@likat , Your problem with the original orientation is that you are sitting way too close to the rear wall. You can try and add a lot of absorption to the rear wall but it will never sound as good as the new orientation. As a rule of thumb you want the listening position in the middle of the room with the speakers in a symmetrical situation. They should either both be next to corners or both along a wall away from corners. Both speakers near corners is better for bass but it puts an early reflection right next to the speaker which should be deadened. All this depends on the type of speaker you are using. I am assuming you are using a point source dynamic loudspeaker and not a panel speaker like a Magnepan. Symmetry is crucially important for stereo systems. Any variation between the two channels blurs the image. Achieving perfect symmetry is not easy. No two speakers of the same make and model are exactly the same. There will be slight variations in frequency response. Add the room and you can get wild variations in frequency response between the two channels. All this can be managed depending on how much money you want to throw at the problem. Getting any system close to perfection requires a measurement system and microphone ($300 at Parts Express) and digital signal processing (another $3000). Trying to do it by "ear" the old fashioned way is like duck hunting with a sling shot.
Room help
I'm new to this. I have of late been fascinated reading here about the room as one, if not the principal, component of a well tuned audio system. More recently I chanced upon a discussion about irregular rooms perhaps lending towards the best sound.
Well, I have an irregular room. It is approximately 15' x 27' with an 8' ceiling. It has a trapezoidal cross section (sitting on the top floor of my home under the eves), has a dormer and a staircase up from the lower level at one end. At one end the wall is brick and the other three are plaster. Carpeted.
I have my listening area set up on one end of the long axis (oriented transversely along the short axis of the room if that makes sense) . The speakers are 9' apart and 8' from me. Few feet from the front wall. Today I rotated everything 90 degrees so that now the speakers are facing out along the long axis of the room. The speakers are still 9' apart and 8' from me. But the back wall is now some 18' behind me instead of 4'.
The sound is much better. I've been listening for hours (with a pause for food, saying hello to visiting relatives, assuring my wife I'm still alive, and such). More "spacious" is the best word I can use to describe it. The soundstage is bigger.
However, this layout is much less pleasing from an aesthetic standpoint (please don't judge me harshly on this). Soooooo.... my question is: Is there a way to recapture this improvement in some way while maintaining the original orientation of the room (across the short axis of the room)?
Thanks for reading and I eagerly await any responses.
