i was thinking of soffit mount like in the studios but since me room is not wide enough i thought (3m) i thought what would if i soffit mount in the corners.
is the wide dispersion a problem?
the speakers are diy 4 way active and they can be adjusted with dsp.
i have seen line arrays build like that but they are directional above a frequency.
do you believe it could work with normal wide dispersion drivers?

I really like corner soffit mounted, aimed at the room's opposite floor corners, but it depends on how far away the listening position is to put it in the 'sweet spot' as to how much they can be angled down, so can you sit 3-4 m away?

I like corner soffit as well. Ideally the speakers will be made to fit in that position, if you are adapting box speakers you may have to get creative.
@GM, I find you can be closer than that. My speakers will soundstage as I walk between them to the wall. I'd like to know why some say you need distance for them to blend, or take, but I think sound off the walls and good crossing goes a long way.

Yes, if one sets the angle to work and/or have a wide/flat power response; Virtually everybody I've known/read about though place[d] them at 45 deg to make them simple to build, so with rising on axis speakers one ideally needs them to cross in front of the 'sweet spot' with this 'gap' a personal preference.
So what speakers do you have that will soundstage well into the treble all the way to the wall?

As you suggest, angled at 45 degrees out of the corner crossing in front of the sweet spot. The listening axis also chosen to be the smoothest and best representation of the power response. Crossed considering both and designed for minimal wall interaction at higher frequencies, wall cooperation lower down.
It is easier to make a wall soffit from a box speaker because of the usually flat baffle. Corner is more suited to quartered radial (for midrange and down at least, high range options are probably more open).
Anyone got a picture?
I once envisioned a speaker system that was triangular/pyramidal speakers made to fit in the upper corners of a shoebox room. Seemed like there might be issues with image height and early reflections. Perhaps some nearby absorption would make the latter better, since anything small enough to fit would probably have pretty wide dispersion and spray the walls, but I thought CD horns might be an interesting choice....and I suppose most speaker geeks have thought of 1pi corner line sources...

thank you guys for your answers.i thought nobody answered hence the delay.
from your answers it seems a good idea.
since i already have the speakers and they are wide dispersion do you think early reflections would be a problem?
yes i can sit at any distance.

The effect of early reflections can be stronger when you move in to the corner. They can have a higher SPL and be closer to the direct sound in time. You could use absorption to reduce this, a better solution would be to build the speaker to match the corner.
That said, the treble might be best not accessing the walls, but this is easy to achieve at these higher frequencies. The midrange and lower midrange could use the walls if you are creative. Many considerations with the bass, it could be better or not depending how you do it but corners open up opportunities.

Some manufacturers design speakers for corners, Tannoy spring to mind. The corner will act like a horn so the speaker has to be designed accordingly
So have thought of putting pyramid shaped speakers in the corners of my room for a while but I just don't have the tools to make speakers anymore. I'd love to see what you are planing here.
If you google 'corner soffit mount speaker' you will find a lot of studio pictures. 'Soffit mount' is a common studio term - usually a 'corner soffit mount' is really a wall across the corner angled toward the listening position with a relatively ordinary speaker flush mounted in it. I think that is what the OP means.
I think you will have timbre-altering early reflections unless horns and/or absorption are used. In a recording studio there are reflections off the desk as well.
My idea for the pyramids was something like a partial soffit where the speaker is a triangle in the upper corner with the height perhaps 3-4 times the width.

i am planning to remove the drivers form the cabinet and use as cabinet the corners adding wooden baffles.
up to what frequency should i expect a boost?300hz or more?

There is no boost as such, as frequency decreases a speaker becomes more omnidirectional so less energy is radiated towards you, often this is compensated for and is called the baffle step correction.
this is not correct.reaching the wall behind the speaker there is a boost of 6db which is equal to the baffle step loss as you discribed it but reaching the side wall we have an additional 6 db total 12db and if we add the floor there is 6 more total of 18db.
i am not sure until which frequency it takes effect.

It's still not "boost", it just means the lower frequencies aren't being lost towards the rear. BSC is a fudge (I used it as an example to show where the notion of a "boost" came from) the loss is on a continuum related to the frequency.
yes but the result is the same.any way the answer to my question must be something like the closer the drivers in the corner the higher the frequency it takes effect?any idea how to calculate?
Correct, it would relate to the distance, also to the drivers directionality, which would be different for each of them and the cabinet design. This is why I believe it would be best to place a properly designed horn in a corner position otherwise there could be a number of issues regards reflections and comb filtering with the boundaries so close and at such acute angles
