Performance Optimized Wedge Ported 10" Enclosure | JL Audio 10TW1 Single 10" Ported enclosure

35 Hz gives a 41.5 Hz motor an anechoic F3 of 29.3 Hz on 2.30 dB of ripple, and the price is paid in the car: 5.64 dB of spread across 25 to 60 Hz, the widest of JL's tens in this line, because the motor has stopped contributing before cabin gain arrives. If the install has the depth, the 10W0v3 in this line reads 1.22 dB. JL's own sealed recommendation is 0.35 cubic feet. The port takes 25.58 of the 25.66 inches available and runs at 19.4 metres per second in the channel against a 20.1 limit, 11.6 at the rounded 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 5.6 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 12.91 inches deep at the base and 8.00 at the top, 30.00 wide and 14 tall.

Yes, at 28 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 10TW1 at 76 percent of its usable travel at full rated power; without it there is no meaningful number to quote.

JL Audio rate the 10TW1 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 76 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, 0.35 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 2.67 inch gap at the far end and exits through the side panel as the same triangle. Straight, no bend: 25.58 inches of path and 15.5 square inches of channel running at 19.4 metres per second, 53 percent of its turbulence limit. The three mouth edges are rounded over at 1/2 inch, so the opening at the face is 25.9 square inches and the air leaves it at 11.6 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 25.58 inches for 35.0 Hz. Stuff it and you move the tuning without shortening the port.

No. This is an enclosure only, cut for the JL Audio 10TW1 specifically: the 9.055 inch cutout, the 4.370 inch mounting depth allowance and the 1.06 cubic foot alignment all come from JL Audio's published parameters. It fits both coil versions; the alignment published here is the -2. Bring your own driver.
