Thanks for the reply.
Regarding to in-ceiling speakers, my living room is open space design, since there is no border / wall / spiltter between itself and the kitchen adjacent to it, I have to put in-ceiling speakers for side and rear surrounding. However I will be able to use bookshelf or on-floor for front, but what to buy is undecided yet.
Regarding to the SW, I don't mind raising my budget a little bit, but the BIC F12 is really too large for me (overall 20" wide), I can spend a little bit more than $200, but prefer 8" or 10" size.
I will use this system for watching movie instead of listening to music, so bass experience is (kind of) important to me. But from the AVR I pick, you can see that I'm using veyr low-end equipments.
I don't mind raising my SW budget a little bit higher, say what can $200 buy me to provide better movie watching experience than the Polk Audio PSW10 ?
