Speaker placement


I've read a lot regarding speaker placement but I do have a question. If someone states place the speakers 3ft from the wall where do you measure it? From the rear of the cabinet or the from the driver position?

Thanks

I have a feeling most folks probably assume that the distance between speakers should be around 6-8 feet and never get around to experimenting with shorter distances. In fact, however, the correct distance for most speakers in most rooms is more like 4 to 6 feet. IIRC the issue of the distance between speakers is discussed on the XLO test CD.
Geoffkait, How do you come up with what the 'correcty distance' might/should be without reference to room dimensions and the distance of the listening position from the plane of the speakers?

Personally I think many folks don't properly give the set up position of the listening chair credit for its substantial contribution to the sound you hear, both soundstaging effects and effecting a linear frequency response by minimizing the effects of room and set up induced nulls and nodes.
Right, Newbee... it's about room dimensions and listener's position.

Xti16; speaker placement with regard to side walls is very important.

Geoffkait - I had my Dyns approx 5ft (with no toe in) apart sitting approx 8ft back so I do mostly agree. Mostly because Raidho recommends 9ft apart. Right mow I can only get them 7ft apart (with about a 30 degree toe in). Tried closer together but it kills the sound. The Dyns have a very wide dispersion while the D1's is fairly narrow. Both give a nice wide sound stage from the sweet spot - with the Dyns having a wider sweet spot. Like I said 2 very different speakers.
Newbee, the answer to your question is the XLO Test CD. The speaker placement track allows you to find the very best speaker locations in any room, independent of room dimensions, room acoustic treatments, if any, and type of speaker. Attempting to find the absolute best locations by ear is a pig in a poke because you can never really be sure you have actually found the best locations.
