Hey T-bone,
I'm not Dan, but since he hasn't replied yet I'll tell you what he'd likely recomend. For rears I think you will be fine going with kit81's on the rears and sides. I did and have been more than happy with them for surround duties. As for the sub, that depends on how big your room is, how much you want to spend, and how loud you want it to play. Assuming a normal size room, if you want good output you could look to a shiva based sub, if you want great output you could look to a tempest, and if you want insane output you could look to a tumult. If this is for HT only you will probably want to go ported rather than sealed. There are a couple good designs posted on the Adire website if you go looking. Good luck!
George
