The Paradigm Active line has been discontinued. The resources vs. profit equation just didn't work out. Four mono blocks a pair of electronic crossovers and speakers for $2000 along with the fact that audiophiles don't buy active speakers and non audiophiles don't spend $2000 on speakers. They were great speakers, it is too bad more audiophiles did not think of them as worthy for consideration. I got my Active 40's just in time, thank god
