I'd suggest you consider B&W CCM80
http://www.bwspeakers.com/index.cfm/fuseaction/products.models/Label/Model%20CCM80
and
Boston Acoustics VRI585
http://www.bostonacoustics.com/ds_product.asp?ProductID=195&CategoryID=30
I have both in different rooms and am quite happy with them for the price. I use the B&W in theater setting for both surrounds and for backs. I have B&W 804 and HTM2 up front.
