At 8.3125 inches tall on a 30 by 15 inch footprint, it puts a full 12 into cargo floors and rear-wall positions where a conventional 12 inch box will not go.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eKicker 48CWRT124\u003c\/strong\u003e is a dual 4-ohm subwoofer with an 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 the CompRT turns up in UTV and open-cab builds as often as it does in trucks.\u003c\/p\u003e\u003cp\u003eThe Thiele-Small data behind this enclosure comes from \u003cstrong\u003eKlippel measurement\u003c\/strong\u003e rather than a datasheet estimate: Fs 30.3 Hz, Qts 0.7235, Vas 52.06 liters, Bl 19.1765 Tm, Mms 192.33 g, Sd 506.71 cm², and 13.35mm of linear excursion. A 30.3 Hz free-air resonance on a shallow 12 is excellent, and the 52 liter Vas is what gives this driver room to work in a sealed box.\u003c\/p\u003e\u003cp\u003eThe 1.25 cubic foot net volume produces \u003cstrong\u003eQtc 1.137, Fc 47.6 Hz, and a predicted anechoic F3 of 35.6 Hz\u003c\/strong\u003e. That is the deepest anechoic extension in the Proline X Down Fire line, and it comes from the driver's low resonance and large compliance rather than from an oversized cabinet.\u003c\/p\u003e\u003cp\u003eTwo things are worth being straight about. First, \u003cstrong\u003evolume matters more on this driver than on the CompRT 10\u003c\/strong\u003e. Dropping to 0.80 net would raise Qtc to 1.314 and push F3 to 39.5 Hz, costing nearly 4 Hz of extension. On the 10 the same proportional reduction costs only about 2 Hz. The extra 2 inches of cabinet height here buys something real.\u003c\/p\u003e\u003cp\u003eSecond, with a free-air Qts of 0.7235, \u003cstrong\u003esystem Qtc cannot fall below 0.7235 in any sealed enclosure\u003c\/strong\u003e, so this driver is mildly underdamped in every sealed box regardless of size. That is a design characteristic of the CompRT 12, not a limitation of this cabinet. It produces a modest lift near the corner frequency and the punchy, forward presentation the CompRT is known for. If you want the more damped and neutral of the two CompRT sizes, that is the 10 with its 0.618 Qts.\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 a \u003cstrong\u003edouble-layer 1.5 inch front baffle\u003c\/strong\u003e (two 3\/4 inch sheets bonded) for maximum baffle rigidity and driver isolation. Corners are square on Down Fire cabinets. The driver fires down into the floor with the terminal cup \u003cstrong\u003eside mounted\u003c\/strong\u003e, keeping the connection accessible with the cabinet in place. Terminal cup is our Proline X ABS\/carbon fiber composite pre-wired with 12 gauge OFC.\u003c\/p\u003e\u003cp\u003eBring your own Kicker 48CWRT124. Dual 4-ohm, so you set your final impedance at the driver: 2 ohms with the coils in parallel, 8 ohms in series.\u003c\/p\u003e\u003cp\u003eManufactured in Tullahoma, Tennessee. 1-year enclosure warranty.\u003c\/p\u003e","brand":"Proline X","offers":[{"title":"Default Title","offer_id":44540221063257,"sku":"PO 12-S DF CompRT","price":249.99,"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_3b1fa549-0c37-4b64-8e22-43435302bba0.jpg?v=1787105740","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-12-enclosure-kicker-comprt","provider":"Audio Intensity","version":"1.0","type":"link"}
