Dimensions: 25’ × 30’ X large
Speaker positioning is very difficult. For a while I had my speakers 5' apart with the listening seat 8' away from each driver. 5' apart was kind of arbitrary: distance from the nearest wall was the only determining factor and the speakers were nearly 6' away from the nearest wall. I determined the distance from the speaker by moving the chair back and forth to get a sound I like. My preferred sound has a "headphone like" quality: where the speakers and even the room almost disappear. It is like being in an entirely different space. There was something about this sound that was not quite right, though. It was very "bubble like" and sounded a bit constrained. I felt like I was missing something I can only describe as "impact."
So I made a pretty drastic change by moving the speakers 6’ apart and put the chair 9’ away from the speakers. Changing position by just one foot made a big difference. It was like extending the size of the bubble of sound forward and more wide. There was also a nice addition of impact and power that I feel like I was missing. The sound coalesced into a more impactful package. My room constraints do not allow me to move too much further from the speakers but one day I will rearrange everything and give it a try. The downside is that there is a very small amount of shout in the upper midrange when played a higher levels (75-78 db peaks). I only listened for about 2 hours with this new configuration so I am trying to figure it out.
Suffice it to say, changing speaker positioning can update a system a lot more than changing downstream components.
