Multi Ch. speaker placement tips needed



Hello all,

I’m initially setting up a 5.1 system in a < 14ft x < 21ft < 8.4 room. Closed off 100%, save for AC ducts. The ceiling gently slopes up to 8.4 then back down, to about 7.9 ft.

All the speakers are Silverline Audio… Sonata IIs; Center stage; SR 15; Velodyne DD 15. If I add to this config it will be a pair of Minuets for the middle surrounds and another sub for the rears… that has yet to be decided though.

Center surrounds will need to be set onto the side walls if done at all.

Center and mains are set to the < 14ft wall.
Where is the center to sit? On the same plane as the Mains? Or behind them? How high off the floor?

The rears are on Sound Anchor stands and the tweeters are right at ear height, 48 – 80 in.

If I go ahead and add the senter surrounds should they also be set as the rears in height?

Higher? Making for a hemispherical config?

Lower? Making for an increasing slope up to the rears?

Thanks much for your experiences & interest.

The setup is set… short wall. The screen is hung, the PJ is set too. The room is finally shut off effectively during listening/viewing .sessions. The lighting is hung and done. The sound scheme is currently 5.1, though 7.1 might be the end result if I can figure out just where to place the side spkrs.

Now I’m considering dipole/bipoles for the surrounds and directional for the rears. There will be scant little latitude for movement of the rears or center surrounds. Greater flexibility is had with the center ch, mains, and sub.

The listening position is likely to be determined by the 2 ch performance + the visual image viability, and in that order. I’m figuring to do one pair of speakers at a time, mains … rears… then perhaps sides at some later date… then the center and lastly the sub.

Acoustic treatments will follow all the above…. Consisting of corner bass traps, first reflections and possibly some diffusers.

Where it’ll all wind up and how much acoustical treatments are used is anyone’s guess right now.

the biggest variable for me right now is deciding on the use of either dipoles or bipoles as either middle surrounds or rear surrounds.
Hello Blindjim,

I am using a pair of Snell SR.5 bipolar surrounds in my 5.1 system and they seem to integrate very well with my front speakers from a different manufacturer. They mount on the wall (side or rear) and provide very good rear/side fill for surround effects. They provide a wide "dog-bone" dispersion pattern that works well for surround effects. If you are considering bipolar surrounds for your theater you may want to check them out as they are very well made. -jz

Thanks

Snell! That was the name! I had forgotten all about them. But these are pretty pricey, aren't they?
