Dynaudio Contour SR as surrounds?

I had them. They sound good but you will need high power amp and a sub.

all speakers used in surrounds in my opinion should have a low range of 25hz to 30 hz because there is no standard when the audio is mixed and information can be lost. for example Diana Krall her piano comes out the rear speakers
and her voice out the fronts,so if you don't have good speakers in the rear it will sound like an echo

4425, You can't go wrong with those speakers. I have a full Dynaudio (Confidence/Contour) system. They can handle lots of power and almost never break with regard to sound quality. How large is ur room? and What's the rest of ur system consist of? Forgive me if u already know this, but Dyanaudio is never edgy or bright.But yet, very detailed and well balanced. I use Theta Casablanca III/Balanced Audio Technology Vk6200 Amp in my system. Good luck.
