Noob here. Just assembled my first setup, but I have a few questions.
Here's my gear:
Receiver- Pioneer VSX-1021
Speakers- (3) SuperZero 2.0
Subwoofer- Lava LSP10
Everything running through my receiver via hdmi 1.4
14 AWG to my speakers
Belkin RCA cord for sub (LFE)
This setup is for a small area now and if I decide to stick with the hobby (already getting hooked) it will probably become a bedroom/secondary system.
My speakers have a frequency response of 85-20000Hz, should I have my subwoofer crossover frequency at 100 or 150Hz? I have done my research and many agree that 85 may be a little bit of a stretch (but such incredible mids/highs), but under these circumstances is there really going to be that much a difference between 100 and 150Hz?
With the 3.1 I have my 2 fronts and 1 center. Does it matter if the center is upright or horizontal? It is identical to my fronts, but can be placed on its side.
I have heard that having an identical front speaker as a center is ideal compared to using a dedicated center speaker; how much truth is there to that?
Optical versus HDMI; I may be hallucinating but I swear that picture quality is slightly degraded when it passes through my receiver (video converter off). If I were to go direct HDMI from my cable box to my TV and then run an optical out from my TV to my receiver, how much, if any, would this affect sound quality? I do love my HBO series'...
Thanks for all your help!
