Axiom Home Page Forums General Discussion Advice from Axiom Owners Upgarde question

I have M60ti in my home theater and am still very happy with them - personally would not bother updating to v4 unless I was also using them as my primary stereo music system. My first recommendation for upgrade would have been getting a VP180 but you have already done that.

On the other hand "more sub" often gives a tangible improvement. Maybe a bit less in your case because EP500 won't be overdriving and making that awful "grunk" noise because of the DSP, but if your room is big (and I think 16x20 counts as at least middling-big) then more sub is going to help.

I really like the M5HP and actually traded a pair of M60v4's for a second pair of M5HPs. That said, I doubt the M5HP will play at the same levels as M60 in "large" mode although it's possible they could if you already run the M60s in "small". The fact you were clipping the amp on the M60s suggests "large" though.
