Room help

The long wall is usually a good place for the speakers in a room such as yours. I have a similar situation but in reverse (if I’m reading your post correctly) whereas I can’t use the short wall due to asthetics and such and the fact that there is a wood covered Lally column separating the room. I find the system just so happens to sound better this way in my room. I might add that the room is fully finished in drywall, and fully carpeted, with a gigantic sectional couch and countless throws, pillows and blankets. There is no wall on the right side, open to rest of the room. It’s a pretty good mix of absorptive and reflective materials. Still working on a few diy treatments...the only thing I can recommend to you is maybe pull those speakers closer together by about a foot...and tow them in so that the axis of both speakers crosses just in front of you at your listening position. It may or may not improve Soundstage and central image. I use Tannoys and they are big proponents on serious toe in. A more radical toe in will decrease the effect of room boundaries to a degree.

Thank you!  Yes, my speakers are usually along the long wall.  Moving them to the short wall however really opened up the sound.  When I move them back in a few days I will play around with the toe in.  I should have mentioned I am using Monitor floorstanders.  They tend to produce good bass response so I think they may respond very well with a generous  toe in.  

Ok, maybe I have answered my own question,  Or at least am having a pleasant conversation with myself.  But I'd love it if someone helped me work through this...

Is it possible that the spacious sound I get when my system is set up along the long axis is because the back wall, which is brick,  is so far behind me (about 17 feet) and the reflected bass is not there to muddle things?  In this case when I go back to the short axis where the back wall is 4 feet behind me would the use of bass traps help me achieve the same effect?

I'm not sure we can replicate this exactly, but start with diffusor panels behind you and between the speakers.

My feeling is you can replicate better sound in your earlier orientation. Here is what I think… you can see my room under my ID. Consider putting up some photos.

First… if possible put the brick in front (to quiet the sound stage)… but also cover with a sound absorber (I use a heavy wool tightly knit carpet)… this will improve depth of image as well as widen.. You want to highly dampen the wall behind you. I suspect this is where you are really losing in terms of this location. Only an amp in between speakers. Heavy carpet between speakers and you.

That is the “big” stuff. Then you really want to fine tune… a diffusion tube behind each speaker and center behind amp. Tube traps in corner. Absorption bolsters along wall floor corner in front of listening wall. Finally corner diffusers at all wall - ceiling corners.
