I have a new home theater room and I just bought some new 5.1 speakers.
My current amp is an Onkyo HTIB 6.1 amp (running 5.1 speakers), but I plan to upgrade to a 7.1 Denon AVR-1712. I was wondering what I should do when I expand to the new receiver? I rarely listen to music on it. It’s for bluray movies, which I watch via my PS3.
My current setup:
Energy CC-10 : Center
Energy CB-10 x 2: Front Left and Right
Energy CR-10 x 2: Surround Left and Right (Has Bipole/Dipole switch)
Polk PSW10 Sub (Carried this over from old setup. I already had it.)
Option A: Add 1 rear surround speaker for 6.1
Pros: Cheaper than adding 2 speakers. Maybe I won’t be able to tell the difference between 1 and 2 rear surrounds? I’m not sure.
Cons: May not be as good as 7.1
Option B: Add 2 rear surround speakers
Pros: Pretty standard at this point. Some movies support it.
Cons: Some movies still don’t support it.
Option C: Add 2 front height speakers
Pros: Many people believe these are better than rear surrounds.
Cons: Do they even make movies that support this?
Option D: Just stick with 5.1
9.1 is not an option because there are no 9.1 receivers in my price range of $400.
Concerns: How high do height speakers need to be above the front left and rights? My ceiling is only 6’8”.
The attached diagram shows my current speakers in red. The fronts are at ear level. The surrounds start at 6’ in the air, and fire sideways on both an upward and downward angle (since they are switchable between bipole or dipole).
The green boxes are where I would put rear surrounds if I had them. If I used heights instead, I would put them above the front left and right, about 6’ in the air (can’t go any higher due to the ceiling.)
