While I did take a serious look at the Selenium offerings a few years back, I never tried them. My primary interest was their compression drivers. The only thing I rmemeber was some very strange anomolies in the impedance chart, primarily two seperate and distinct impedance spikes, which really puzzled me. Ultimately, I went with Eminence gear. I haven't tried any of their stuff.Is the setup you are describing going to be used for bass guitar?
