This iKRX-1 is a 2/3 way crossover with all RCA connectors and external power supply. It's currently set up as a two-way with a 133Hz crossover point. 133Hz is a nice spot for sub integration. Rated 7/10 for age only. No box, no manual, no remote. Absolutely no rack rash and a very attractive face.
These are remarkable units that have truely stood the test of time. In every setup that I've had my system has always soundeed better with the Krell in the chain than out. I even preferred them over the pair of PASS XVRs that I had. They also have enough gain that theiy pair well with a passive pre.
