Hi Everyone, My rant for the day. After many trials and tests and retrials I concluded that T & S were right. It is really difficult to get 25HZ from a 1 cubic foot box. I tried and finally gave up and settled for about 35 HZ. I guess it is back to my 7.5 cubic foot boxes with the 15 inch subs.... they get 25 easy.

Hi Again, after much frustration.... I put the two 7.5 cubic footers back into the system. Things are a shaking and moving again. It is really surprising how much sound actually is below 50HZ. Good thing two walls are plasterboard over brick and the floor is tile (with lots of rugs) over concrete.

Hi Wayne, Yes. Now I do have a pair of 15 subs designed for infinite baffles...I wounder how the chimney would work as a transmission line. Let's see 3 foot wide, 2 deep and about 20 tall.
