I'm sure your mods helped a bunch... the Battery BAM is (obviously) built to a certain price level and to have certain features (like the choice of the external raw feeder power supply used because of its performance, cost, and ability to work on any world wide line voltage), but it is interesting to see what you can make of it if you want to spend the time and dollars. :-)
@sstalwar
My customers set-up with the subs is very unique and because of the (huge) room size/acoustics (for ex, the room is easily 3x of yours volume wise) and the subs in use, the positioning of the speakers and subs (even if I had those measurements) would not be of any use to you or anyone else. Most likely, both pairs of preamp outputs are in parallel in your preamp and are both active at the same time.
Berning's Tube BAM is his design... probably only Dave Berning has any idea of what the circuit/schematic is ... With enough time and money, anything is possible and can be built (i.e. a tube BAM), but I think has dgarretson has shown - some mods/improvements to what folks currently have in their hands is probably a more reasonable way to go.
