The Precision Engineering Difference
A 6th order bandpass design uses two ported chambers. We model their volumes, port dimensions, and tunings together for your subwoofer specifications and listening goals. This layout can support strong output across a useful bass range, but requires sufficient space, accurate construction, and appropriate protective filters.

Fantastic design with well illustrated plans from just about every angle of the enclosure. I am a professional woodworker with all the necessary tools to make slight adjustments on the fly pretty simple. The only thing I would have liked to see is maybe a quick explanation of why certain features of the enclosure were designed, such as port locations, and subwoofer orientation. That way it would be clear if any adjustments made to the design would be either no big deal or catastrophic. But all in all a great design
Hunter absolutely delivered as usual. Always a great design, exactly what we were looking to build.
Box sounds great
I had just built a box by a well known designer a week before getting in touch with ezdb. Sent him the design I got and built. I was told to pretty much get it out of my truck. 2 weeks later get ezdb box finished up and it was exactly what I wanted. Ill never go to anyone else.
Excellent product as always
Fast and easy to work with a phenomenal design thats easy to read and build.
Box has great bandwidth and plays with authority on low power. My subwoofer is only seeing around a third of its rated power so plenty more to go and it'll only get louder. Box plays clean and accurately!
Looks like a pretty impressive build
Best customer service, great price . Highly recommend
