Dear Sir;
I own a 24 box KP 600 system and if you need some info e mail me at jophise@comcast .net as i have info on this system. The system was very expensive to build an is made of fiberglass and mylar over a balsa core. the sub and low cabs are tuned above and below their resonant frequency.
Klipsch at one point I believe lost money on each sale. But I can tell this is hands down the best sounding arena system ever made, even to date!!!! The detail in the mid high at low volume and at earbleading levels is just amazing. To bad the powers that be at Klipsch desided that they did not want go forward with updated designes because there were many, based on the input from RAM Sound in Florida and myself Northeast Sound in Massachusetts. Hope I can help you.
Joey B KP600
