Performance Optimized Down Fire Wide Sealed Dual 10" Shallow Sub Enclosure ResoNix GUS-10 · Dual 10" Sealed enclosure

Because it is only 12 inches deep. The standard Performance Optimized Down Fire platform is 30 wide by 15 deep, and this application needs a cabinet that fits a space three inches shallower than that.

The airspace has to come from somewhere, so the cabinet runs 41 inches long instead of 30 and stands 7.8125 inches tall, with each driver still in its own chamber. If you have 15 inches of depth, the standard cabinet is the pick; if your space is long and shallow, under a rear bench or on a narrow cargo floor, this is the shape that fits.

The standard cabinet is 30 x 15 x 8.3125 inches and gives each driver 0.60 cubic feet net. This cabinet is 41 x 12 x 7.8125 and gives each driver 0.607 cubic feet net, within 0.007 cubic feet of the standard box. Acoustically they are effectively the same enclosure. The choice is about shape: the standard box needs 15 inches of depth, this one needs 12 inches of depth and 41 inches of run.

The chambers are sized to ResoNix's own 0.707 volume for the Dual 4-Ohm. At 0.607 cubic feet net per chamber: Dual 4-Ohm: Qtc 0.686, Fc 38.3 Hz, F3 39.5 Hz. Dual 2-Ohm: Qtc 0.602, Fc 36.0 Hz, F3 43.4 Hz. The Dual 2-Ohm is designed around a smaller box, so it lands more damped here.

Those are anechoic figures. Firing into the floor, the sealed rolloff meets rising cabin gain, so in-car response runs deeper than the numbers above.

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. You do not wire the two chambers separately at the amplifier.

Final impedance is set at the drivers. Each GUS-10 is dual voice coil, so how you wire the two coils on each driver determines the load the amplifier sees through the cup. Use two of the same coil version, wire them identically, and confirm the load against your amplifier's minimum stable impedance. Hold delivered power to 500 watts RMS per driver.

Because ResoNix specifies a minimum clearance in front of the cone, and on a down fire enclosure the thing in front of the cone is the floor. Their requirement for the GUS-10 is 23mm between the surround and the obstruction, or 55mm measured from the baffle surface.

The custom-fit standoffs hold that clearance at both driver positions. They are a required part of the design, not an accessory.

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, and on a down fire cabinet that keeps the connection accessible with the enclosure installed, 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 12 gauge OFC pre-wired to both driver positions in parallel.

V-groove and dado joinery, CNC cut on ShopSabre routers from Langboard Elite MDF. Every panel joint is a machined interlocking groove that mechanically locks the panels before adhesive is applied, which keeps both chambers airtight under sustained pressure cycling. Corners are square, the Down Fire series standard, with no radii.

The front baffle is a double layer at 1.5 inches, with the outer layer machined as a flush recess so each driver bolts to the inner layer. A full-height bonded 3/4 inch divider separates the chambers and ties the front and rear walls together across the 41 inch span. Custom-fit standoffs are included to hold ResoNix's required floor clearance. Polyfill is installed as a light wall lining. Assembled and inspected in Tullahoma, Tennessee.

No. This listing is for the enclosure only, and includes the custom-fit standoffs. ResoNix GUS-10 subwoofers are purchased directly from ResoNix Sound Solutions. The cutouts and mounting depth are direct fit at both positions; use two of the same coil version.
