Best used floorstander on the FS forum under $2500

These need to be dynamic style floor standing. Not overly large. My amp is a VERY high current, pure Class A amp which does 50w/ch at 8 ohms and 100w/ch at 4 ohms, and will play 2 ohm stereo at 200 w/ch. .... So efficiency is somewhat important, but not too much so, due to the high current.

Room size is 14x20 ... so medium sized. I need a speaker that will rock ... No necessarily in ultimate volume, but in the ability to make drums and bass sound real ( no polite sounding Proac bass for me ) ... I also need these speakers to be able to play with enough resolution and control to unravel music like Tool etc ...

You can buy these used:

What brand and model is it? It would help a lot to know the character and quality of the amp.

I'm a big Tool fan, too. Both the Von Schweikert and ATC speakers I recommended above will satisfy all your needs. The VS will go deeper with more grunt, but both are very high resolution speakers. ATC's drivers are world famous for their extremely low distortion.

But, be aware that both speakers can reveal weaknesses in your system, especially amp quality, if they are not high quality.

The best picks for your requirements are currently the Von Schweikert VR4 jr, PSB T60, and Revel Performa F50.
