At 6.875 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 P3 Shallow 10 comes as the \u003cstrong\u003eP3SD2-10\u003c\/strong\u003e (dual 2Ω) or \u003cstrong\u003eP3SD4-10\u003c\/strong\u003e (dual 4Ω), both rated 300 watts RMS with 8.4mm of one-way Xmax in a 3.50 inch mounting depth. A 2.5 inch four-layer voice coil sits behind an anodized aluminum cone with Rockford's VAST surface technology, and the driver ships with a painted aluminum trim ring. Both models share the same 9.06 inch cutout, 3.50 inch depth, and 0.074 cubic foot displacement, so this cabinet is direct fit for either impedance.\u003c\/p\u003e\u003cp\u003eThe 0.92 cubic foot net volume sits at the top of Rockford's published sealed range for this driver. The P3SD2-10 lands at \u003cstrong\u003eQtc 0.795 with F3 at 44.9 Hz\u003c\/strong\u003e, the P3SD4-10 at \u003cstrong\u003eQtc 0.969 with F3 at 39.6 Hz\u003c\/strong\u003e, computed from Rockford's published Thiele-Small parameters.\u003c\/p\u003e\u003cp\u003eThe two coil options behave differently enough here to be worth understanding. The D2 has a free-air Qts of 0.64 and lands close to a flat alignment, giving the more controlled and accurate presentation. The D4 has a Qts of 0.78 and lands near unity Qtc, which trades some damping for a lift near the corner frequency and a slightly lower F3. Neither is wrong. The D2 is the choice for accuracy, the D4 for impact.\u003c\/p\u003e\u003cp\u003eWorth noting on the D2: its 0.64 Qts means a textbook 0.707 alignment is technically reachable, but it would take roughly 2.27 cubic feet net. That is not a shallow-mount cabinet anymore. At 0.92 net you are as close to flat as this format sensibly allows.\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 figures above.\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 P3SD2-10 or P3SD4-10. Both are dual voice coil, so you set your final impedance by how you wire the coils 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":44540174499929,"sku":"PO 10-S DF P3S","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_30f8c127-835c-4fbd-a503-621b61205129.jpg?v=1787104219","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-10-enclosure-rockford-fosgate-punch-p3-shallow","provider":"Audio Intensity","version":"1.0","type":"link"}
