Thanks Wayne. I'm patiently saving to get the PI 7s. I'm moving to a new house next week and once I'm settled I'll go for the kit and build my cabinets. I'm presently using a Fostex based backhorn (EZ 168). I think the PIs will give me the efficiency of a horn, more higher extension and deeper bass than what I have right now. In short, improvement in all aspects. Can't wait. You'll hear from me soon.
