Thanks for the input. It looks like the only way I can squeeze this into their budget is to buy used. The QSC amp might be a good bet, but the specs say it is only good into 4 ohms (correct me if I'm wrong). The speakercraft amp is another option, but well over the budget I have for these. If I go used, any recommendations on places that are reputable (as opposed to eBay and that sort of thing)? Pro amps tend to suffer a lot of abuse already, so buying used is lot more risky. Adcom would be nice, but I don't know how well they would handle a 2 ohm load. And older NAD maybe, since they have decent protection circuits?

Regarding the bass, that's something that I can tell them, but eventually someone, at some point is going to turn up the bass, so I need an amp that can handle it. Sound quality isn't really an issue, especially with all the ambient noise in the exercise room. Maybe I can find an old sub that we can pass the signal through at a later date, but for now this is what it is. Yes, Klipsch speakers would have been better, but they're not going to swap out these speakers.
