I have a set of Kappa 9a's which have resolved the amp eating issue. The a stands for a filter for the very low frequency that sets the stage for the low impedence amp killing problem. I have used the switch when running from my Yamaha unit but omit switch use when driving with Adcom monoblocks. If you are lookin for Kappa 9's you might as well inquire about the 9a's. They were the last year model before being discontinued. A great speaker.
Infinity Kappa 9's
Working overtime trying to get a pair of kappa9's. Heard my friend Traci's and for the past 2 years I have been trying to corral a pair and I think I'm finally gonna get'em (fingers crossed!). Traci sez he burned up (literally) 2 carvers and 2 B&K's that would shut down if he played certain types of music kinda loud. He know runs 4(!!!) Parasound HCA-1200's. Am I uninformed or is this a bit much. It sounds great to me (I did'nt hear the B&K's) but am I gonna have to do something like this to satisfy a pair of 9's?? Starting to rethink this but DAMN they sound good. What should I do??
