Performance Optimized Wedge Sealed Dual 10" Enclosure Musway MG10 · Dual 10" Sealed enclosure

The MG10, yes, in the dual 2 ohm version. The baffle is cut to 9.45 in, Musway's published cutout, under the 10.87 in frame. The 6.38 inch motor clears the cabinet with 3.32 inch to spare. Run two of the same coil so the chambers match.

Any other 10, no. The airspace is engineered around the MG10's own Qts and Vas, and a different woofer that happened to drop into the hole would not see the alignment printed on this page.

1.06 cubic feet net per chamber on Musway's published figures: the dual 2 ohm reads Qtc 0.702 with resonance at 45.8 Hz and half power at 46.2 Hz. The volume is Musway's own maximum recommended sealed airspace for the MG10, 30 litres. That is maximally flat, the reference sealed alignment.

Cabinet gain in a vehicle lifts the bottom end further, so in the car this reads deeper than the anechoic figures.

Musway rates the MG10 at 500 watts RMS per driver, so target 350 to 500 watts RMS per driver at the final load.

Musway sells the MG10 as dual 2 ohm; a matched pair should share a coil. A pair of dual 2 ohm drivers lands on 2 ohms with each woofer's coils in series and the two woofers in parallel, or 8 ohms all in series. Anything under 1 ohm, and many amplifiers at 1 ohm, is outside what the amplifier is built for, so series wiring is the safe default. Confirm your amplifier's minimum stable impedance first.

The seat-side face carries a 20 degree rake that matches the lean of a factory rear seat back, so the cabinet sits flush against it and the cargo space in front stays usable. The baffle is the vertical trunk-lid-side face, so the drivers fire rearward into the trunk cavity.

The trunk acts as an acoustic extension for the sealed box, and the cabin adds real output below 50 Hz, so in-vehicle response runs deeper than the anechoic 46.2 Hz on this page.

Two drivers sharing one sealed volume load each other: each driver's compression stroke becomes the pressure the other works against, which blurs the alignment either would have alone. A bonded full-height 3/4 inch divider gives each driver its own 1.06 cubic feet and its own polyfill.

It also means a failure in one driver does not unload the other, and the alignment on this page is the alignment in each chamber, not an average across a shared box.

Anechoic F3 is 46.2 Hz per chamber. Below Qtc 0.707 the rolloff is gentle and F3 sits above fc, which is what an over-damped sealed box does.

Those figures exclude cabin gain. In a car the cabin's transfer function adds real output below 50 Hz, so in-vehicle response runs deeper than the numbers above.

No. Polyfill is already installed in both chambers as a light wall lining to control internal reflections, and the quantity is chosen so it does not change the acoustic volume.

Do not add more. Packing a sealed box with fill makes it behave as though it were larger, which walks the alignment away from the 1.06 cubic feet per chamber this cabinet was built to.

No driver. This is an enclosure only. You receive the cabinet finished in plush black carpet with the gloss black acrylic baffle insert, one side-mounted pre-wired terminal cup to both positions, the polyfill lining already in place, and a threaded insert kit with stainless machine screws.

The inserts ship loose on purpose: Musway prints no bolt circle for the MG10, so you set the driver in the recess, mark its holes, drill and press the inserts. The pair of Musway MG10 is purchased separately, and the cabinet is cut direct fit to it, not a general purpose 10 inch box.
