I use their 8" square speaker @ $40 / pair. They sound OK for whole house audio, but for a surround, wouldn't you want something a bit better for you theatre room. The price on them is right, but I am not sure if they would be up to the quality you would want. It might be good to first pick out your front speakers 1st and then find something that would match them well, rather than purchasing the surrounds 1st. Just my 2cents.
