Mike, I've been reading some old threads on AVS and have captured some notes, I will try to add them this evening. In general, most of the complaints talk about sibilence or you hear a lot of Ssssss in multichannel music using the 150. The issue of having multiple tweeters spread out like the current 150, older models had a different alignment. No other mfg does this in a center, which caused comb filtering and other issues. Mainly I see how people say it just does not match the same sonic signature as the other Axiom speakers. You always hear about the front 3 should match, well a lot of people say the VP series matches none of the other Axiom speakers which affects the timber matching. I will see what I can add from my notes, however, I want to be cautious not to bring up old issues that have been resolved with V2 and other updates over the last few years.
