Wellllllllllllll,

I am having to move into an apartment. I have only one area to place my system. This area although not too bad in room dimensions has  corner walls that I have never encountered. The corner are a result of having the area closed in creating a porch rather than having a deck. The "porch" has regular drywalls and a tile floor. Right now I have my speakers place just at the ends of the two walls, creating a distance over 6' to the front wall located in the porch. My electronics is also in the porch. What I am wondering is there a better placement? I have good bit of room treatments to place for instance I have tri-traps in these corners now. The biggest problem with the current placement of speakers is they are too close  and I don't seem to have the soundstage I am accustom to.

Any Ideas????

Might seem too simple, but sit closer, which changes the vectors that cause perception of width to the soundstage.

what do you think about this:

Looks like that would be even worse for increasing the soundstage.

I would think treating the two partial walls with what you have there would be most effective, or adding diffusion there.  For early reflections from the front wall disturbing the soundstage, I believe they act as if a solid wall 6' long.  Of course the first reflection point would need attention, I'm assuming you've already addressed that.  Additionally any distance you can pull the speakers out from the two partial walls will help, understanding it looks like you have limited space to do much there.

Is the 'bar' around four feet high? Could you treat the front of that bar with absorbers perhaps? My guess is that might balance things up and give you that bigger soundstage. It's only a guess though!

Could you move your chair further back and therefore pull the speakers out too, as well as putting them nearer the side walls?

How much toe in have you played with?
Crossing the axis in front of you & moving the speakers
back & out may accomplish some of what you are looking for.
You most likely will gain some depth, improve imaging and the width
aspect is the lone variable.

Thanks guys, I appreciate your comments,

John exactly right, worse,  I am just curious whats happing with those two parcel walls.

Letitroll98, That's the first place I have addressed. I may too much there right now, Tri-traps from floor to ceiling, a monster trap across in front of the tri's., bass trap on both main adjacent walls,  two broadband down the main walls at first & second  reflection points.

Hipper, I tried placing a basstrap covering the Bar, I did not really hear any change. But moving the listening point back is where I am now. I have moved the speakers appart  10' 11".

Carl V I have them toed ( 22.5 deg), This is the best sound thus far.

I plan on experimenting with toe-in all the way and pulling the speakers down the equallateral line towards me.

So far the SPL vs freq plots look OK and waterfall looks OK. But I still have to get subwoofer integration
better.



How High should broadband adsorption panel (24x48) be place on the wall ??????

If the panels on the sidewalls are at the reflection points, well, they should be centered on the reflection point! So height wise, the center of the panel should be at the center of the distance between your ear height and the center of the speaker height.
If they're for general reverb reduction (not at first reflection points) then higher up on the walls tends to get a little more effectiveness out of them (since the upper portion of the room has less objects to scatter the sound)
