It carries the same 30 by 15 inch footprint as the single, standing 10.125 inches tall, and delivers roughly 6 dB more maximum output than one driver in the same alignment.\u003c\/p\u003e\u003cp\u003eEach \u003cstrong\u003eKicker 48CWRT104\u003c\/strong\u003e is a dual 4-ohm subwoofer rated 400 watts RMS with a 3-7\/16 inch top-mount depth. Injection-molded polypropylene cone, Santoprene rubber surround with Kicker's signature red double stitching, SoloKon integrated cone-to-backplate design, and Forced-Air Cooling that runs the motor roughly 20 percent cooler. The cone and surround are UV resistant, which is why this driver turns up in UTV and open-cab builds as often as it does in trucks.\u003c\/p\u003e\u003cp\u003eThis enclosure follows the Proline X standing design rule for dual sealed builds: \u003cstrong\u003etwo fully separate chambers\u003c\/strong\u003e divided by a bonded full-height 3\/4 inch MDF panel, giving each driver its own dedicated airspace. Two drivers sharing one sealed volume interact acoustically, with each driver's compression phase becoming the other's pressure environment, which smears transient response and blurs the alignment each would have on its own. Separate chambers eliminate that entirely.\u003c\/p\u003e\u003cp\u003eThe Thiele-Small data behind this design comes from \u003cstrong\u003eKlippel measurement\u003c\/strong\u003e rather than a datasheet estimate: Fs 32.3 Hz, Qts 0.618, Vas 27.80 liters, Bl 19.158 Tm, Mms 150.85 g, Sd 349.67 cm², and 13.35mm of linear excursion. A 32.3 Hz free-air resonance on a shallow 10 is genuinely low, and it is what allows this driver to reach real low-frequency output from a thin cabinet.\u003c\/p\u003e\u003cp\u003eTotal internal gross volume is 1.646 cubic feet split into two 0.823 cubic foot chambers, giving \u003cstrong\u003e0.793 cubic feet net per driver\u003c\/strong\u003e after displacement. Each chamber produces \u003cstrong\u003eQtc 0.924, Fc 48.3 Hz, and a predicted anechoic F3 of 39.5 Hz\u003c\/strong\u003e — effectively identical to the single-driver Down Fire cabinet for this driver. You get the same controlled alignment and the same character, with twice the cone area behind it.\u003c\/p\u003e\u003cp\u003eFiring down into the floor, the sealed rolloff meets rising cabin gain below 60 Hz, and in-car response extends well below the anechoic figure.\u003c\/p\u003e\u003cp\u003eConstruction is the full Proline X Performance Optimized platform: ShopSabre CNC-cut Langboard Elite MDF with \u003cstrong\u003eV-groove and dado joinery\u003c\/strong\u003e, perimeter cross-bracing, and \u003cstrong\u003edouble-layer 1.5 inch front baffles\u003c\/strong\u003e (two 3\/4 inch sheets bonded) at both driver positions for maximum baffle rigidity and driver isolation. Corners are square on Down Fire cabinets. Both drivers fire down into the floor, and \u003cstrong\u003eone side-mounted\u003c\/strong\u003e Proline X ABS\/carbon fiber composite terminal cup serves both chambers, fed in parallel to both driver positions with 12 gauge OFC.\u003c\/p\u003e\u003cp\u003eBring your own pair of Kicker 48CWRT104 subwoofers. Both are dual 4-ohm, so you set your final impedance by how you wire the voice coils at each driver. Wire both drivers identically.\u003c\/p\u003e\u003cp\u003eManufactured in Tullahoma, Tennessee. 1-year enclosure warranty.\u003c\/p\u003e","brand":"Proline X","offers":[{"title":"Default Title","offer_id":44540206612569,"sku":"PO 10D-S DF CompRT","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/1389\/files\/proline-x-micro-series-dual-15-sealed-enclosure-built-for-resonix-gus-15subwoofer-enclosuresproline-x-9360178_97ec11e2-167b-4906-8949-046ca5df8ac1.jpg?v=1787105547","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-dual-10-enclosure-kicker-comprt","provider":"Audio Intensity","version":"1.0","type":"link"}
