No fingerprint is the same, we apply this basic concept when designing the perfect enclosure. Subwoofers are all different in size, tone, shape and more; so why should your enclosure be "One Size Fits All"? The answer is it shouldn't. Because we 100% handcraft our boxes, there is not a subwoofer on the market that we cannot match with the perfectly designed box. So if you dont see your subwoofer's specifications on an enclosure already listed on the website, dont sweat it. Call (765) 421-5821 to find the perfect fit.
