Performance Optimized Down Fire Wide Sealed Dual 10" Shallow Sub Enclosure Wavtech thinPRO10 · Dual 10" Sealed enclosure

Because it is only 12 inches deep. Our standard Performance Optimized Down Fire cabinet for this driver is 30 wide by 15 deep, and this one is built for spaces three inches shallower than that, typically under the rear seat of a truck or SUV or on a narrow cargo floor.

Airspace has to come from somewhere. Losing depth means recovering it along the length, so the cabinet runs 41 inches long and stands 5.9375 inches tall, and still keeps each driver in a properly sized separate chamber. If your space is wide and shallow rather than deep, this is the shape that works.

Same driver, different shape. The standard cabinet is 30 by 15 by 6.25 inches and holds 0.39 cubic feet net per driver. This cabinet is 41 by 12 by 5.9375 inches and holds 0.395 cubic feet net per driver.

That is effectively the same airspace, so acoustically the two are interchangeable. Choose on the space: with 15 inches of depth the standard cabinet is the pick; if depth stops at 12 inches and you have 41 inches of run, this one fits.

Both thinPRO10 variants are single voice coil, so there is no coil configuration decision at the driver. The enclosure uses one side-mounted Proline X terminal cup with a single pair of posts, pre-wired in 12 gauge OFC to both driver positions in parallel.

A pair of thinPRO10-2 drivers presents 1 ohm at the cup, and a pair of thinPRO10-4 presents 2 ohms. Use two of the same model and confirm the resulting load against your amplifier's minimum stable impedance before powering the system.

Each chamber holds 0.395 cubic feet net. With the thinPRO10-2 that gives Qtc 0.873, Fc 49.2 Hz, F3 41.6 Hz, and with the thinPRO10-4 it gives Qtc 0.825, Fc 50.8 Hz, F3 44.5 Hz.

Wāvtech's preferred box is a 0.35 cubic foot chamber, so this cabinet sits a little larger and a little better damped than their target. Those figures are anechoic; cabin gain adds real output below 50 Hz in a vehicle.

Wāvtech rates each thinPRO10 at 750 watts RMS with 2250 watts peak and recommends 250 to 750 watts per driver, so up to 1500 watts RMS total across the pair. Aim for the upper half of that range.

Sensitivity is 81 dB on the -2 and 82 dB on the -4, which is low. That is the tradeoff for packing a 4.5 inch coil and 20mm of excursion into a 2.875 inch frame, and underpowering leaves significant output unused.

Side mounted, and there is one cup serving both chambers rather than one per chamber. Every Proline X Performance Optimized enclosure uses a side mounted terminal cup regardless of alignment, whether standard, wedge, or down fire. On this cabinet that keeps the connection fully accessible with the enclosure in its installed position, since both baffles face the floor. The cup is our Proline X ABS and carbon fiber composite unit, recessed, with stainless hardware, copper ring terminals, and pre-wired 12 gauge OFC.

V-groove and dado joinery, CNC-cut on ShopSabre routers from Langboard Elite MDF, with every joint machined to lock mechanically before adhesive goes on, which keeps both chambers airtight under sustained pressure cycling. The chamber divider is a full-height bonded 3/4 inch panel, which also ties the front and rear walls together across the 41 inch span.

Front baffles are a 1.5 inch double layer at both driver positions, with the outer layer machined as a flush recess so each driver bolts to the inner layer. Corners are square, polyfill is installed as a light wall lining in each chamber, and the 1.75 inch standoffs ship uninstalled. Assembled and inspected in Tullahoma, Tennessee.

No. This listing is for the enclosure only. Bring your own pair of Wāvtech thinPRO10-2 or thinPRO10-4 subwoofers, two of the same model. The cutouts and mounting depth are direct fit at both driver positions.
