Proline X PO 10D-S W GUS | Dual 10" Sealed Wedge Subwoofer Enclosure | Built for ResoNix GUS-10

Proline X | Performance Optimized Wedge Two GUS-10s, Each in Its Own 0.60 Cubic Feet. A dual chamber sealed wedge cut for the ResoNix GUS-10 and nothing else. It sits in the trunk with the tall face against the back of the rear seat and the drivers firing rearward, using the length of the trunk instead of standing in the middle of it. 0.60 CU FT NET PER DRIVER DUAL CHAMBER QTC 0.715 TRUNK MOUNT, REAR FIRING 1000W RMS COMBINED BUILT IN TULLAHOMA, TN Read This First This Is Not a Down Fire Enclosure The wedge works in one orientation: tall face flat against the rear seat back, taper running out toward the trunk lid, drivers firing rearward. There are no feet, no baffle clearance gap, and no down fire option on this cabinet. It is cut direct fit to the GUS-10 at a 235.3mm opening. A standard 10 will not fit, and would not see the correct airspace if it did. Built Backward From One Published Number ResoNix specifies 0.60 cubic feet of net acoustic airspace per GUS-10, the volume that produces a maximally flat sealed alignment. Each chamber here is built at 0.63 cubic feet gross. Subtract the driver's 0.031 cubic feet of displacement and each GUS-10 sees 0.599 cubic feet. That is not close to the target. That is the target. Total gross volume across both chambers is 1.26 cubic feet, 1.198 net acoustic. Why a Wedge Packaging It Uses the Trunk Lengthwise Tall face against the rear seat, tapering down as it runs out toward the lid. The cabinet claims the deep space at the base of the trunk and gives height back where the lid closes, so you keep usable trunk. Loading The Trunk Is Part of the System Firing rearward means output loads into the trunk volume and reaches the cabin through the rear seat and deck. That path is what gives a trunk mounted subwoofer its weight. Localization Harder to Point At Because the drivers do not radiate straight into the cabin, the low end arrives through the structure rather than as a beam from behind your head, which makes keeping the stage forward easier. Separation Two Sealed Chambers A full divider gives each GUS-10 its own airspace. Neither cone loads against the other, so the pair stays predictable when both are working hard. Dual Chamber, Not Common Chamber Each GUS-10 loads into its own sealed 0.63 cubic foot chamber, isolated by a full divider. With separate chambers, one driver's cone motion does not modulate the air load the other driver sees, so the two stay acoustically independent under hard excursion. The GUS-10 is rated at 500 watts RMS each in its suggested enclosure, so this cabinet is built around a 1000 watt pair. A single Proline X terminal cup is side mounted and pre wired with 12 gauge OFC. This is a raw enclosure, so how you wire the drivers from that cup is your call. How It Is Built Cabinet Cut on our ShopSabre CNC from Langboard Elite MDF and assembled with dado and V groove joinery over 0.75 inch panels, with a double baffle at 1.5 inches and a full chamber divider. Angled panel meets are cut as V joints so the faces close on a machined bevel rather than a filled seam. Mounting Pattern The GUS-10 is in the Proline X CAD library, drawn from the manufacturer's own STEP file. The 235.3mm cutout and the nutsert locations are machined in the same operation from the same origin, so the holes cannot drift relative to each other. 8/32 threaded inserts installed at both driver positions with stainless machine screws supplied, matched to the driver's 256mm bolt circle and its eight 6.3mm holes. Wiring and Damping One Proline X ABS and carbon fiber composite terminal cup, side mounted, pre wired with 12 gauge OFC to both driver positions. Polyfill is installed as a light wall lining to control internal reflections without altering the acoustic volume, because adding fill density would shift the alignment off the 0.60 target. Finish Plush black carpet with a black acrylic badge on the woofer face. Fitment External dimensions are 30.25 inches wide by 13.5 inches tall, with depth running 12.25 inches at the base tapering to 7.35 inches at the top. Maximum driver mounting depth is 6.5 inches, comfortable for the GUS-10's 101.5mm requirement. Front clearance. ResoNix specifies 23mm minimum clearance in front of each GUS-10. At 18mm of Klippel verified one way excursion that is the operational envelope of the suspension, not optional headroom. Since the drivers fire rearward into the trunk, anything you load behind the box has to stay outside that envelope. Verify both positions independently. Enclosure Performance Calculated from ResoNix's published Klippel measured parameters for the GUS-10 D4 coil: Fs 16.91 Hz, Qts 0.35, Vas 53.78 litres. Nothing here is estimated.

Anechoic half-space, no cabin gain. 0.60 cu ft, this enclosure 0.35 cu ft and 0.90 cu ft Look at the F3 column, not the Qtc column. Across the entire usable range, from ResoNix's minimum 0.35 up to their maximum 0.90 cubic feet, F3 moves by less than two hertz, and the largest box is actually slightly higher than this one. Enclosure volume on this driver changes the shape of the response, not how deep it plays. That falls straight out of a 16.9 Hz Fs paired with a 0.35 Qts. Why not build bigger. On the GUS-10 the largest recommended volume gives up damping and control without buying a single hertz of extension. F3 at ResoNix's 0.90 maximum is 34.8 Hz against 34.2 Hz here. You would be trading a maximally flat alignment for an overdamped one and getting nothing back. Run your own numbers with the Sealed Box Calculator.
