Just bought a new house,

H/T room is in the basement
Dim: 7'8" cielings, 17' wide, 19' deep

equipement:
Tosh 61" H/D rptv
Denon avr-4802
M-80Ti's front mains
Vp-150 center (top of 61" tv)
front right corner klipsch ksw-15 sub
QS-8's side surrounds with stands
QS-8's rear center surrounds with stands
M-80ti's rear corners for 7 channel stereo "B" (music listening)

now here are my questions....
is this setup too much for the room i have
what is the best placement for mains (spacing directly each side of rptv?)
what is the best placement of all my surrounds with stands (how far from listening area for side and rear surrounds)
should i bi-wire all my speakers for better sound?

thanks Ian for your reply in advance....

Hi JohnnyBeGood,

I'm not Ian but we tend to agree on most subjects.

On one hand, I'd say your system is only "too much" if you think it is. If it sounds great, then it ain't too much.

No, don't biwire. There is no scientific or acoustical evidence to support it, and I've never heard any difference whatsoever. If you want to try it, go ahead, but you can achieve the same end by simply using, say, 12-gauge cables, which will keep resistance very low.

I tend to think you may get too much bass emphasis with M80ti's in the rear corners, but every room is different. It's just that corners tend to give emphasize bass the most, and it can be somewhat uneven. If that's the case, move them away from the corners a few feet.

You might separate your M80ti mains by a greater distance but I don't know how far away you sit from them. I'd say 7 to 12 feet apart is ideal for the M80ti's, and the imaging is best when you're well back from them, perhaps 12 feet or more.

There aren't hard rules for the the side surrounds and rear surround placement--whatever yields the best sense of envelopment. But usually, multipole surrounds are more effective when they're further away (to the sides) from the listening area rather than closer. I like them several feet above listerners' heads, but since they're on stands, that's not an option. Experiment with them further away or a bit closer to the listening area.

Rear surrounds should be well back from your listening area, if possible. They should never cue your ears as a source of sound. Envelopment is all.....

Regards,
