Xmax is 23 mm one-way. Cone area is 124.65 square inches, which is where a 15 earns its keep: it moves the same air as a 12 at roughly two thirds the excursion, so it stays inside its linear range on program material that would have a smaller driver working hard.\u003c\/p\u003e\n  \u003cp\u003eIt ships in two coil configurations. The VCW152v3 is dual 2 ohm, the VCW154v3 is dual 4 ohm.

The woofer is mounted on the vertical face that sits at the back of the box, closest to the trunk lid, and fires rearward into the trunk cavity. The angled face is on the opposite side, the side that faces the front of the vehicle, and tucks against the rear seat back.\u003c\/p\u003e\n  \u003cdiv class=\"po-grid\"\u003e\n    \u003cdiv class=\"po-card\"\u003e\n      \u003ch4\u003eSeat-Side Face Matches Seat Lean\u003c\/h4\u003e\n      \u003cp\u003eMost factory rear seat backs lean roughly 20 degrees back from vertical.

A box built to 2.0 gross gives the driver 1.85 after displacement and lands system Q at 0.78. Built to 2.0 net it lands at 0.76. Both are usable, but 0.76 is the flatter of the two and it is the one NVX's stated volume actually describes. That is the band between maximally flat and lightly punchy: a small amount of midbass weight, no overhang. Opening the box out to 2.6 cubic feet drops Q to 0.70, maximally flat, at the cost of midbass authority a 15 has no reason to give up. Coming down to 1.44 pushes Q to 0.85 and starts putting a bump at resonance.\u003c\/p\u003e\n  \u003ch3\u003eAlignment Numbers\u003c\/h3\u003e\n  \u003cp\u003eTarget System Qtc: 0.76, the same for both coil variants. The two coils differ slightly in free-air resonance, so the corner differs with them. VCW152v3 at Fs 29.30 Hz: Fc 49.5 Hz, F3 46.3 Hz anechoic. VCW154v3 at Fs 31.30 Hz: Fc 52.8 Hz, F3 49.4 Hz anechoic. In a sealed trunk-load install, cabin gain typically adds usable output an octave below the anechoic F3.\u003c\/p\u003e\n  \u003ch3\u003eMounting Geometry\u003c\/h3\u003e\n  \u003cp\u003eThe vertical trunk-lid-side baffle is CNC-cut to 14.25\". NVX lists 14.125\" in the VC-Series v3 manual and 14.21\" on the product listing, so we cut to a figure that clears both and still leaves a quarter inch of flange bearing against the driver's 14.78\" mounting diameter. Mounting depth required is 8.19\", and at the cutout centerline the cabinet gives 10.53\" of internal depth behind the 1.5\" baffle, so there is roughly 2.3\" behind the motor once the wedge taper is accounted for. 8\/32 threaded inserts are pressed into the baffle backside for secure driver retention.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n  \u003ch2\u003ePerformance Series Construction, Driver-Specific Tuning\u003c\/h2\u003e\n  \u003cdiv class=\"po-grid\"\u003e\n    \u003cdiv class=\"po-card\"\u003e\n      \u003ch4\u003eLangboard Elite MDF\u003c\/h4\u003e\n      \u003cp\u003ePremium 3\/4\" MDF panels milled to documented spec, denser and more dimensionally stable than commodity MDF.

Series wiring gives 4 ohms, parallel gives 1 ohm. Run it in series at 4 ohms unless your amplifier is genuinely rated 1 ohm stable, because a lot of amps that advertise 1 ohm operation are rated for it in mono at a duty cycle no one actually runs. The VCW154v3 is dual 4 ohm and is the easier load: series gives 8 ohms, parallel gives 2 ohms, and 2 ohms is where most monoblocks make their rated power without complaint.\u003c\/p\u003e\n  \u003cp\u003eTarget 1050 to 1500 watts RMS at your final wired impedance against the driver's 1500 watt continuous rating. Set gains by ear or with an oscilloscope at the level you actually listen, not at the level the amp will make. With 23 mm of one-way travel this driver will take mechanical abuse long after the coil stops appreciating it, so the failure mode here is thermal, not mechanical.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n  \u003ch2\u003eBuilt in Tennessee, Backed by Audio Intensity\u003c\/h2\u003e\n  \u003cp\u003eManufactured in Tullahoma, Tennessee on our ShopSabre CNC equipment.
