I have had Xrs for about a year, maybe more, and have gone through a few amps, looking for what OI want to stay at, first it was PG Ti500.4 and 75w rms(maybe lil more, it's PG Ti) then PG X100.2, with 108w rms to each side, then some old Kenwood KAC-929, with I believe 150W each, and Xr650's seem to like this type of abuse. The only problem, I got sick of the brighter tweeters, and I replaced them with SSCS6's tweeters, and that helped out a lot. from about 55-60 hz all the way to about 200hz, I think these speakers rock, it's just too bright for me. To each his own, i guess.
