room size question.

@bshaw  

according to your measurement your room is only 9 feet wide , not 12x12 .

What are your room measurements ?  

@bshaw 

OK  , measuring your speakers ( great looking ) from the center to the side wall at 36" , that would leave you with 62" center to center .  Are you measuring from the front wall to the rear of the speaker ? or to the speaker ? 

Have you tried the acoustical panels on the side walls and the diffusers on the back wall ?

I would suggest measuring from the center of the front of the speaker for side wall and listening distance , to the back of the speaker is ok for the front wall .

Try moving the speakers so that you have 36" from the side wall to the center of the speaker and see if you like the sound ,  you really don't have much room for moving away from the front wall , have you tried moving the speakers closer to the front wall with 30" being the closest before the bass becomes boomy and don't worry about having an equilateral triangle .

When a question is asked you receive a lot of good information to try  ,

I'll give you something exact to try or not , I've already suggested having the speaker 36" from the side wall leaving your speakers at 62" from center to center, the next suggestion is based on the listening angle that is equal to the angle of the speakers being 8' apart and the listening distance being 10' or 48-49 degrees , so if you can move your speakers and even your listening chair so you have 75" from speakers to ears ,  now measure from the center of your listening position 23" and aim the speakers to that point .  Toe-in even just 1/2" will make a big difference , I know you said you didn't like it but I have moved my speakers several hundred times ( it's free ! ) and for me this formula is the best , but it will all depend on how things sound when you move the speakers closer to the front wall .

Good Luck

pm or call me if you want to discuss ,

I see that you moved the speakers from 36" to 30" from the front wall , Did you hear any improvement ?  

Questions , are you leveling your speakers , have you tried tube rolling and what CDs or songs do you use for evaluating ?
