Performance Optimized Wedge Ported 10" Enclosure | PowerBass S-10T Single 10" Ported enclosure

PowerBass label the S thin line for small sealed boxes. Vented at 35.5 Hz it reaches 35.6 Hz anechoic on 1.43 dB of ripple and reads 1.94 dB of spread across 25 to 60 Hz in the car, a flatter result than a 40 Hz motor usually gives, because the shallow cabinet keeps the volume modest. The port takes 25.20 of the 25.88 inches available and runs at 16.8 metres per second in the channel against an 18.6 limit, 9.7 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 1.8 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 11.91 inches deep at the base and 7.00 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 PowerBass S-10T at 86 percent of its usable travel at full rated power; without it there is no meaningful number to quote.

PowerBass rate the S-10T at 275 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 86 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.

Not one we can show you. We do not build a sealed enclosure for the PowerBass S-10T and PowerBass publish no sealed volume for it, so the Performance Graphs tab carries no ported-versus-sealed chart: the only sealed box left to plot would be this cabinet stuffed and sealed, which nobody would build, and a comparison against it would tell you nothing you could buy. What a vented box gives up is the region below tuning, where the cone unloads and the 28 Hz subsonic filter takes over; around 35.5 Hz the vent carries the load and cone travel drops to its minimum, which no sealed alignment can do.

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 3.05 inch gap at the far end and exits through the side panel as the same triangle. Straight, no bend: 25.20 inches of path and 13.0 square inches of channel running at 16.8 metres per second, 50 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 9.7 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 25.20 inches for 35.5 Hz. Stuff it and you move the tuning without shortening the port.

No. This is an enclosure only, cut for the PowerBass S-10T specifically: the 9.173 inch cutout, the 3.250 inch mounting depth allowance and the 0.88 cubic foot alignment all come from PowerBass's published parameters. It fits both coil versions; the alignment published here is the . Bring your own driver.
