Dealing w reflective surface between loud speakers



Hi all,

I know its not ideal to have a big plasma or LCD tv screen slap bang in the middle of your two front loudspeakers and yet i'm sure that i'm not alone in having precisely that!

In your experience how has/does a reflective surface between the speakers impact the perceived audio quality and what solutions have people found for this problem [other than moving the screen somewhere else]? Some form of absorbent cover for the screen might make sense but where would you source this?

Many thanks

A friend of mine has the same problem. He purchased a large rectangular piece of audio foam (the kind with alternating indented/extended triangular rows) and just hangs it in front of his TV with velcro whenever he's listening. I think it cost him like $100?
In my huge swimming pool room I have a set of Bose 901 speakers nestled unobtrusively amongst the potted plants. In between the widely spaced speakers is a very wide and high window unit, reflective as hell. But, the Bose speakers project their sound up against the wall, and its reflective nature is ideal for the Boses. I attribute the good imaging to the environment these speakers operate in.

Many thanks for your responses!

My plasma sits about 3 feet behind my speakers - but even at that distance it hinders the soundstage. My situation may be worse than others because i use large planar speakers with bi-directional ribbons. A quick check last night with throwing some towels over the screen showed enough improvement for me to take this project very seriously.

I will check out the foam and comforter options locally to see what can be done.

Cheers.
Here is the way the designer of Rethm Saadhana speakers solved the speaker (boxes) vs room interaction problem.
Very clever and inexpensive I might add.

if you can get those speakers out a couple of feet from the plane of the TV screen, which should be no problem at all if you have already pulled your speakers out into the room far enuf to enhance the sense of depth of image and avoid unwanted bass enhancement, I wouldn't do anything.

I second Newbee, I would add that if you can get at least two feet between the edge of your speaker and the TV then this will help a lot too (distance has a huge impact as sound spreads geometrically and therefore signal drops rapidly with distance). Placing the TV behind and more in the acoustic shadow of the speaker baffle edge will help too (although sound waves do go round corners too - at least the signal level will be further reduced.)

Placing the speaker with a few inches of the TV is a No no - the sharp TV edge and the small gap will interfere and may even collapse your soundstage so that you become aware that sound is coming from the speakers...

The perfect way to deal with the problem is to have a smooth flat surface or wall that holds your speakers and the flat TV screen - everything flush as can be - with smooth transitions and as little in the way of sharp edges as you can design - gaps should ideally be filled with acoustic foam/batting and a picture frame smooth transition between joints.
