I was gonna say, they aren't really in the same class, the RF Punch HE is the low end, the HE2 is more comparable, but I don't have an opinion on the perfects, I hear they are a great SQ sub, I have the HE2 and I love mine, and I've never seen one blown. And I've run more than 400W RMS to it. (It's rated for 400W RMS). Not to take anything away from Euro, he knows just as much about this as anybody does. I'm just saying that sometimes a speaker blowing can happen for alot of user related reasons, ie poor tuning, severe overpowering or underpowering, wrong enclosure volumes. For what you showed though the perfects are better.
i actually dont know a ton about subs, but i know ive blown 3 he2s. my amp is a mtx61000D its a class d amp rated over 1000watts. i paid around 650 for it wholesale back in the day, its gotten cheaper since then still a great amp. i just cant find affordable subs that dont blow. im going to just get a 13.5" jl audio w7 and put a whole in the wallet soon
