"JBL 305 and it was all high end and reminded me of the old piezo tweeters from long ago."
The LSR305 has HF and LF trim controls. I'm guessing that the "expert" at Guitar Satan had them set up improperly (like - backwards

). Just a guess, although a GS expert "tested" a pair of my PA speaker tweeters with a 9-volt battery last week, and probably blew them up. You test
woofers with a 9-V, not tweeters.
The KRKs are good speakers, but the JBLs are getting some killer reviews.
