giant passive radiator.

Explain?

[Jebus]

Edit; Ignore me, still ill.

[J0e Musashi]

Explain?

Yes please do.

My 2 front satellites are behind the front edge of my panel by about 6". They're wall mounted so there isn't much I can do about it. Is it some real bad problem or something?

passive radiators

a large panel in front of the speakers acts like a passive radiator, to explain; the large panel of the screen acts like an unpowered driver in a speaker cabinet. by taking energy (sound wave, not electricity) from other drivers it will alter the frequencies which will be audible from the powered drivers mounted in that cabinet. In controlled cabinet construction builders can use them to enchance fequency range and control (for an example check out Linn Komponet 110's).
In the case of large TV's, in front of the speakers, the panel which is acting as a passive rad. is uncontrolled and is sapping energy from the sound produced by the speakers, and giving nothing back. Which results in a reduction in sound quality.
Fixing; try if possible to get panels behind the speaker faces, a couple of inches or so should do in most setups, though it does depend on on the projection arc from your speakers. If your speaker are wall mounts the best thing to do is try and get the tv as close to the wall as possible, even if the tv cant be removed entirely from the speakers projection area, at least it's effect can be minimised. if, just for kicks, you want to play about with this, try listening to some music through the system. Move the tv closer to your listening position, keeping the speakers still, and listen again. you should notice quite a difference.

hope that helps. and if there are more questions i'll do my best to help.

Now you say it like that it seems like common sense!

[Skull Commander]

Some lovely minimal set ups on here. My love of hoarding prevents such compactness!

Can you say it again in English this time please? This isn't AVForums...

Simplifying it horribly...

Look at the face of one of your speakers without the fabric cover on if it has one. You'll see a set of speaker cones, if your speaker has a passive radiator then those cones aren't actually wired up to the incoming signal.

The active (powered) speaker will make the air inside the housing move the passive radiator which creates a slightly different sound to the original sound. It will distort what you are hearing but passive radiators can be tuned to control the distortion that is produced such as was suggested, moving the TV without moving the speakers.

That's not the most precise way of tuning them so you're never going to hear exactly what you should be hearing.

That explanation simplifies things horribly to be honest but I'm just trying to illustrate it.









...also, I'd recommend moving your walls out about a meter and lining them with bookshelves full of randomly placed books to diffuse the acoustics but I'm guessing that's probably a little more than you're wanting to do Brad.

My speakers only have one cone. They're the tiny Sony golf ball ones. Does this mean I'm exempt?

: that would be an ideal, but unfortunatly there are no exemptions. the hope would be that your smaller single driver has a narrow field of projection and the effect is minimised. ive done a quick doodle for you maybe that will help.

[J0e Musashi]

That's great thanks, I can totally understand it now.

I think I may be ok as my front speakers are quiet wide of the panel. I'm gathering the field of projection misses the panel entirely.

[concretesnail]

if it does trhen the effect of the panel will be minimised and you should be ok. in any av room/ setup it is always about finding the best compromise between layout, performance and living.

Some useful info there concretesnail, nice drawings too

Thanks.

[concretesnail]

cheers, glad to help.

No FSAA though I see
Cheers.
