Default loudspeaker stereo imaging

When I listen to some speakers, the stereo imaging is amazing - you can
pinpoint each member of the band on the stage infront of you, yet other
speakers do not have this property.

From a design point of view, how do you go about achieving superb stereo
imaging?

Thanks for any explanations...

It has a lot to do with the positions of the HF and LF drivers and your
listening position. These result in errors which can muddy the stereo
sound field. The only real solution is to use dual concentric speakers.

Another strange point: speakers with two drivers almost always produce a
better and more sharply defined stereo image than those with three drivers.
Try a LS3/5a against a Spendor BC1 and you'll see what I mean.

I'll stick with my Tannoy Monitor Golds thanks all the same.

An exception to that is the ATC SCM300As (which have four drive units),
which produce the most incredible stereo image that I have ever heard:

But the centres of the drivers in a BC1 are further apart than on a 3/5a
- if you believe the dual concentric theory. Also, *in general* the
smaller the speaker overall, the better the image. Don't know where this
leaves the ESL57, except of course that it doesn't have a baffle to
diffuse the image.

Mounting any speaker flush in a rack etc as they do in some TV production
control rooms for appearance really does mess up the imaging.
