Surround recommendation with TSi400 and CS20

[lozman]

Hello Everyone,

I just ordered my first set of Polks; a pair of TSi400s and a CS20 for the center channel. I didn't order any surround speakers yet because I'm not sure which way I want to go. I have a Yamaha RX-V573 7.1 channel AVR to connect them too though I'll probably start off with a 5.1 setup first and think about 7.1 later. So my questions are;

1. Am I likely to notice any tangible difference if I bi-amp the fronts while I can with the two spare channels?

2. Which left/right surrounds would people recommend? I like the idea of in-wall speakers but I don't know much about them and I'm not sure which ones would be appropriately timbre matched with the TSi range if any. If not in-walls which others would be good choices?

Any advice/suggestions/recommendations welcomed gratefully.

Thanks,
Lozman.

Timbre matching the surrounds isn't t as important as the front three. Maybe the FXiA4's or A 6's . If you bi-amp the fronts you will be just cutting power to the rest of the speakers.
