Performance Optimized Down Fire Wide Sealed 10" Enclosure Kicker Solo-Baric L7T · Single 10" Sealed enclosure

Because it is only 12 inches deep. The standard Performance Optimized Down Fire platform is 30 wide by 15 deep, and this application needs a cabinet that fits a space three inches shallower than that.

The airspace has to come from somewhere, so the cabinet runs 41 inches long instead of 30 and stands 5.25 inches tall. If you have 15 inches of depth, the standard cabinet is the pick; if your space is long and shallow, under a rear bench or on a narrow cargo floor, this is the shape that fits.

The standard cabinet is 30 x 15 x 5.375 inches and holds 0.60 cubic feet net. This cabinet is 41 x 12 x 5.25 and holds 0.625 cubic feet net, 0.025 cubic feet more, because its height is set by the L7T's mounting depth rather than by a volume target. More air means a lower, more damped Qtc, which is the safe direction. The choice is about shape: the standard box needs 15 inches of depth, this one needs 12 inches of depth and 41 inches of run.

The cabinet height is set by the L7T's 3 3/4 inch mounting depth, and Kicker publishes separate Klippel data for each coil version. At 0.625 cubic feet net: Dual 2-Ohm: Qtc 0.736, Fc 53.2 Hz, F3 51.2 Hz. Dual 4-Ohm: Qtc 1.039, Fc 55.2 Hz, F3 42.7 Hz. The Dual 4-Ohm's higher Qts gives a peaked alignment in the same box.

Those are anechoic figures. Firing into the floor, the sealed rolloff meets rising cabin gain, so in-car response runs deeper than the numbers above.

Kicker recommends 500 watts RMS of amplifier power, with a peak rating of 1000 watts measured per ANSI/CTA-2031-A. Sensitivity is 85.98 dB published and 85.645 dB in Kicker's own Klippel measurement, so treat mid 85 as the working number.

Both versions are dual voice coil, so final impedance is set at the driver. A clean 500 watts is worth more than a larger amplifier driven into clipping.

From us, and we would rather say so than let it look like a manufacturer number. Kicker does not publish a displacement figure for the L7T on the product page, in the Thiele-Small set or on the dimension drawing. The 0.07 cubic feet used in the net volume is our estimate from the square cutout and the 3 3/4 inch mounting depth.

Side mounted. Every Proline X Performance Optimized enclosure uses a side mounted terminal cup, and on a down fire cabinet that keeps the connection accessible with the enclosure installed, since the baffle faces the floor. The cup is our Proline X ABS and carbon fiber composite unit, recessed, with stainless hardware, copper ring terminals, and pre-wired 12 gauge OFC.

V-groove and dado joinery, CNC cut on ShopSabre routers from Langboard Elite MDF. Every panel joint is a machined interlocking groove that mechanically locks the panels before adhesive is applied, which keeps the cabinet airtight under sustained pressure cycling. Corners are square, the Down Fire series standard, with no radii.

The front baffle is a double layer at 1.5 inches, with the outer layer machined as a flush recess so the driver bolts to the inner layer. A windowed U-brace ties the long panels together across the 41 inch span. The opening is cut square to Kicker's published template. Polyfill is installed as a light wall lining. Assembled and inspected in Tullahoma, Tennessee.

No. This listing is for the enclosure only. Bring your own Kicker Solo-Baric L7T 10 in either coil version, 46L7T102 or 46L7T104. The square cutout and mounting depth are cut specifically for this driver.
