Yes, if the replacement speakers are each 60-70 (180-210) then it's worth considering a new VP150. However, I also have a pair of M22's and QS8's of the same vintage as my current VP150. If I mix a new VP150 v3 with the other speakers, will there be any noticable difference?

I guess I'm asking what is different between the original VP150 and the newer v3 speaker? How much of an improvement has there been in the last 8-10 years?
