pair is vented at 37.5 Hz\u003c\/h3\u003e\n\u003cp\u003eThis cabinet gives the pair 1.48 cubic feet in one shared chamber, 0.74 per driver, vented at 37.5 Hz through a 26.4 square inch triangular port, and reaches 39.6 Hz anechoic in a 32 by 16 inch dual wedge. The port runs 25.0 m\/s in the channel and 16.7 at the flared mouth with both drivers at 700 watts, and each cone peaks at 5.6 of its 12.3 mm. Passband ripple is 0.4 dB. Our sealed dual wedge (PO 12D-S W RSS315HO) holds 0.62 cubic feet per chamber at Qtc 0.62 with half power at 61 Hz; this ported box reaches deeper.\u003c\/p\u003e\n\u003cp\u003eIt fits both Dayton versions, the RSS315HO-4 (single 4 ohm) and the RSS315HO-44 (dual 4 ohm); the pair is tuned on the RSS315HO-4 and the RSS315HO-44 was run through the same cabinet: F3 37.0 Hz, ripple 2.6 dB, each cone 5.2 of its 14 mm at 700 W.\u003c\/p\u003e\n\u003cdiv class=\"df-note\"\u003e\u003cp\u003eDayton publish a complete parameter table for the RSS315HO-4 that holds together on Qts, moving mass and motor strength. Mounting depth is the overall depth on Dayton's drawing, flange included, so it errs deep. Displacement is our 0.092 cubic foot estimate per driver, and tuning carries a 1.5 Hz fold loss that is an estimate, not a bench measurement.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eTwo drivers, one chamber, one port\u003c\/h3\u003e\n\u003cp\u003eA ported dual shares its air: one chamber and one port tuned for the pair, so the two cones load the same volume and the port carries both. That is the opposite of our sealed duals, which split the chambers. Windowed braces stiffen the long panels; their windows keep the cavity one chamber and leave each motor clear.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eTrunk-load wedge, explained\u003c\/h3\u003e\n\u003cp\u003eThe cabinet is 32.00 inches wide and 16 tall, 8.88 inches deep at the top and 14.70 at the base. The back rakes 20 degrees to sit against the rear seat; the baffle stays vertical, so the drivers fire rearward into the trunk.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eThe port is the product\u003c\/h3\u003e\n\u003cp\u003eThe port is a triangular slot formed by the floor, the back panel and one bevelled panel seated in dados, running 26.5 inches along the back and exiting through the side with a 0.5 inch roundover on all three edges of the mouth. Its 26.4 square inches carry both drivers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eRun a subsonic filter\u003c\/h3\u003e\n\u003cp\u003eBelow tuning the port stops loading the cones and excursion climbs fast. Set a subsonic filter near 32 Hz and leave it there.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eCut for this driver, not for a catalogue\u003c\/h3\u003e\n\u003cp\u003eBoth baffle openings are CNC cut to 11.10 in under 12.36 in recesses, centred 8.625 and 23.375 in from the mouth-side edge. The 5.75 in motors clear the port panel with 0.79 in to spare. Dayton print the bolt circle, so the threaded inserts are pressed into the baffle at the shop. Cut from Langboard Elite 3\/4 inch MDF with V-groove and dado joinery and a 1.5 inch double baffle.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003ePower, wiring and warranty\u003c\/h3\u003e\n\u003cp\u003eDayton rate the RSS315HO at 700 watts RMS per driver, 1400 across the pair; aim for 489 to 700 per driver. A pair of RSS315HO-4 (one 4 ohm coil each) is 2 ohms in parallel or 8 ohms in series. A pair of RSS315HO-44 (two 4 ohm coils each) lands on 4 ohms with each woofer's coils in series and the woofers in parallel, or 1 ohm with everything in parallel if the amplifier is rated for it. It ships dry: do not add polyfill to a ported box. 1 year limited warranty. Enclosure only, the drivers are purchased separately.
