Speaker distance

Heh-heh

unreceievdeogma-  I have been playing with placement with my Altec Valencia 846's. I tried a basic 40/40/20.... speakers pulled out 40% of room length, listener 40% from speaker, with 20% remaining length behind listener. This didn't work at all for the Altec's, which I believe shine with plenty of distance between listener and speaker. That 40/40/20 had me way too close in my 23 + foot long room. I tried the Verity formula noted earlier in this thread, and liked the result from the room width divided by 3.6, which situated my speakers 41" from the side walls. That was using my 148" width of course. Now I'm going to play with the rest of that formula which uses the ceiling height to determine how far speakers are pulled out from rear wall. In my case my 8 ft ceiling dictates they be pulled out 4.96 ft from rear wall. Currently in my (23+ ft) room, I'm not too far removed from the suggested 4.96... Should be interesting, but so far very positive going to the 41" from side wall....I had them 44" from side wall before I began playing with the Verity formula. Thanks for posting that. I always enjoyed the Parsifal, and never noticed the Verity formula. Perhaps it wasn't available way back then.

I'm getting a little confused. It seems to me that some posters are referring to the wall behind the speakers as the back wall and some are referring to it as the front wall. 

Also, wouldn't rear ported speakers require a much different approach than front ported or unported? Canton recommends that their front ported towers be placed with the REAR of the speaker between 12" and 20" from the wall behind them.  

Every speaker manufacturer has a different design, Driver materials, toe in and raking requirements. One must consult the designer to really understand the strengths and the negatives of the particular model of speaker. Some things are simple fundamentals for all of us at Sunny's, they are that both speakers must have the same angle in raking. this insures that both left and right speakers have the drivers firing equally if it's a one box speaker. This is a good place to start. Then one must find the rooms zone of neutrality. Mark this zone. then start working carefully documenting the progress of what you hear. This allows you to go back and verify what you heard. this allows you to grade where your speaker sounds best in the said room with the exact gear you own. Figures , charts and numbers cannot be uniform as rooms are all different, flooring materials affect speakers too. Most of all make it fun, involve a group of friends and share your passion. It's all for the music. Keep listening.

@2channel8, unfortunately it is confusing. I learned the wall you are facing, the wall behind the speakers is the FRONT wall. The rear wall is the one behind you.
