Just check my signature. I use electrostatic mains with transmission line sub woofers.
Unlike many esl's Acoustats will play quite loud. They are rated to produce 110dB at 18' in a 14'x22' room. I have measured +106dB with my old Rat Shack meter at the sweet spot. The maximum my old meter reads is 106dB. It was actually louder because the needle was bouncing hard off the 106dB stop.
