inter-speaker distance

Posted by: davidf on 16 December 2000

Just today I spent a couple of hours changing the distance between by speakers (Linn 5140`s). Previously, my speakers were about 9.5 feet apart and now they are 8 feet apart- along a 20 foot wall (the short wall if you can believe it). I believe the sound has tightened up-more of a single wall of sound. I would like to know if there is a general rule as to the sound traits that occur related to inter-speaker distance. That is, what type of things are likely to go wrong if the speakers are too far apart, and conversely, what are the problems if the speakers are too close together? Are you better to err one way or the other? Rest of system is lp12/ekos/rega exact/ cdx/nat01/82/supercap/250 and linn 5150 sub. Thanks,david.

Thanks alot richard, that was an excellent post. I sit about 9 feet from the speakers, so I will keep them 8 feet apart for now. It is a big hassle for me to move them due to the presence of linn Skeets under the spikes which I adhere to the hardwood floor with double sided tape so there is no movement. Each time I want to move the speakers I have to remove the adhesive from the floor and then of course I have to re-level the speakers which itself takes a bit of time. I find the skeets an excellent way to couple the speakers to the floor (as well as my equipment stands as well).
It is amazing how much difference can be made my just moving the speakers a bit closer together. I have found that one has to live with any kind of change in the equipment position for a few weeks before deciding what position is best. Never make snap judgements! Thanks, again. David.

Sorry chaps, but I don't think there is a formula.
For years I have followed the accepted 'ideal' triangle placement, with poor reslts in my present 22 foot by 10 foot rectanglar listening room. My speakers are Wilson Audio Watt/Puppies. Recently I decided to defy convention, turned the whole room around and placed the speakers at each end of the 22 foot wall playing to a central position against the opposite wall. It shouldn't work but the improvement has been huge.

Clearly there was some kind of standing-wave problem or similar with the conventional set-up, but there is nothing odd about the room to have predicted this.

My advice is to try all the extreme positions in case you are missing a magical placement

Hey Richard, not a bad post!

And how’s that CDX/82 combo getting on? I just upgraded from a 72 to an 82, and while the difference wasn’t much to brag about at the beginning, the 82 really began to sing after about 4 days hooked up to the mains. Amazing bass, the space around the notes is much blacker, and string instruments have begun to sound like the real thing at last. I’ve only heard a “cold” 52 once, and I’m glad because my savings have been depleted enormously since I fell for Naim.

David,

Inter-speaker distance: I suppose while most of what Richard said applies in most cases, the room and the type of speaker probably account for a lot … I got good results with one of those test CDs by XLO – it has an out-of-phase track which you can play while you move the speakers around. When the out-of-phase effect is very pronounced, your speakers will be in a position where normal music will sound focused and coherent.

Richard,

Sorry, my memory is going downhill – just one of those things when you get past 30. Forgot to mention that my 82 is used, so it’s basically run in. When my 72/Hi/140 were new, the sound kept improving over the course of – I kid you not – 2 months, so the grin on your face may become wider still ...
