NVX's 8 inch at 39.1 Hz, a Qts of 0.39, 6.0 litres of Vas and 400 W RMS. This cabinet gives it 1.15 cubic feet net behind a 2.25 inch three-layer baffle, vented at 34.0 Hz through a 18.8 square inch slot beside the woofer, for an anechoic F3 of 28.9 Hz in a 30 by 14 by 11.0 inch front-firing box.\u003c\/p\u003e\n  \u003cp\u003eSealed, the NSW8v3 needs 0.09 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 480 W, 1.2 times NVX's rating: the channel runs 20.5 m\/s and the mouth 11.4, and the cone peaks at 8.5 of its 10.5 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 5.75 inches along its wall and turns once along the back wall for another 19.58 inches, which is why a 34.0 Hz tuning fits a 11.00 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eThe NSW8v3 also builds in the Performance Optimized ported down-fire, the smaller and cheaper box.

The N-Series manual does not say whether that Xmax is one-way or peak to peak; we read it as one-way, the way NVX labels the VC and VS figures, and keep power at NVX's own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eThe numbers to respect\u003c\/h3\u003e\n  \n  \u003cp\u003eSet a 27 Hz subsonic filter, 24 dB per octave.
