% Calculator - I know it's not rocket Science
Been playing around with speaker placement according to Jim Smith's 80% to 83% distance rule. I recently repositioned my speakers after some cleaning and spaced them a little wider apart. The sound change was really good so I decided to do a quick measurement to see where I was. I was really close to the 80-83%. To do quick calculations I found this little link that is a 3 way % calculator so you can figure it out simply in various ways.

Re: % Calculator - I know it's not rocket Science
I played around with that formula a while ago and my findings were that about 75% sounded better in my room with my speakers. Imaging in particular tends to be reduced if speakers are too widely spaced - and I rate imaging very highly!

Yes...it makes for a BIG improvement. Every demo I've heard where at Altaira was in the system, folks listened, and then the Altaira(s) were removed, and folks immediately demanded the Altaira be put...
Altaira or Gemini CGS on...
