I've owned several pairs of this line, and have refoamed 3 pairs of the Titans, Atoms and a V1 pair of Phantoms.
The best part of these speakers is the tweeter. The bass is so bloated and non-accurate that I could not used any of them today as the boxes have waaaay too much resonance. The Atom has little bass below 80 Hz.
If you are looking at a 3 version or newer, in my area they seem to go for $70 and up. That's really close to the sale price of the Pioneer SP-BS22, which with only a 4 inch driver is easily superior to the old Performance line. Get yourself a brand new pair of speakers and you won't have to worry about foams or previous abuse.
