I have 4 9v.3s that I'm thinking of using for my subs for my surround sound. Unsure of what size enclosure and tuning for this application. Any suggestions?

4 8s in a 3 cubic box tuned to 20 or 25 hertz should be a good box for HT. Are you looking for a box design?

I have a huge built in entertainment center that takes up a whole wall in my living room. The top is shelves and the bottom is a large cabinet. I'm thinking of building an enclosure inside one of the cabinets and where the oval shaped pieces are between the cabinet doors pulling them out and putting in some of the cinema speakers in. Measurements are in my favor. Ignore the baby debris.
