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.

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.

It also depends how old the BC1 is - the originals were two-ways. BTW,
Lowthers are essentially dual-concentric two-ways, and IME they don't
image worth a damn!

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.

Some of the finest imaging I ever heard was from flush-mounted
speakers. Think about it - there *is* no diffraction smear from the
baffle in a flush-mounted speaker.
