is the 8 inch from Dayton's Reference HF (high-fidelity) line: 29.6 Hz, Qts 0.57, 23.7 litres of Vas and 9 mm of excursion. In the wedge it gets 0.85 cubic feet net, vented at 37.5 Hz through an 11.7 square inch triangular port, for an anechoic F3 of 32.6 Hz. The cabinet is 27 inches wide and 11.75 tall, 8.50 inches deep at the top and 12.78 at the base, and rakes back against the rear seat like every Proline X wedge.\u003c\/p\u003e\n  \u003cp\u003eSealed, the RSS210HF is listed in our sealed wedge at 1.55 cubic feet, Qtc 0.71, half power 37 Hz. Vented, the same driver reaches 32.6 Hz. The port runs 19.1 m\/s in the channel and 10.7 at the mouth at the 280 W design power, and the cone peaks at 7.9 of its 9 mm. Passband ripple is 3.9 dB and the in-car spread from 25 to 60 Hz 4.4 dB.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eTrunk-load wedge, explained\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThe 20 degree face is the seat side\u003c\/h4\u003e\n\u003cp\u003eA factory rear seat back\n    leans about 20 degrees off vertical.

The floor and the raked back wall\n  are two of its three sides; the third is a single panel bevelled to sit flush against both.\n  It runs across the cabinet, opens into the box at the far end and exits through the side\n  panel: a straight run with no bend, 20.90 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is an isosceles triangle with 5.00 inch legs, 11.7 square inches, running at\n  19.1 metres per second at the tuning frequency. The mouth is that same triangle cut through\n  the side panel with its three edges rounded over at 1\/2 inch, so the opening at the face is\n  20.9 square inches and air leaves it at 10.7 metres per second, against the 17.0 metre per\n  second threshold where a slot port starts to chuff. The panel's throat end carries a 3\/8 inch\n  roundover for the same reason.\u003c\/p\u003e\n  \u003cdiv class=\"df-highlight\"\u003e\n    \u003cp\u003e\u003cstrong\u003eThis enclosure ships dry.\u003c\/strong\u003e Polyfill goes in every sealed Proline X cabinet\n    we build.
