AudioControl Space SPC-10 Box: Ported 10" Shallow Professional Series Enclosure Single 10" Ported enclosure

Sealed, the SPC-10 is listed in our sealed wedge (PO 10-S W SPC10) at 0.60 cubic feet, Qtc 0.67, half power 61 Hz. The slot is gated at 480 W: the channel runs 20.5 m/s and the mouth 10.5, and the cone peaks at 8.0 of its 9 mm with the subsonic filter in place. Passband ripple is 0.0 dB. The SPC-10S4 (single 4 ohm) was run through the same cabinet: F3 34.4 Hz, passband ripple 0.1 dB, 7.7 of its 9 mm at 400 W. Tuning is chosen for in-car response rather than an anechoic curve: a vehicle adds roughly 12 dB per octave below about 45 Hz, and this tuning is where that sum comes out flattest across 25 to 60 Hz.

The Space SPC-10 also builds in the Performance Optimized ported wedge and ported down-fire, the smaller and cheaper boxes. The Professional cabinet is the step up for it: a 2.25 inch three-layer baffle with the woofer flush in the outer layer, and a slot port gated at 480 W. It carries a 2 year warranty, against 1 year on the Performance Optimized lines.

AudioControl does not publish the mounting hole locations for the Space SPC-10, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with one kit.

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 AudioControl Space SPC-10 at 89 percent of its usable travel at 480 W.

Not one we can show you. We do not build a sealed enclosure for the AudioControl Space SPC-10 and AudioControl 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 35.0 Hz the vent carries the load and cone travel drops to its minimum, which no sealed alignment can do.

It is a vertical slot beside the woofer, the full height of the cavity, 1.25 inches wide and 15.6 square inches. It runs 5.00 inches to the back wall and turns once along it for 19.44 inches; the fold costs about 1.5 Hz and the port is cut for it. The channel runs at 20.5 metres per second at 480 W, 54 percent of its turbulence limit, and the mouth edges carry a 1/2 inch roundover so the air leaves the face at 10.5 metres per second against the 17 metres per second threshold where a slot starts to chuff.

44 lb, 30.00" W x 14.00" H x 10.00" D external. Every Professional cabinet is priced the same way, by its size: this one is 2.43 cubic feet outside. Delivery to the 48 states is inside the price; it ships as a 44 lb parcel and checkout adds nothing. The $-18 difference is the larger box and the port this driver needs to run at its rating. Do not add polyfill; it ships dry on purpose.

No. This is an enclosure only, cut for the AudioControl Space SPC-10 specifically: the 9.130 inch cutout, the 3.500 inch mounting depth allowance and the 0.94 cubic foot alignment all come from AudioControl's published parameters. It fits both AudioControl versions, the SPC-10S2 (single 2 ohm) and the SPC-10S4 (single 4 ohm); the cabinet is tuned on the SPC-10S2 and was run with the SPC-10S4 too. Bring your own driver.
