Starr Mountain Sound is the place to call on when you want a custom built enclosure for your subwoofer. You see that's our specialty here at Starr Mountain. We have been building custom designed boxes since the 1980s. We don't shortcut on the boxes or skimp on materials. All of the enclosures built here will consist of 3/4" MDF or plywood (customer choice) and the enclosure itself will be glued, screwed, properly braced and sealed. Pre-fab boxes are normally glued & stapled and that just doesn't cut it for us here at the Mountain. Give us a shout when you are ready for a truly strong and loud enclosure. Unleash your subs full potential today. We ship enclosures anywhere in the U.S. so give us a shout about yours.
