Performance Optimized Down Fire Wide Sealed Dual 10" Enclosure Kicker CompRT · Dual 10" Sealed enclosure

Because it is only 12 inches deep. The standard Performance Optimized Down Fire cabinet for the Kicker CompRT is 30 wide by 15 deep, and this version is for spaces 3 inches shallower than that, under a rear bench or on a narrow cargo floor.

Airspace has to come from somewhere. Losing depth means recovering it along the length, so the cabinet runs 41 inches long and stands 9.5 inches tall. If you have 15 inches of depth, the standard cabinet is shorter in length and is the better pick; if you have 12 inches of depth and 41 inches of run, this is the shape that works.

Same driver, different shape. The standard cabinet is 30 by 15 by 10.125 inches and was built to 0.793 cubic feet net per chamber. This cabinet is 41 by 12 by 9.5 inches and holds 0.798 cubic feet net per chamber.

The airspace is essentially the same, within about a hundredth of a cubic foot, so the two behave the same way. The choice is about the space you have: the standard box is deeper and shorter in length, this one is long and shallow.

Because two drivers in a shared sealed volume interact acoustically. Each driver's compression phase becomes the pressure environment the other driver is working against, which smears transient response and blurs the alignment each would have on its own.

A full-height bonded 3/4 inch MDF divider eliminates that. Each CompRT gets its own 0.798 cubic feet net and its own polyfill, and the 48CWRT104 produces its own sealed alignment at Qtc 0.923 in each chamber. Separate chambers are the standing design rule on every Proline X dual sealed enclosure.

For the 48CWRT104, Klippel measurement, not a datasheet summary. That is why this page lists Cms, Bl, Mms, Sd, Qes and Qms alongside the usual Fs, Qts and Vas. The alignment was computed directly from those values: Qtc 0.923, Fc 48.2 Hz, F3 39.5 Hz per chamber.

The dual 2 ohm 48CWRT102 figures come from a library parameter set (Fs 28.7 Hz, Qts 0.4865, Vas 35.36 L), not from Klippel data, and give Qtc 0.779, Fc 46.0 Hz, F3 42.1 Hz. Treat those as a guide to a few hundredths.

The enclosure uses 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. Each 48CWRT104 is dual 4-ohm, so how you wire the two coils on each driver determines the load the amplifier sees through the cup. Wire both drivers identically, since mismatched wiring between chambers splits power unevenly, and confirm the load against your amplifier's minimum stable impedance.

Side mounted, and there is one cup serving both driver positions rather than one per chamber. Every Proline X Performance Optimized enclosure uses a side mounted terminal cup regardless of alignment, whether standard, wedge, or down fire. On this cabinet that keeps the connection accessible with the enclosure in its installed position, 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 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 both chambers airtight under sustained pressure cycling. The chamber divider is a full-height bonded 3/4 inch panel, which also ties the front and rear walls together across the 41 inch span. The front baffle is a double layer at 1.5 inches, two bonded 3/4 inch sheets with the outer layer machined as a flush recess, at both driver positions. Polyfill is installed in each chamber 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 48CWRT104 subwoofers. The cutouts and mounting depth are direct fit for the 48CWRT104, and the feet ship uninstalled in the box.
