Micro Series 15" Sealed Enclosure | Built for ResoNix GUS-15 Single 15" Sealed enclosure

No. This is an enclosure-only product built exclusively for the ResoNix GUS-15. The driver must be purchased separately from ResoNix Sound Solutions. The enclosure ships pre-wired with the Proline X terminal cup, 8/32 threaded inserts, stainless machine screws, pre-installed polyfill, and rubber feet for downfiring installation. No other driver shares the GUS-15's cutout diameter or is served by the 1.42 cubic foot volume target.

ResoNix recommends 1.35 cubic feet of net acoustic airspace for the GUS-15 to achieve 0.707 Qtc. The GUS-15 has a published driver displacement of 0.072 cubic feet. Building to a gross volume of 1.35 cubic feet would leave only 1.278 cubic feet net after the driver is installed. Below the recommendation. The correct gross build volume is 1.35 + 0.072 = 1.422 cubic feet. This enclosure is built to deliver 1.42 cubic feet net acoustic airspace after the driver is installed, accurately matching ResoNix's target. The 1.42 figure is the net acoustic volume, not the gross box volume.

Both drivers share the same GUS series engineering philosophy, Klippel-verified motor linearity, copper shorting rings, titanium voice coil former, and Nomex/carbon fiber cone. The GUS-15 differs in scale: it has a larger effective cone area (804.25 cm² vs 490.87 cm²), higher Xmax (25.89mm vs 20.69mm), and a higher power rating (1,500W vs 800W RMS). Output capability at any given frequency is a function of cone displacement. Cone area times linear excursion. The GUS-15's combination produces substantially more displacement than the GUS-12, particularly in the sub-30 Hz range where the 15-inch advantage over a 12-inch driver becomes most audible in a well-tuned system.

The GUS-15 at 0.707 Qtc produces a flat anechoic response with the deepest low-frequency reach available from any shallow 15" driver. In a real vehicle cabin, bass frequencies below 80 Hz receive significant gain from acoustic boundaries, which reinforces the driver's deep extension in the listening position. The 15" cone area combined with 25.89mm of Klippel-verified one-way Xmax produces output at 20 Hz that no shallow 12" can match. With correct amplification and crossover configuration, this combination delivers reference-grade low-frequency performance in a footprint that fits behind seats and in cargo areas where a standard-depth 15" cannot go.

The GUS-15 is rated at 1,500 watts RMS. For the D4 wired parallel at 2 ohms, target a monoblock stable at 2 ohms delivering 1,000–1,500 watts RMS. For the D2 wired parallel at 1 ohm, an amplifier explicitly rated for sustained 1-ohm operation at this power level is required. This is a demanding load that not all 1-ohm-rated amplifiers handle reliably under continuous use. Do not exceed 1,500 watts RMS at the rated impedance. ResoNix is explicit that overpower damage is not covered under warranty, and the GUS-15's thermal limits are not inflated the way most competitors' ratings are.

The GUS-15 at 1,500 watts RMS generates the highest sustained internal pressure of any single driver in the Micro Series lineup. Stack-fab construction layers and bonds CNC-cut MDF panels to increase panel mass and eliminate single-layer glue joints. Dowels add a third mechanical element, a pinned connection that resists lateral shear forces at panel joints independent of adhesive condition. At this power level, the combination of stack-fab layering, interlocking dado joints, adhesive, and dowel reinforcement is the correct structural standard for an enclosure designed to hold its geometry and acoustic seal over years of 1,500-watt operation.

Yes. Rubber feet are included for downfiring. The GUS-15 features a vented rear cone assembly that allows the pole vent to be fully obstructed without acoustic penalty. Downfire in a tight install is viable. ResoNix notes that real-world difference between upfire and downfire orientations is minimal for the GUS series; choose based on install practicality and what produces the best vehicle floor coupling in your application. The minimum front clearance requirement of 33mm applies regardless of orientation. Confirm against whatever is in front of the driver in your install.

Every Proline X enclosure is CNC-cut and hand-assembled in Tullahoma, Tennessee on ShopSabre CNC routers. Langboard Elite MDF is used throughout, named, mill-documented, with published density, internal bond, and screw-holding specifications. Internal volume, cutout geometry, dado joint depth, baffle layer count, dowel placement, and terminal positioning are all held to spec on every unit. Proline X is the enclosure brand owned and manufactured by Audio Intensity.
