Solution for surrounds too close and centre below image

I was mucking around in my theatre and came across an idea to solve the problem of side surrounds being too close to the side of the couch and the centre speaker being too low below the TV.

I put my side surrounds (sealed enclosure) behind the couch at ear height but pointing directly away from the couch and towards the wall (turned 180deg from their usual position in other words). The sound is then reflected back to the listeners but is now coming from twice the distance and due to the increasing cone of sound is less direct and virtually reduced the hotspotting to zero.

Then I thought it may work for the centre speaker too, so I pulled it out, turned it round 180deg and angled it up to point just below the centre of my screen and it actually worked

So this could be a solution for narrow rooms (where there is a solid wall to each side of the seating) and for people who can't do an AT screen but still want the sound to come out of the screen/TV and not from below.

If it works for you... that's great. Enjoy.

"Bouncing" the surrounds to create a more diffuse soundfield had been around for decades and I have used that trick myself in the past with great results!

However, reflections for the center channel are always discouraged and usually end up "smearing" the dialogue...but like Ratman says; whatever works for you!

Don't place a center below a screen. That's my suggestion.

I don't - I have an AT screen
I just thought people might like to pursue the bounce option when they are limited for placement and more for the less dedicated viewing/listening environmet.
I have never seen this method mentioned here before during many threads on speaker placement so I just threw it out there.


I am very happy with my bouncing side surrounds after living with them for a few days. In my room it is better than having them either directly to the sides at approx 3' away and better than at 80deg (slightly in front).

I'm a newbie, so I don't have any 'original' ideas or beliefs, so please take my comments with a grain of salt. But what about utilizing acoustical treatments on the walls, to minimize the reflections that are causing you to need a compromised workaround?

How about bouncing the surrounds at a 45 degree angle and pointing up to the ceiling and back wall? Would that work?

How about angling the center up towards ear level?

This solution is for side surrounds that are too close to your ears - nothing to do with reflections causing issues and it is not what I would call a compromised workaround. I have been listening to the reflecting side surrounds for a while now and IMO they actually sound way better than speakers firing directly at me form 3' away.

But the sound is still coming from below the screen. If you turn the speaker around 180deg and point it up slightly at the centre of the screen then the reflected sound you hear appears to come from the middle of the screen and not from below it.

And write "Bose" on the back of the speaker.

Now I hear ya


Not quite what I am describing though.

If I get enough motivation I will post up some pics or drawings of what I mean for those that I have not explained myself properly to

Oh, we get it. You turned your CC around, angled it up and bounced it off the rear wall behind your AT screen...doesn't take a rocket scientists to visualize it.

We are just saying that theoretically it should not work very well...but if it works for you, enjoy!

Yes and No

Yes - I turned the speaker around and bounced it off the front of the AT screen (which has a non-AT material behind it except where the centre speaker is of course).
No - it does not work for me as I do not run this - it was just a 2-second experiment to see if it worked. I am sticking with my centre behind my AT.

My side surrounds however are working very well bouncing off my side walls

Just curious...
What is the make/model/size of the AT screen that you purchased?

Ah... I was wondering who "manufactured" a screen with a cutout in the middle for a CC speaker.
