Splitting Rear Surrounds

by supportlife / February 9, 2009 2:24 AM PST

My Rear surround speakers are spaced about 12'-15' apart , hung on ceilings.
I recently bought some splitting adapters and split both left and right rear surround into one additional channel to be used as a rear Center surround-similar to what a front center does. I essentially created a mono channel that contains both left and right signals.
Does anyone have any experience doing this, and have you noticed a more fuller sound as surround effects "swoop" from left to right,due to the center being consistently on??

no, and it's not recommended

but if you like it, who cares, right?

firstly, are you sure they are rear surrounds, and not side surrounds? Are you truly talking about 6th and 7th channels here?

There ARE bipolar speakers that can handle TWO channels. One channel per side (2 sets of drivers). They ain't cheap, but wanted you to be aware.

110-135 degrees for side surround mounting when using 5.1.

If 7.1, since rear area is covered, you are given more freedom in having sides at 90 degrees, and that is what I recommend.

Thanks for the post, the bipolar speaker sounds like a better idea...so I would need two sets of wire for Left/right and each w a pos/neg, right?
I think i will try that.
already try my orginal idea and it works but seem to notice less of the left and rear surrounds, even though sound is more uniform...also depends on video source, thank you again.

In reply to: Re: Center Surround

I was referring to splitting the left and right rear surround into one channel, so channels 4 and 5 would be mixed into a 6th...not really a real 6.1-just simulating in order to get better coverage. I cannot expand my system to more than 5.1

This sounds sketchy...

I would not recommend doing this; I think you may be bi-amping that speaker! If you have one set of binding posts on a speaker connected to two outputs from your receiver, in ANY way, I would highly suggest disconnecting it. Like now.

Pros developed 7.1. You are the amateur.

If you like the sound then just do it.

Just get 2 more speaks and place it on the rear (and space them that sound best to your liking). Good luck and enjoy.
