Hi newbie here using RX-V679. I need some advice on speakers setup.

1. How significant is a 5.1 vs 7.1 setup? Is it worth it especially considering that I would watch only 3 titles/year.

2. Is there a significant difference between using small surround speakers vs. larger ones?

3. Due to living room design, the most convenient location for my surround speakers is about 40/45 degrees behind listening position at 2.9m/2.5m distance. Is that ok or it would be much better to put it at 2/-2 degrees @ 2.2m/2.2m distance?

Thanks.

For the speaker size, I was actually referring the small/large size terms used in the AVR setup. Full range (or not full range) speakers, I think. Sorry for that. So the question is really whether full range speakers have a big impact when used for surround. Agree that the physical speaker/enclosure size don't matter when looking at performance rather than the design is more important.

Ya, looking for accurate setup can only be done by actually testing it. I was looking more for a rule-of-thumb/general setup advice based on the experience you guys have on what will or will not work and what matter and does not matters. Otherwise I would not know where to start and what to try. Just like how an experienced wire-man can tell roughly what wire size to use without calculating.
Hold on, you almost lost me with all the 3rd .number. Had to google those ceiling speakers, but I got your point.

Anyway I have my system setup in my living room, about 4.3m width x 5.9m x 3m high plaster ceiling. On my right-

I wonder if its possible to use JBL Charge 2+ as satellites. it seems this little boombox is not only clear and nice but also bluetooth.
