Can this design be modifed for home theater application? Do you offer design services? I would like something like this tuned to around 16hz

Has anyone made this box yet? I have 2 b&c 21sw152. Or just stick to 2 bass reflex designs.

Are these 2 21" used in push pull or in push push mode? Are they in phase - both positive going or 180 degrees polarity to push pull? Or do they need to be precisely time aligned to work in this box?
