18" Kicker SoloX Subwoofer Enclosure – 7.5 cu ft Net, 28Hz Tuning, 1" MDF, 2.5" Top Baffle, Heavy-Duty Braced, Up-Fire with Front Slot Port

Built for the monster Kicker SoloX 18" subwoofer.
This enclosure is engineered to meet every requirement Kicker calls for: correct 7.50 cu ft net internal volume, 28Hz tuning, accurate port area, and a structure built to handle the brutal power and excursion the SoloX series is known for.

The enclosure features all 1" MDF construction with full internal bracing, plus a massive 2" thick double-laminated top panel to control flex when the SoloX moves air. Your woofer sits inside a precision-cut inset mounting lip, giving it a recessed fit for improved aesthetics and added baffle strength.

The design is up-firing for maximum loading in SUVs/trucks/vans, with a large front-firing horizontal slot port tuned exactly to Kicker’s recommended spec.
This isn’t a generic 18" box — it’s purpose-built specifically for the SoloX platform.

Every enclosure includes our Atrend Supreme Terminal Cup, featuring gold-plated binding posts supporting banana plugs, bare wire, or spade lugs for high-power, low-loss connection.

This is the definition of a competition-ready, USA-built heavy-duty enclosure.
