Does anyone know where the 2 bass panels crossover to the mid panel? Have a pair of these in a new house and I am wondering if I can replace the 2 bass panels with an ob servo sub to save some space...Thanks.

The basses are rolled-off by about 18 dB/octave at around 250 Hz. The mids have a cut-off by 12 dB/octave at 400 Hz. Must subs are designed to work below 80 Hz or so. You need some special drivers that can cover the range up to the mids and I think you want at least two subs.
