+12 db @ 40hz is a dangerous setting for your gear. At the low end of system bandwidth, +6 would be the most I would attempt to use. And then for playback (recorded music) only where things were controllable.
Hey i will try tomorrow (when neighboures are awake) to test with 40Hz 0db.
Today i put one sub horizontal at the ceiling....WOW what a difference in sound!!! the other is still standing in front of the bar(facing eachother) but planning on hanging him also this weekend.
I was also playing with the tought to get an extra EX4000 and run them both bridge each at 1 speaker to get more headroom... really the sound is really ok now but running cliplights kind of fast (beacouse of the +12db... ? )
love to hear your toughts
