As stated in the title. Thinking of getting a TV for my "mancave" and was wondering if actually it will effect the sound of speakers in a bad way? Most high end system i see in pictures dont have a TV behind. Instead its usually carpet or diffusers.

Since my mancave and system is in "process", I dont want to purchase a tv if it would have a large effect on sound quality. Thanks all  rockin out rockin out

I have my TV between the speakers and it does not seem to be a problem, I have not tried it without the TV doubt it will make any difference as long as its flat, wall mounted maybe better.

RE: Does having a LCD/LED television

Most kit is magnetically shielded now anyway so shouldn't make any difference to the TV or the speakers.

like BigH and many others here I suspect, the trade off of living with hifi is one of compromise and quite often you will find TVs with speakers either side, myself included. That said, I prefer my speakers besides the tele for movies anyway.

RE: Does having a LCD/LED television

Just tried it, if I move the TV forward it did sound worse, took it off the stand and it was better but sounded a bit dull, put it back and near the wall and it sounded slightly better for some reason, so I would not worthy about it, can you move the speakers around a bit, mine are 18 inch each side from the TV. Big plus if you watch movies or music dvds is you can use the hifi for the sound.

The short answer is No.

Ther longer answer is yes.

Any large item with flat reflective surfaces will affect the sound, whether it matters or not is up to you.

Interesting system by the way.

Acoustics and reflection points by the sounds of things!

In an ideal world you'd have nothing between your speakers and plenty of space to the rear and sides - something near the speakers will cause the sound to bounce off it and arrive at your ears slightly after the sound from the speakers.

There appears to be little agreement on this post so far, and certainly no definitive science.

My suggestion is you try it and see. If that is where the television has to live then that is where it has to live.

An object placed between the speakers is going to have little or no effect on the sound you hear.

Most of the sound exiting those speakers (in some speakers all of it) is going forwards into the room. It is not going to be reflected off anything placed between the speakers.

RE: .

I have a computer desk and monitor between my speakers. When I move them out of the way it does seem to make a small difference but its barely noticable.

RE: Does having a LCD/LED televisio

Very interesting I'm sure. This implies speakers in use are rear-ported type.

For what its worth I have a rack system atopped by a 37" TV in my set-up. Removing the TV makes a blind bit of difference from usual listening position.

In my experience there's no problem.  Might have been an issue back in the days of cathode ray tube TVs when the magnets / coils in the speakers could affect the TV picture tracking and the high voltage CRT could (theoretically) have affected the speakers or if you're playing your stereo at volumes high enough to knock the TV off its stand / wall mounts, but other than that I'd say no.

So long as the screen is behind the front panels of the speaker cabinets and there's at least one or two cabonet widtths between the speaker cabinet and TV screen edges I don't think theyre will be a problem.

Interestingly though, in a small flat I had for a while I had more problems with the el-cheapo microwave knocking out the satellite TV reception every time I warmed up a can of soup than anything else.

Quote:
Sound radiates from a driver in different ways. Higher frequencies act like a ray and move in straight lines from a point. As you get lower in the spectrum, they begin to radiate more like a sphere. By the time you get below 500 Hz or so, you’re getting pretty spherical radiation. By the time you get to 125, it’s purely spherical.

That said, imagine sound coming from a driver at say 100 Hz that is coming directly at you. There are other waves that are wrapping around the cabinet and bouncing off the front wall and then back at you. When 2 waves of the same frequency meet in this way (one direct, one having bounced off the front wall) there is an interface of the 2 waves (some describe this as interference).

I believe the OP's original post quotes 'a large effect on sound quality'.

The short answer is still, therefore, No
