I almost decided on building a pair of corner line arrays..
Room is 20x16,5 feet.
I haven’t heard other recommendations on listening distance other than close isn’t good with line array.
Speaker will be in corners on each end of the short wall and toed in 45 degrees.
Anybody got a recommendation for listening distance?
Best regards
Ben

Hey rayma, thx for quick answer,
So my best bet is to put up a big absorbing panel on the back wall To limit reflections and put my seating 2 feet away from wall.

My arrays / ears form a triangle where each distance is approx 2,8m apart.
The front baffle is about 105cm out from the front wall.
I sit 80cm out from rear wall and use a bit of absorption panels (150-250mm thick)

I have arrays and measure at ~2.7 meter. Listening is done at 2.7 to 3 meter from the arrays. Arrays themselves are about 3 meter apart.
Another note:
Every ridge or edge that is parallel to the line of drivers, worst are parallel planes, is going to have an effect too. Corner placement seems like a good idea, until you realise you can't have the drivers in the apex of that corner without creating additional edges parallel with the drivers. Absorption may help there where the baffle ends and the corner begins.
Smaller drivers sum better at higher frequencies, however they tend to have less low frequency potential. Be sure to consider all compromises arrays bring. You'll need a lot of EQ to get an acceptable response at the listening position. Lots of info in the several array threads on this forum.
I love the results I get, but make sure in advance it is the right compromise for you. It takes quite a bit of dedication, not only to build them but also to make them behave.

Thx for the answers guys, ive spendt a fair amount of time Reading in your building threads. The Energy you all put in to your projects is inspirering!
Im aware that corner placement has it’s ups and down.
My room is a nightmare sound wise, 90% of room surfaces is large glass panels! Yes im aware that cant possibly get any worse.
But to make it even worse I cant have speakers that are pulled out into the room. Very shallow speakers with Corner placement is my only option.
I have plenty of bas/sub drivers to make multi subs, but first i want to see if i Can even make the Mains Sound decent in that room.
I Can make absorbing first reflection/Ceiling/back Wall panels. I know a bit about small room acoustics, changes Will have to As subtile As possible and not ruin The look of The room.
Im planning on using minidsp hd with dirac.
I have not been able to come up with a better idea than a corner Line array. If you have any advice i would appriciate it.

Distributed mode loudspeakers can solve for your window problem. They can also solve for your space problem. And they are less expensive than line arrays.
Here's the thread on distributed mode loudspeakers. A Study of DML's as a Full Range Speaker
In your case, DMLs are an advantage because they generate a "diffuse" soundfield, which means the first reflections aren't strongly correlated with the direct source. Our brains aren't powerful enough to recognize lots of weakly correlated reflections with the direct source so we ignore them.
A microphone + computer is powerful enough to hear the reflections and it looks like the attached frequency response graph. Your brain buckles under that kind of pressure and taps out.
You said you intend to use DSP so that's why you can get away with DMLs. If you wanted to use non-digital technology DMLs wouldn't be as successful. Many people interested in full range speakers like to use traditional technologies so DMLs aren't a good fit for them.

So with lines in corners toed in 45 degrees, you optimum listening position isn't terribly critical. Futher is better from a combing point of view and that room is large enough for 4m or so. But the other consideration is the horizontal beam width. You don't want to be so far off the horizontal axis that you lose the high treble. That is the conundrum for corner line arrays. If you design them to fit tightly into the corner, then the fixed toe-in angle constrains your listening position but you need a minimum of absorption on the near corner walls, 4" thickness is good. Alternatively, go with twice as much absorption, pull the arrays a little bit out from the corner and give yourself the freedom to aim them optimally.
That curved baffle is a nice touch. I don't think it will completely eliminate reflections where the baffle meets the wall but it will likely change their angle of reflection so they may not come back to the listening position. You would have to ABEC it to know for sure.
Even so, when we you go to set it into the corner you might find baseboard in the way and not get as clean a juncture as you planned. But you could always pull it out of the corner and add absorbers.
I applaud the off center position of the driver on the baffle. That way a boundary null from the front wall doesn't reinforce the null from the side wall on axis.
