Performance Optimized Wedge Sealed 15" Enclosure | Deaf Bonce Machete M15 v2 Sport Single 15" Sealed enclosure

Yes. The coil versions share a frame, the same 13.95 in cutout and the same 7.52 in mounting depth, so the cabinet fits either. They differ electrically, and nothing about the enclosure changes.

2.23 cubic feet net. That is the Butterworth volume for the M15 v2 D1 Sport coil, computed from Deaf Bonce's published Fs, Qts and Vas. Deaf Bonce publish no sealed recommendation for the M15 v2 Sport (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 M15 v2 D1 Sport lands at Qtc 0.707, maximally flat, the reference musical alignment, and the M15 v2 D2 Sport at Qtc 0.729. System resonance sits at 42.2 to 43.8 Hz. The box is 2.36 cu ft gross before the driver's displacement. Deaf Bonce do not publish driver displacement; the 0.12 cu ft carried here is an estimate for a 15 inch motor, and only the gross figure depends on it.

Deaf Bonce rate the M15 v2 Sport at 950 watts RMS. The M15 v2 D1 Sport carries two 1 ohm coils: 2 ohms in series or 0.5 ohm in parallel. The M15 v2 D2 Sport carries two 2 ohm coils: 4 ohms in series or 1 ohm in parallel. Run the coils in series unless the amplifier is rated stable at the parallel load; 0.5 ohm is beyond most amplifiers. Aim for roughly 665 to 950 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 41.0 to 43.8 Hz anechoic, before any cabin gain. Qtc is 0.707 to 0.729. These figures exclude cabin gain, which in most vehicles adds real output below 40 Hz. Deaf Bonce publish the M15 v2 Sport's free-air resonance at 30.12 to 31.6 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.
