Performance Optimized Wedge Ported 10" Enclosure | JL Audio 10W1v3 Single 10" Ported enclosure

A low resonance on a low Qts rolls off gently, so the volume is kept small to hold the passband in shape: 1.96 dB of anechoic ripple, an F3 of 32.7 Hz and 2.31 dB of in-car spread across 25 to 60 Hz at 33.5 Hz tuning. A bigger box would tune lower and read deeper on paper while the in-car curve bloated. The port uses 25.62 of 25.88 inches of path and runs at 18.4 metres per second in the channel against a 19.3 limit, 10.6 at the mouth. 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 2.3 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 12.16 inches deep at the base and 7.25 at the top, 30.00 wide and 14 tall.

Yes, at 26 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 JL Audio 10W1v3 at 61 percent of its usable travel at full rated power; without it there is no meaningful number to quote.

JL Audio rate the 10W1v3 at 300 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 61 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.

The two alignments converge at the bottom of the band on this driver rather than crossing cleanly, so there is no meaningful subsonic advantage either way. Above 25 Hz the vent is the louder of the two. The Performance Graphs tab plots this cabinet against JL Audio's recommended sealed box, 0.55 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 2.63 inch gap at the far end and exits through the side panel as the same triangle. Straight, no bend: 25.62 inches of path and 13.0 square inches of channel running at 18.4 metres per second, 52 percent of its turbulence limit. The three mouth edges are rounded over at 1/2 inch, so the opening at the face is 22.5 square inches and the air leaves it at 10.6 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 25.62 inches for 33.5 Hz. Stuff it and you move the tuning without shortening the port.

No. This is an enclosure only, cut for the JL Audio 10W1v3 specifically: the 9.055 inch cutout, the 4.606 inch mounting depth allowance and the 0.97 cubic foot alignment all come from JL Audio's published parameters. It fits both coil versions; the alignment published here is the -4. Bring your own driver.
