I have just ordered a pair of sub-woofers from a private low-yield speaker
and electronic manufacturer in New Jersey.  Each is about a 2-foot cube.
With all the internal baffling and channeling, the speaker (actually a 
self-made 15-inch woofer) produces an effective horn length of 38 FEET !
This speaker can be driven to as low as 2 Hz !  This is not a low peak, 
but has actually driven pink noise at 2 Hz for short periods of time.
This set-up has forced the maker to re-inforce his listening room.
