At 6.25 inches tall on a 30 by 15 inch footprint, it fits under seats and in cargo wells that will not take a conventional box.\u003c\/p\u003e\u003cp\u003eThe Arc Audio A10 is available as the \u003cstrong\u003eA10D2\u003c\/strong\u003e (dual 2Ω) or \u003cstrong\u003eA10D4\u003c\/strong\u003e (dual 4Ω), both rated 250 watts RMS and 500 watts musical with 8mm of one-way Xmax in a 3.77 inch mounting depth. Cutout is 9.06 inches and total depth is 4.24 inches.\u003c\/p\u003e\u003cp\u003eWhat sets this driver apart is its \u003cstrong\u003e26.995 Hz free-air resonance\u003c\/strong\u003e. That is exceptionally low for a 10 inch subwoofer of any depth, let alone one that mounts in under four inches. Most 10s sit in the mid to high 30s. Arc pairs that low Fs with a moderate Qts of 0.477 on the D2 and 0.506 on the D4, which is the combination that lets this driver reach a properly damped sealed alignment rather than being forced into an underdamped one.\u003c\/p\u003e\u003cp\u003eThe 0.859 cubic foot gross volume matches Arc Audio's own optimum sealed recommendation of 0.85 gross. Net after driver displacement is approximately 0.80 cubic feet, producing \u003cstrong\u003eQtc 0.796 with F3 at 40.6 Hz on the D2\u003c\/strong\u003e, and \u003cstrong\u003eQtc 0.854 with F3 at 39.0 Hz on the D4\u003c\/strong\u003e.\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, so this cabinet is the enclosure Arc designed the driver around.\u003c\/p\u003e\u003cp\u003eFiring down into the floor, the sealed rolloff meets rising cabin gain below 60 Hz. Arc's own documentation notes that cabin gain adds roughly 12 dB per octave below 50 Hz in most vehicles, and with a 27 Hz Fs this driver has the low-end capability to take advantage of it.\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 A10D2 or A10D4. Both are 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":44540250390617,"sku":"PO 10-S DF A10","price":229.99,"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_9e067109-8c41-4cba-b6af-810c6754683c.jpg?v=1787106944","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-10-enclosure-arc-audio-a10","provider":"Audio Intensity","version":"1.0","type":"link"}
