very true anyone that knows what they are doing that uses that much gear will make the room explode. I have been building up a sound system- I have all the knowledge and have done lots of research on my speakers- I use jbl 2241h drivers same as the srx but much different boxes- I havent heard any other boxes compare to the ones i made except maybe servodrives _ I am far from what the valve system is but I can tell you if you know what you are doing it wont take much to knock a wall down :> http://groups.msn.com/lethaltrancefusion/rave.msnw
