In my experience the best sound, not considering placement for bass excess or reinforcement, I have always enjoyed dynamic speakers with the chair on about a 6 to 5 ratio, that is if 10 feet apart, then you head would be about 12 feet back. In your case with your speakers 6 feet apart, your listening position would be 7'2" back. The further back you go from there you will lose fine focus as the reflection points in the room start to intrude on the direct sound. Toe in or out can help restore or deminish focus lost in moving further back. Soundstage size can also collapse, especially at low volume. If you go back far enuf you almost have a far field experience, which may not really be all that bad a thing, assuming you don't miss the fine focus thing. Start experimenting without delay.
Maximum distance from my monitors
OK guys, here's the scoop. I have my speakers set up in a way less than optimal position. I'm sitting in a pefect triangle, however, I'm just six feet from my speakers which are also 6 feet apart. They are 6" from the back wall and my listening chair is right against the wall that's behind it(chair). Terrible!, I know. Finally, (diamond stud earrings helped, of course), my wife is going to let me move my system to the other side of the living room. I'm going to place the speakers (the best I can do, given my room dimensions) toed in slightly, 2 feet from the side walls and 3 1/2 feet from the back wall.---6 feet apart. My listening chair will have 3 feet behind it before the wall. I'll be 12 feet from the speakers. Is this too far? Will I be giving up anything? I can get closer, but that will require moving a chair closer, when listening, to make that happen. The, chair, although movable, has to remain where it is for optimal living. Not listening, though. I'd appreciate feedback on the distances. Given, where my speakers were (on the long wall, as well) and where they will be now, I'm excited about the anticipated improvement, regardless. SOUNDSTAGE!, alone will do it, for me. I'm just waiting on an electician (my electrician loves me. thinks I'm nuts, of course) to put in the dedicated lines/Hubbells; and then I'm off. Should be a day or two. I hope I gave you enough info. Thanks in advance, my fellow audiophools. peace, warren
