Performance Optimized Wedge Ported 10" Enclosure Skar Audio VS-10 · Single 10" Ported enclosure

Sealed, the VS-10 needs 28.95 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The wedge's port runs 21.8 m/s in the channel and 13.3 at the flared mouth at Skar's 500 W rating, with the cone peaking at 8.2 of its 9.1 mm. Passband ripple is 3.0 dB. Skar's own ported recommendation is 1.60 cubic feet at 33 Hz, before driver and port displacement. Tuning is chosen for in-car response rather than an anechoic curve: a vehicle adds roughly 12 dB per octave below about 45 Hz. In this cabinet that lands at 3.9 dB of in-car spread across 25 to 60 Hz.

The raked face is the seat side. A factory rear seat back leans about 20 degrees off vertical, so the cabinet sits flat against it and uses floor a square box wastes. The baffle stays vertical and fires rearward into the trunk, which acts as the acoustic extension into the cabin. This one is 13.04 inches deep at the base and 8.12 at the top, 30.00 wide and 13.5 tall.

Yes, at 29 Hz, 24 dB per octave. Below tuning a vented box stops loading the cone and excursion runs away toward DC. With the filter in place this cabinet puts the Skar Audio VS-10 at 90 percent of its usable travel at full rated power; without it there is no meaningful number to quote.

Skar Audio rate the VS-10 at 500 W RMS and that is the thermal ceiling. The Performance Graphs tab shows the mechanical limit, the power at which the cone reaches the end of its travel in this cabinet: here the cone sits at 90 percent of usable travel at the rating, so heat is what stops you, not travel. A D2 coil is 4 ohms in series or 1 ohm in parallel; run series unless the amplifier is rated for 1 ohm. A D4 is 8 series or 2 parallel.

Below about 21 Hz, yes. The maker's recommended sealed box is louder down there by up to 0.8 dB, because a sealed box rolls off gently where a vented one falls away steeply under tuning. Above that this alignment is the louder of the two for the same power. The Performance Graphs tab plots this cabinet against Skar Audio's recommended sealed box, 0.50 cu ft.

It is a triangular slot in the bottom-rear corner: the floor and the raked back wall are two sides, one bevelled panel is the third. It runs across the cabinet, opens into the box through a 2.80 inch gap at the far end and exits through the side panel as the same triangle. Straight, no bend: 25.45 inches of path and 16.9 square inches of channel running at 21.8 metres per second, 54 percent of its turbulence limit. The three mouth edges are rounded over at 1/2 inch, so the opening at the face is 27.7 square inches and the air leaves it at 13.3 metres per second against the 17.0 threshold where a slot port starts to chuff; the panel's throat end is rounded at 3/8 inch for the same reason. The terminal cup is on the other side.

No, and do not add any. Every sealed Proline X enclosure ships with polyfill; a ported one must not, because damping changes the effective volume the port is tuned against. The port here is cut to 25.45 inches for 36.5 Hz. Stuff it and you move the tuning without shortening the port.

No. This is an enclosure only, cut for the Skar Audio VS-10 specifically: the 9.075 inch cutout, the 3.890 inch mounting depth allowance and the 1.07 cubic foot alignment all come from Skar Audio's published parameters. It fits both coil versions (D2 and D4), and the cabinet was checked against both. Bring your own driver.
