dual 10" sealed build. Measure carefully before ordering:
- Trunk floor — full-size sedans and sport sedans
- Cargo floor — mid-size and full-size SUVs
- Behind-seat — full-size crew cab trucks
- Dual front sub builds — DSP-controlled SQ systems
- SQ competition — maximum GUS-10 output at minimal depth
- High-output shallow installs — where two 10s replace one 12

Built From a Spec Sheet, Not a Sales Sheet
Every Proline X Micro Series enclosure is CNC-cut from Langboard Elite MDF — 3/4" (18mm) panels produced to published mill specifications. Most enclosure manufacturers source generic MDF without published data. We can tell you the internal bond rating, the modulus of elasticity, the modulus of rupture, and the face and edge screw holding strength for every panel in this enclosure — because we chose the material based on those numbers, not on price or availability.
Langboard Elite is produced in the United States. The specifications below are pulled directly from Langboard's published mill data and are verifiable. This is the same panel stock used across the full Proline X lineup.
Langboard Elite MDF — Published Mill Data
| Property | Value | Why It Matters |
|---|---|---|
| Panel Stock | Langboard Elite MDF | Named, verifiable panel source — not generic "high-density MDF" |
| Thickness | 3/4" (18mm) | Industry standard for subwoofer enclosures; panels below this flex under pressure |
| Density | 48.5 lbs/ft³ | Higher density = less porosity, better screw retention, reduced resonance |
| Internal Bond | 200 psi | Measures resistance to delamination under sustained internal pressure — the most enclosure-relevant spec on this sheet |
| Modulus of Rupture (MOR) | 4,200 psi | Bending strength before the panel breaks — relevant for larger unsupported baffle spans |
| Modulus of Elasticity (MOE) | 410,000 psi | Stiffness under load; higher MOE means less panel flex under bass pressure, less resonance |
| Face Screw Holding | 325 lbs | How firmly the panel surface holds a screw; critical for baffle joint integrity over time |
| Edge Screw Holding | 250 lbs | Panel edge retention — relevant for every joint that isn't face-to-face |
200 psi — The Number That Actually Matters for Enclosures
The internal bond rating measures how well the MDF panel resists delamination under sustained pressure applied perpendicular to the face. In a subwoofer enclosure, every bass transient generates a pressure pulse that pushes outward on every panel simultaneously. A panel that begins to delaminate internally loses stiffness gradually — the symptoms are slow: a box that starts to sound softer, less defined, less punchy over months of use. 200 psi internal bond is the spec that determines how long this enclosure holds its acoustic integrity under daily use at real power levels.
410,000 psi MOE — Less Flex, Less Resonance
The modulus of elasticity measures panel stiffness — resistance to bending under load. A stiffer panel flexes less under the pressure generated by a high-excursion driver at volume. Panel flex is a source of acoustic coloration: the panel itself begins to radiate sound at its own resonant frequency, adding distortion to the output. 410,000 psi stiffness combined with stack-fab layering and dado joinery means the panels stay rigid and the bracing controls resonance at the structure level — not the panel level. The bass you hear comes from the driver, not the box.
325 lb Face / 250 lb Edge — Joints That Stay Locked
Screw holding strength determines how firmly the panel grips a fastener at the face and at the edge. This matters most at the baffle joint — where the front panel meets the side panels and where the driver is mounted. A panel with low screw holding strength allows fasteners to loosen over time under vibration, leading to air gaps at the joint and loss of acoustic seal. 325 lb face screw holding strength means the baffle hardware stays put. Combined with dado joinery and adhesive, the front panel on a Proline X Micro Series enclosure is not going anywhere.
Named Panel Stock — Not "Premium MDF"
The phrase "premium MDF" or "high-density MDF" appears on marketing copy for enclosures across every price point, from $40 to $400. It is not a specification — it is a description with no defined standard. Langboard Elite is a named, sourced, mill-documented product with published data. We name it in our copy because naming it holds us accountable to the spec. You can look up Langboard Elite independently, verify the numbers on this page, and confirm you are getting what we say you are getting. That is the point.
