Performance Optimized Wedge Sealed 12" Enclosure | Deaf Bonce Machete M12 v2 Single 12" Sealed enclosure

Yes. The coil versions share a frame, the same 11.08 in cutout and the same 6.14 in mounting depth, so the cabinet fits either. They differ electrically, and nothing about the enclosure changes.

1.10 cubic feet net. That is the Butterworth volume for the M12 v2 D2 coil, computed from Deaf Bonce's published Fs, Qts and Vas. Deaf Bonce publish no sealed recommendation for the M12 v2 (their manual recommends a bass-reflex box), so this alignment is ours, chosen for damping and transient control rather than peak output. In this box the M12 v2 D2 lands at Qtc 0.707, maximally flat, the reference musical alignment, and the M12 v2 D4 at Qtc 0.702. System resonance sits at 48.4 to 50.8 Hz. The box is 1.19 cu ft gross before the driver's displacement. Deaf Bonce do not publish driver displacement; the 0.08 cu ft carried here is an estimate for a 12 inch motor, and only the gross figure depends on it.

Deaf Bonce rate the M12 v2 at 500 watts RMS. The M12 v2 D2 carries two 2 ohm coils: 4 ohms in series or 1 ohm in parallel. The M12 v2 D4 carries two 4 ohm coils: 8 ohms in series or 2 ohms in parallel. Run the coils in series unless the amplifier is rated stable at the parallel load; 1 ohm is beyond most amplifiers. Aim for roughly 350 to 500 watts at the impedance you wire.

The angled seat-side face matches the roughly 20 degree lean of a factory rear seat, so the cabinet sits flat against it instead of leaving a wasted triangle. The vertical trunk-lid-side face carries the driver, firing rearward into the trunk cavity.

A rectangular box of this volume wastes the triangle of space a leaning rear seat creates, and firing into the trunk lid rather than at the seat back gives the cabin a smoother path to the passengers. The wedge takes the same air volume and puts it where the car actually has room.

Half power lands at 48.4 to 51.1 Hz anechoic, before any cabin gain. Qtc is 0.702 to 0.707. These figures exclude cabin gain, which in most vehicles adds real output below 40 Hz. Deaf Bonce publish the M12 v2's free-air resonance at 31.5 to 31.8 Hz.

No. Polyfill is already installed as a light wall lining and the quantity is chosen so it does not change the acoustic volume. Do not add more.

No. This is an enclosure only. You receive the cabinet finished in plush black carpet, with threaded inserts at the driver position, stainless machine screws, one side-mounted pre-wired terminal cup and the polyfill lining already installed.
