I have owned a pair of theeese for 5 years and am now replacing one due to a bad coil (i think i pushed it too hard... hehe). i have definately got my moneys worth and am over-all verry impressed with the performance of my subs especially with the low end bass witch is what i really like the best, i would reccomend theese to anybody who likes head squishing bassfor small dough.
I bought one of these 10s off of eBay to put in my car after my nice big system got stolen and before I had the money from insurance to get another nice system going. with a 250.2 RF amp, and in a 1 cube sealed box with some polyfill in it, it played more like a fairly decent (except sub-35 hz, naturally) 12 rather than the cheap 10 that it really is. I'm speaking in terms of cost, not quality.
I got a set of these subs from a buddy. I put them in a ported Audioformz fiberglass enclosure with an an Alpine MDR350 amp they hit so hard I cant see straight!
i have a lightning audio 650 watt amp, and 2 10s i mtx and the lightning i didnt believe in cheapo stuff till i hooked these to lightning products up i am buying one more they hit hard and take abuse
