The SW10 mounts in \u003cstrong\u003e2.4 inches\u003c\/strong\u003e, or 2.25 inches front-loaded, and this cabinet stands just \u003cstrong\u003e5.0625 inches tall\u003c\/strong\u003e on a 30 by 15 inch footprint.\u003c\/p\u003e\u003cp\u003eThe Arc Audio SW10 is a dual voice coil subwoofer available in \u003cstrong\u003edual 2Ω or dual 4Ω\u003c\/strong\u003e, rated 350 watts RMS and 700 watts peak. Cutout is 9.1 inches, outer diameter 10.3 inches. Cone area is 338.16 cm² with a 16.365 Tm force factor in series wiring.\u003c\/p\u003e\u003cp\u003eArc publishes full Thiele-Small data for this driver in both series and parallel wiring configurations, and the two land within a hair of each other: Fs 39.3 versus 39.0 Hz, Qts 0.624 versus 0.634, Vas 12.96 versus 13.33 liters. That consistency means one enclosure serves both wiring choices properly, which is not always true of dual voice coil drivers.\u003c\/p\u003e\u003cp\u003eThe 0.604 cubic foot gross volume matches Arc Audio's own optimum sealed recommendation of 0.6 gross. That produces \u003cstrong\u003eQtc 0.843, Fc 53.1 Hz, and a predicted F3 of 45.9 Hz\u003c\/strong\u003e. A Qts of 0.624 is a healthy, moderate figure, so unlike some shallow drivers this one reaches a properly controlled alignment rather than being locked underdamped regardless of box size.\u003c\/p\u003e\u003cp\u003eNote that Arc publishes their sealed recommendations as \u003cstrong\u003egross\u003c\/strong\u003e volume rather than net, which is unusual. Most manufacturers state net. We have built to their gross figure as published.\u003c\/p\u003e\u003cp\u003eThe tradeoff on this driver is honest: a 39.3 Hz free-air resonance is higher than the deeper-reaching shallows in this program, so F3 lands in the mid 40s rather than the 30s. What you get in exchange is a 2.4 inch mounting depth and a cabinet just over 5 inches tall. If your clearance is the binding constraint, this is the driver that fits.\u003c\/p\u003e\u003cp\u003eFiring down into the floor, the sealed rolloff meets rising cabin gain below 60 Hz. Arc's own documentation notes cabin gain adds roughly 12 dB per octave below 50 Hz in most vehicles.\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 Arc Audio SW10. Dual voice coil, so you set your final impedance at the driver.\u003c\/p\u003e\u003cp\u003eManufactured in Tullahoma, Tennessee. 1-year enclosure warranty.\u003c\/p\u003e","brand":"Proline X","offers":[{"title":"Default Title","offer_id":44540305670233,"sku":"PO 10-S DF SW10","price":239.99,"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_eac4fc6e-4252-4b86-afe4-ff2cd33574b9.jpg?v=1787107448","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-10-enclosure-arc-audio-sw10","provider":"Audio Intensity","version":"1.0","type":"link"}
