FREQUENTLY ASKED QUESTIONS
Common questions about our subwoofer enclosures.
How do I choose between a ported and sealed enclosure?
Ported boxes are louder and produce deeper bass — best for hip-hop, EDM, and SPL competition. Sealed boxes give tighter, more controlled bass with a smaller footprint — ideal for rock, jazz, and sound-quality builds. Check your subwoofer's small parameters or the manufacturer's documentation for recommendations. Still not sure? Email info@bassheadsupply.com with your setup and we'll point you in the right direction.
Will these enclosures fit in my vehicle?
Product pages list external dimensions for every box. Measure the space you plan to install it in — trunk, cargo area, or under-seat — before ordering. Just as important: measure your trunk opening, door opening, or hatch. Those openings are often the real bottleneck, not the space itself; many enclosures fit the cargo area but can't physically make it through the opening. For truck cabs and hatchbacks, our 8" and 10" enclosures are specifically designed for tighter spaces.
Why use Baltic birch plywood instead of MDF?
Baltic birch is stronger, lighter, and more resonance-resistant than MDF. Our 13-ply and 17-ply panels won't swell from moisture and hold fasteners significantly better — both critical for enclosures handling serious power. MDF is cheaper but heavier, more fragile, and prone to water damage. Every Basshead Supply enclosure uses genuine Baltic birch, never MDF or particle board.
Can I return a subwoofer box if it doesn't fit?
Yes — we accept returns on unused, undamaged enclosures within 14 days of delivery. Buyer covers return shipping. Double-check dimensions on the product page before ordering to avoid this.
