the 500 watt twelve in JL's mainstream line, a 26.7 Hz motor with a 0.44 Qts and 80.5 litres of Vas. The wedge gives it 1.51 cubic feet net vented at 32 Hz through an 18.4 square inch port, in a cabinet 30 inches wide, 15.5 tall, 8.88 inches at the top and 14.52 at the base.\u003c\/p\u003e\n  \u003cp\u003eA 0.44 Qts rolls off early, so the anechoic F3 is 35.1 Hz, and the in-car curve is where this driver is judged: 1.25 dB of spread across 25 to 60 Hz at 32 Hz tuning, on 1.20 dB of anechoic ripple, the flattest passband of the JL twelves. The port takes 24.79 of the 25.43 inches available and runs at 19.1 metres per second in the channel against a 19.3 limit, 11.9 at the mouth.\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, 24.79 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is an isosceles triangle with 6.25 inch legs, 18.4 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  29.5 square inches and air leaves it at 11.9 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. It does not go in this one.
