The SW10 mounts in \u003cstrong\u003e2.4 inches\u003c\/strong\u003e, or 2.25 inches front-loaded, and this dual cabinet stands \u003cstrong\u003e8 inches tall\u003c\/strong\u003e on a 30 by 15 inch footprint while delivering roughly 6 dB more maximum output than a single.\u003c\/p\u003e\u003cp\u003eEach 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 338.16 cm² each for \u003cstrong\u003e676.32 cm² across the pair\u003c\/strong\u003e. Combined power handling is 700 watts RMS.\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\u003eTotal internal gross volume is 1.202 cubic feet split into two chambers of \u003cstrong\u003e0.601 cubic feet gross each\u003c\/strong\u003e, matching Arc Audio's optimum sealed recommendation of 0.6 gross per driver almost exactly. Net works out to roughly 0.55 per chamber, producing \u003cstrong\u003eQtc 0.845, Fc 53.1 Hz, and a predicted F3 of 45.9 Hz\u003c\/strong\u003e per driver. That is the same alignment as the single-driver cabinet, so this is identical character with twice the cone area behind it.\u003c\/p\u003e\u003cp\u003eArc publishes complete Thiele-Small data for both series and parallel wiring, 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. One enclosure serves both wiring choices correctly.\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 honest tradeoff on this driver is a 39.3 Hz free-air resonance, so F3 sits in the mid 40s rather than the 30s. What you get in exchange is a 2.4 inch mounting depth and a dual 10 cabinet only 8 inches tall. Firing down into the floor, the sealed rolloff meets rising cabin gain below 60 Hz, which is exactly where this alignment is designed to work.\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. 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 Arc Audio SW10 subwoofers. Both are dual voice coil, so you set your final impedance at the drivers. 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":44540324347993,"sku":"PO 10D-S DF SW10","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_d8d35660-c194-4f14-a656-4617e7b119d0.jpg?v=1787107717","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-dual-10-enclosure-arc-audio-sw10","provider":"Audio Intensity","version":"1.0","type":"link"}
