Front speaker distance, from each other

**gadgtfreek** · 11-22-2011, 01:18 PM

Yepp, more audio questions. I'm slowly moving from the world of video learning to audio learning.

Doing some reading, it appears a constant that comes up for fronts, other than ear height blah blah blah, is the "triangle". Basically, you measure viewing distance, then make your two front speakers exactly that distance apart, hopefully with the center position as the equal point in between them.

here is a simple drawing

Friday, I plan on mounting my display to the wall, running new speaker cables and installing added surge protection. I figure this is the best time to do a little speaker tweaking. At this time, Id say have my speakers about right apart distance wise, but not sure. Then, once they are placed apart, you use a laser pointer and a object at the center position, to toe the fronts in.

Any other advice?

Dolby recommends something more like this, which would be figuring your angle and then moving the speaker out until it hits the center spot, may be better

My concern is, my ProMonitors are not high speakers, and if I have them out too far, there may be a gap (I kind of think the triangle idea puts them out too far apart). Another recommendation is just 3 feet off each side of the display, toed in, and 1-2 feet away from walls.

Another take, guess I was slightly wrong on my interpretation of the "triangle"

Front Speakers
• Sure, you will have a center-channel speaker, but don’t use this as an excuse to put the left and right speakers 15 feet apart. To provide the best combination of stereo spread, imaging precision, and coherence with the picture, a good rule of thumb is to position the left and right front speakers so that the distance between the two speakers is equal to or preferably a little less than the distance from each speaker to the listener. For instance, if your speakers are 7 feet apart, a distance of 8 to 9 feet from each speaker to the listener is excellent. You should avoid setting the speakers farther apart than the distance from each speaker to the listening position.

• I recommend that you place the speakers at least 7 feet apart for any listening position that will be 10 to 12 feet from the screen of a one-piece television and no more than 10 feet apart. For a front-projection setup, you should position them no more than a foot or so to the left and right sides of the screen.

• Many people sit too far from their TVs and speakers. For a 7-to-9-foot speaker spacing, I recommend that you sit at least 8 to 12 feet from the speakers. If you sit too close, the sound from each of the speakers’ drivers may not gel properly into a coherent whole. If you sit too far away, you’ll hear too much of the room. If you’re really unlucky, you’ll hear an amorphous blob of sound rather than a well-defined soundstage.

My current ear distance to each speaker, is actually a little less than they are apart from each, so Im obviously too wide. I sometimes think I can pick the right speaker (closest to me) out too easily, and this is probably why. The bold part above, kinda of represents how my setup should be.

My front speakers are 5ft from the center speaker which gives me 10ft apart. I'm following the guide line for Front- projection setup which is no more than a foot or so to the left and right sides of the screen and a total no more than 10 ft apart. My rears are 1.5 ft behind listening area toe in at a height of 7 ft angled down at 15-20 degrees.

Thanks. Im thinking, with my reading at my Distance, 8-10 feet is probably best.

I also spoke with Def Tech, and got the same recommendation. Fronts are 9 feet apart and toed in towards the center (used a laser). Center sounds better that it is now on top of the stand, instead of that small hole.

Must have done a decent job with my triangle setup. Only one inch difference between the front right and left, to the center position, after running audyssey.

I got my FL & FR toe in but pointing towards the left and right shoulder of main listening position. If you look at the picture you posted it shows pointing to the head I did it to the shoulders instead.

**gadgtfreek** · 11-24-2011, 09:13 PM

That's what I did. They both arent hitting on center, little off each way.

For me it opens up the sound stage and helps if you are not sitting in the main position.

I wouldn't angle the speakers DIRECTLY at the listening position. That creates a VERY small sweet spot.

Good speakers FILL A ROOM with sound, they shouldn't shoot sound at a target, so to "speak"

And they are designed according.

Many speaker comps recommend having the speakers literally straight (perpendicular?) from the wall. I've always found a slight toe-in the best. Keep a decent distance from the wall (assuming floor speakers) at least a foot, speaker sound includes the area behind.

And most people have their front speakers too far apart. I have a 65" TV and my speakers are now about 18 inches from the TV. I've found having speakers farther apart does nothing to improve the impact.

But it IS all suggestive, of course. Depends on quality, brands, design, room, you, etc.

I agree on too far apart, it sounds a little more blended and proper with them 9 feet apart. Due to aesthetics, 10" from the wall is the best I can do

Our "center spot" is a round glass end table between my chair, and my wifes. I have the right speaker (my side), aimed at the edge of the table closest to me. I have the same process on her side of the glass table. So it's not quite center, but close. We have a rectangular room, so I dont want them too toed in, because on chair is way out of the area.
