AT Screen, speaker baffle proximity

Is the idea to get the main LCR as close to the screen as possible ? My mains are above ear level to get them centered on the screens height, I found it distracting when they were lower. I aim them kinda down to the LP, which creates some distance to the Spandex material, I did white over black..........

How much of an angle "you kinda aim them down" will spell the difference. The suggested distance between the front edges of the speaker Cones / HF Drivers is....as short as possible. Under 2"-3". The HF Dives are the most crucial, and since most speaker designs have them toward the top of a speaker Cabinet, you'll want to place them so that the top edge of the speaker is virtually / almost flush with the inside surface of the spandex . But not touching, obviously.

It should not take all that severe an angle to get your sound going toward the direction your wanting, so at most the bottom edge of the speaker cabinet would be 2"-3" recessed.

I just glanced at them back there, oh wow, they are about 6" away, let me make some changes and see how it changes the sound

Now there is the issue of tow-in distance that creates

As long as thee is only 3"-4" distance at most from the furthest corner's edge away from the Spandex, it's bound to be better than any further distance would be.

Not really anything more you can do other than create a shallow recess in the Wall for the most inward corner.

I ended up pushing them flush with the screen, time will tell

I have found the hard way that if your LCR speakers have any bass to them they will make the screen shimmer/ vibrate if too close... obviously ymmv depending on tension of the screen material and amount of bass coming from the speakers... what is your LCR crossover set to? I found at 70hz mine affected the screen

Most of those who have used 2 or 3-way Cabinet Speakers or In-Walls have found that the amount of cone excursion, and the resulting air displacement is not enough to affect Spandex, because Spandex is far more permeable than conventional, more denser AT material. The air pressure passes through with less resistance. Conventional AT material suffers from resisting such displaced air, affecting sound transmission in the process.

Those who have very large, dedicated Bass Cabinets don't have to place them in such close proximity, because there is virtually no combing or attenuation of such low frequencies. However common sense would dictate that any long excursion Bass Driver that pushes out considerable air pressure would not / should not be placed to close to any denser, more restrictive material.

I never went back to move em forward, my bad. Now that i have them in a location closer to the screen, i'll prop em up, aiming them down alittle.

As long as they point at my head, there isnt a real issue to having them above ear level, is there ? I had my screen directly in front of my LP and quickly raised it up, ear level and eye level just wasnt comfortable. Bottom of the screen is at 32" now, 100" wide and 12' away.

Your all good. The direction of dispersion, combined with the location of the listening level, that is what dictates effective performance....and you seem to be able to head that direction.
