Your Subwoofer Box Specialist 
At CustomLowZ, subwoofer boxes aren’t just something we do—they’re all we do. Every enclosure is designed in-house, handcrafted in the USA, and built with premium materials for unmatched performance and durability. Whether you’re after a precision-tuned ported box, a thunderous 4th order bandpass, a space-saving truck enclosure, or a convenient flat pack kit, we’ve got you covered. Choose from our expertly engineered pre-made plans or go fully custom to match your exact specs. If it’s about bass, it starts here.
