it sounds excellent imo as it is built to specs for that specific subwoofer and would sound the same as any other shape built to the same specs (my side gig of building custom speaker cabinets has turned into a full time plus gig these days).How's the sound?
My Wife asked me if I wanted a bigger TV and I said sure. The old was a 70" the new one is a 86". The credenza was a result of the feet on the new TV being 70" apart and the old TV stand only being 5' wide. On the plus side building it shorter overall helped with the viewing angle.
