At Bassheads Entertainment, a large part of what we do is offer Custom enclosures and designs for all types of subwoofers, in many different applications.  If you're just looking to add a little bit of bang in the back with a set of tens, or cause some serious damage with a few eighteens, rest assured you are in the right place.  Take a look around, and if you don't see what you are looking for, just shoot us an email detailing what you are looking for, and the staff will get back to you quickly.
