Asymmetry Bad


Just upgraded my speakers to their next generation, which are slightly taller. With the previous pair I had noticed there seemed to be a modest downward angle left-to-right in the soundstage, instruments and voices perhaps a bit more pronounced and "clearer" on the right and the sense of ambience perhaps a bit more prevalent on the right, but it was very easy to assimilate into the listening experience and was seldom notable. Messing with the balance just made the left louder, but not really equivalent to the right.

With the new speakers, I quickly noticed a relative absence of ambience, echo, space, etc. on the left. The disparity was remarkable and distracting. While my room treatment is symmetric throughout, I had two racks of stereo gear in the front left corner that I thought might be causing the problem. I reluctantly moved the equipment off to the right and a bit behind the listening position (a multi-day task if you include ordering and replacing cables, tubing for the tonearm air pump, and more room treatment to fill now empty spaces), and voila! The sound of the hall is no longer just on the right and the soundstage is level.  PITA but worth it

Glad you figured it out. In my house of stereo the bulk of my equipment is on the left of the listening chair, offsetting this are many vinyl racks on the right side. As to the front, just the TV setup dead center between the speakers.TV covered by a wool rug. IMO the key is to keep everything in the entire room balanced, but most importantly the front. Obviously the only way to do this properly is having a separate listening room, nice job on yours. PITA is one way to put it, but in the end it has to be a labor of love to get you there. So worth it!

OP,

I read your topic, and quickly went to look at your system. Beautiful! I immediately saw the rack with the audio equipment and thought that could cause a problem. Racks with equipment confuse the imaging in their location. Then I read that was the nature of your post. Yes, a lot of work and expense moving that stuff around. But worth it. Thanks for sharing.

I particularly like how you have a home theater and two channel audio in the same room. That is the way to do it.

If you look at his system tcutter is far beyond the blanket stage.  Congrats, a stunning looking setup.

People laugh but the use of blankets to diagnose possible acoustic issues should not be underestimated.  A blanket over a rack or TV screen can tell you a lot about what to do next.
