Budget system for Rock and dance Music?

Cerwin Vega 215's are excellent for dance music and stuff like that. I don't know what the current version is, but they sell for like $600+. I wouldn't buy them used, as the types that go for this type of speaker certainly must have blasted the crap out of it. For an amp, maybe a Cambridge Audio 651 at about $700. It has tone controls, which you probably should have for a system like that. The only thing is, you probably want to play music pretty loud, which means you should look into a higher powered amp. It will mean you're going over budget, but there's no sense buying something you won't be happy with. Best of luck and hold onto your wallet.

All of these products come with in-home trials of 30 days. I doubt you'll be returning *any* of them. And those Tektons will play LOUD with that 150 watts/ch. Emo amp

I second Elevick's recommendation for Heresy's. You can match them with just about any amp-from a old classic NAD to a modern tube amp. They are very efficient, have great bass response and play loud. Rock on.

The Heresys have great bass dynamics but roll off early. Used Fortes (I or II) would be better, but more expensive.

OHM Walsh speakers and a 120 watt/ch or greater Class D amp is the ticket. Case closed. Exact model and cost will depend on room size and bass needs. 80w/ch or greater NAD amp would be another good option.
