Unlock the full potential of your subs with the ProBuilt S12 Enclosure – a premium subwoofer box engineered for serious performance. Designed to house one 12" subwoofer, this enclosure delivers a powerful combination of tight, accurate bass and ground-shaking lows, whether you're cruising the street or competing in the lanes.

Backed by nearly 20 years of hands-on experience, the ProBuilt S12 is more than just a box – it’s a performance upgrade. Every element has been fine-tuned through real-world testing and precision craftsmanship. From internal airspace to port tuning and geometry, this enclosure is optimized to make any 12" Sub sound its absolute best.

Featuring our proprietary ResoGuard Anti-Resonance Geometry, this enclosure is engineered to break up internal standing waves and eliminate modal distortion.
