I just ordered the Epic Grand Master InWall Home Theatre system and waiting for delivery.
I have a 65" LED TV which is wall mounted.

I wanted to know from the experts and other users about the distance I should keep from the TV to wall mount the left, center and right speakers.

The room is about 19' deep.

Thanks

The center, I would mount as close to the TV as possible, yet aesthetically pleasing. For the other 2, it would depend on the width of your seating area, the wider the seating area, the wider I would place the speakers. Also, if possible, I would enlist the help of 2 people and have them hold the speakers at different listening distances and heights to try out what you think sounds the best.

I recall some conventional wisdom about creating an equilateral triangle with the front two (LR) channels and the main seating area. That is, if the main seating area is 10 feet from the screen, the the two speakers would be around 10 feet apart. (I realize this doesn't make a perfect equilateral triangle - it would actually be slightly wider apart).

Wider is typically better, but taken to an extreme, the front soundstage can begin to break up. In my listening area, I sit 12 feet from the screen. My fronts are located about 11 feet apart from each other. I find the soundstage to be wide, but full, with nice separation.

In truth, it will depend as much on the amount of space you have and the aesthetics of your set up. You wouldn't want to flank a 42 inch tv with speakers spread 12 feet apart. If the equilateral triangle approach doesn't work, try to put about a foot of space in between the speakers and the edges of the TV for an aesthetically pleasing look and a width of soundstage to match your screen.

Yeah, every room is different. A lot depends on your seating distance etc. Generally, you want you tweeters at ear level when seated, but that is not always possible. Capn has good advice for the left/right speakers as an equilateral triangle or close to that would be nice, but it might look silly if you spread them out to far on certain rooms.

Hi Pritam,

Good advice from the Cap'n and Sir Quack, however, I tend to prefer a bit less than the equilateral triangle suggestions, mainly to avoid a "hole-in-the-middle" effect if you happen to be listening just in stereo with no center running.

That said, you certainly want a minimum separation of 6 feet or more to get some stereo separation and spaciousness. As others have noted, it's worth experimenting a bit based on your distance from the front speakers to the seating area with your particular room.

Regards,
Alan

The hole in the middle effect can be overcome with some speaker toe-in, at least that has been my experience.

The equilateral triangle is a rule of thumb and the width of the speakers should be adjusted for the best sound in that room. I would try running the speakers on stands of some sort before you wall mount them to give yourself the best idea of how wide you want to place them. Are you using the FMB to mount them with? If so, you can achiee a little toe-in with those mounts.

I have my L/R speaker separated about 10-12', but the left one is only about 6" away from the sofa, and slightly behind it. When I say behind the sofa, I don't mean that the speaker is being blocked, it's just kitty corner to the edge of the sofa, and closer to the back wall.

I've wondered for a long time if it's too close to the sofa. Could the sound reflect off of it because it's too close, thus giving me undesirable results?

Hi Cam,

There are likely reflections from that sofa but not enough to degrade the imaging. The material looks like leather, which would reflect more than cloth upholstery, but the main contributors in terms of room reflections will still be the walls and surfaces adjacent to the speaker(s).

It's generally desirable to have some first reflections to increase the sense of openness and spaciousness of the front left/right soundstage unless you're trying to engineer an acoustically dead studio control-room environment, which isn't a pleasant listening experience.

The goal is a mix of reflective and absorbent surfaces in the room, and most home living spaces achieve that through normal furnishings. Extreme taste in decor or design can certainly work against pleasing sound reproduction.

Cheers,
Alan

Thank you very much for that detailed and informative answer, as usual, Alan.

If it was an issue, I could move the sofa, but it's much more desirable in its current location.

Pritam, welcome. You should separate the left and right speakers, if possible, by at least the same amount as your distance from them. For example, if you're sitting about 10' from the speakers, they should also be separated by 10' or a bit more. With speakers such as your Axioms which have very wide dispersion there's no need to worry about a wide separation causing a "hole in the middle", especially if you toe the speakers in slightly so that the tweeters point at your ears.
