At Basshead Supply the goal with the “branded series” enclosures is to offer subwoofer specific enclosures that are well built, well performing and good looking enclosures at an affordable price. Using premium 1” Baltic Birch all around we are able to achieve a very strong and light enclosure.

The entire enclosure is glued together with Titebond III and coupled with our 1” baffle and an additional 24mm baffle brace (on the dual subwoofer models) the enclosure is strong enough to handle high power subwoofer setups. Finished off with our carbon gray stain and a polyurethane finish these enclosures have a unique look to set it apart from all the generic prefabs.
