Because the front baffles of the speakers should not be behind the plane of any walls, equipment racks or other obstructions. The picture looks like the speaker to the right is at least 6 inches behind the wall and it is also corner loaded which is not good.
That makes sense. The baffle is about 1” behind that wall and there’s a few inch gap in between. I can pull it out to make it where the baffle is in front of that wall by 2”. -

Whatever you do on the right must be done to the left. If you are 12 inches off the back wall on the right, that is how much you need on the left.tjcinnamon wrote: »nooshinjohn wrote: »tjcinnamon wrote: »

Traditional stereo speakers could work better in that space but it can be optimized as much as possible for the L800s. They won't sound as good as they could though. The Atmos modules are not an issue however. All they do is add height by bouncing sound effects from the ceiling, not width.

The glass block wall is far too short. SDA needs a minimum 15 foot wall.Political Correctness'.........defined

That's what I did. I did some testing pulling it out and straightforward vs angling just a touch. Slightly angling sounded better from an SDA perspective (although it's less angled than before). That fake side wall (of insulation) made a world of difference. I'm going to continue to experiment though.
About 6 months ago I met with Accoustician Mathew Poes, he suggested based on my room, to angel it. His review on the L800's was stellar and convinced me to purchase them.
If I can run them straightforward as intended, that's my goal. -

I didn’t have a choice on the wall because me existing speakers and TV were already set up, my atmos and surrounds are in wall, and the sectional is larger than that wall.I'm sorry (not really), but you got bad advice. He should have told you to put them on the opposite wall with no toe in.
The toe in was a last resort. It makes sense if the speakers are 8’ apart and listening position is 8’ back.
Polk also suggests having a far side wall and yet people are saying closer to the side walls is better in some threads on here.
I dont think it was bad advice all things considered. -
They work pretty good, especially with my new fiberglass side wallTraditional stereo speakers could work better in that space but it can be optimized as much as possible for the L800s. They won't sound as good as they could though. The Atmos modules are not an issue however. All they do is add height by bouncing sound effects from the ceiling, not width.
For my next theater, I can design it with these in mind up front

No one said you needed near or far side walls. I just said you need side walls.
If your side walls are 15 ft (+) away... you basically dont have side walls as your first reflection points would be like the back corners of the room and you have a whole host of other things to combat.
At Troys, his were like 9 to 12 ft on the right and 20 plus feet on the left.
If your side wall is 6 to 8 ft away, that is a far side wall and should work fine.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

Yeah, they are between 6 and 8. I’ll recalibrate without the toe in and see how it makes a difference but I think I squeezed all I could out of this room.
Overall I’m very very happy with the improvement. That side wall moved it from Good to Great.

Seriously... drop the toe in.

No doubt, you've got a tough room. Just a thought, maybe install some sort of expandable pull out fake wall to entirely close up that opening leading back to your office area. SDA likes symmetry.Political Correctness'.........defined

Sidewall treatments worked wonders for me. But they are 1.2tls with walls about 3' away.

SDA thrive on symmetry. I have yet to hear them work as the should in any setting that did not allow for that. I believe the original SDA are more forgiving of room shortcomings, but the L800 are a completely different speaker.
In the OP’s setup, the L600 would have been the better choice, IMHO...The Gear...

Great idea! I plan on more or less doing that with that cardboard insulation wall which I'm going to have change out with freestanding GIK room treatments. The options are 2" and 4", based on their graphs I can't tell if the 4" do less absorption up top vs the 2".

Honestly, I think you'd be better off starting with a solid fake wall. You've already got more than enough acoustic damping on the wall above the sofa. You've got to let the music fill the room. Too much damping will suck the life out of it.Political Correctness'.........defined

What do you guys think of something like a partition for cubicles in offices? They could be easily moved.

I know what you mean. The good news is that I’m at about 80% of SDA compared to what I heard in the store. Before I put this fake wall of cardboard/insulation I had the effect too.
I’m definitely going to put a block up because it enhances the effect. I certainly have concern about being over dampened. -

Here, I was told you invented SDA??
(Joke),
But you are correct, they need to be "just right" or else it throws off the image and the whole thing "collapses". A tough room for sure, going by the pictures. -
Everything has to be equal and symmetrical with SDA. At both the speaker and listening end.
Probably the one really bad thing, is placing them in a room that is not optimum. -
Those office cubicles are very sound absorbing.
