At 7 inches tall on a 30 by 15 inch footprint, it fits under rear seats and in cargo wells that will not take a conventional box.\u003c\/p\u003e\u003cp\u003eThe T1 Slim 10 is available as the \u003cstrong\u003eT1S1-10\u003c\/strong\u003e (1Ω SVC) or \u003cstrong\u003eT1S2-10\u003c\/strong\u003e (2Ω SVC), both rated 500 watts RMS with 14.2mm of one-way Xmax in a 3.00 inch mounting depth. A 2.5 inch four-layer voice coil sits behind an anodized aluminum cone with Rockford's VAST surface technology and integrated trim ring. Both models share the same 9.13 inch cutout, 3.00 inch depth, and 0.03 cubic foot displacement, so this cabinet is direct fit for either impedance.\u003c\/p\u003e\u003cp\u003eThe 0.99 cubic foot net volume sits at the top of Rockford's published sealed range for this driver. The T1S1-10 lands at \u003cstrong\u003eQtc 1.15 with F3 at 37.8 Hz\u003c\/strong\u003e, the T1S2-10 at \u003cstrong\u003eQtc 1.27 with F3 at 38.6 Hz\u003c\/strong\u003e, computed from Rockford's published Thiele-Small parameters.\u003c\/p\u003e\u003cp\u003eThose Qtc figures deserve an honest explanation rather than a marketing one. The T1 Slim has a very high free-air Qts, 0.95 on the 1Ω model and 1.05 on the 2Ω. \u003cstrong\u003eQtc can never fall below Qts\u003c\/strong\u003e, no matter how large the enclosure, so there is no sealed volume that reaches a textbook 0.707 alignment with this driver. Every T1 Slim sealed box is underdamped by design. That is Rockford's intent: the response peak near the corner frequency reads as punch and impact in a vehicle, and it lets a shallow driver in a small box sound considerably bigger than its dimensions suggest. We build to the largest practical volume because that yields the lowest Qtc and the lowest F3 this driver can reach. Going smaller only raises both.\u003c\/p\u003e\u003cp\u003eFiring down into the floor, the peak sits where cabin gain is already climbing, which is exactly where this alignment is meant 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 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 T1S1-10 or T1S2-10. Both are single voice coil, so your final impedance is set by which model you buy.\u003c\/p\u003e\u003cp\u003eManufactured in Tullahoma, Tennessee. 1-year enclosure warranty.\u003c\/p\u003e","brand":"Proline X","offers":[{"title":"Default Title","offer_id":44540147105881,"sku":"PO 10-S DF T1","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_2e3e66f5-e959-4aa0-9dad-2b58151e6923.jpg?v=1787103457","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-10-enclosure-rockford-fosgate-t1-slim","provider":"Audio Intensity","version":"1.0","type":"link"}
