Performance Optimized Down Fire Wide Sealed Dual 10" Enclosure Kicker Solo-Baric L7T · Dual 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 8.125 inches tall, with each driver still in its own chamber. 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 8.6875 inches and gives each driver 0.60 cubic feet net. This cabinet is 41 x 12 x 8.125 and gives each driver 0.604 cubic feet net, within 0.004 cubic feet of the standard box. Acoustically they are effectively the same enclosure. 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 chambers match the standard dual L7T cabinet's airspace, and Kicker publishes separate Klippel data for each coil version. At 0.604 cubic feet net per chamber: Dual 2-Ohm: Qtc 0.744, Fc 53.9 Hz, F3 51.3 Hz. Dual 4-Ohm: Qtc 1.052, Fc 55.9 Hz, F3 43.0 Hz. The Dual 4-Ohm's higher Qts gives a peaked alignment in the same chamber.

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.

One side-mounted Proline X terminal cup with a single pair of posts, pre-wired in 12 gauge OFC to both driver positions in parallel. You do not wire the two chambers separately at the amplifier.

Final impedance is set at the drivers. The L7T 10 comes as a Dual 2-Ohm (46L7T102) or Dual 4-Ohm (46L7T104); use two of the same model and wire them identically. Kicker recommends 500 watts RMS per driver, 1000 combined. Confirm the load against your amplifier's minimum stable impedance.

Yes. Both positions are machined with a 9 5/16 inch square opening cut to Kicker's own published CNC template, including the 1-9/16 inch corner radii the L7T basket expects. The corners of a square cone are where the extra radiating area lives, and a round cutout would leave them overhanging unsupported baffle edge.

Side mounted, and there is one cup serving both chambers rather than one per chamber. 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 both baffles face the floor. The cup is our Proline X ABS and carbon fiber composite unit, recessed, with stainless hardware, copper ring terminals, and 12 gauge OFC pre-wired to both driver positions in parallel.

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 both chambers 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 each driver bolts to the inner layer. A full-height bonded 3/4 inch divider separates the chambers and ties the front and rear walls together across the 41 inch span. Both openings are 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 pair of Kicker Solo-Baric L7T 10, 46L7T102 or 46L7T104, two of the same model. The square cutouts and mounting depth are cut specifically for this driver at both positions.
