At one time it was recommended that if speakers face each other, the polarity should be flipped on one of the speakers. 
Don,

Whoever recommended that is wrong, unless one driver has been mis-wired, or put in backwards.

Those SRX725's if working properly and powered up right should all but blow that room apart.  I've seen DJ setups with 4508 dual 15's loaded with JBL 2205's, powered with BGW 750's with the stacks on picnic tables outdoors that sounded great - plenty of LF.

Do you mean on the graphic EQ everything from 40 to 80 was boosted +12?

If you are in need of more 40hz and lower, why not just fly everything?  Put a mono dual-18 sub in the middle and done.

+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

You'll have to start being more careful when you run a bridged EX4000 per cabinet.

How are you suspending the 725? Do you have the version with the threaded fly point inserts?
