And which "much more expensive" speaker system outclasses even the
second best Lowther?

Here is a classification of the best speakers ever made:

1. Quad first series ESL of 1957. The speaker designer's reference.


Yeah, Planets sounds so grand with the Quads.

I'm sorry you're poor, Maggie. Go along to your plutocratic chum
Ludovic Mirabel and listen to his stacked Quads. You get 3dB extra
every time you stack another set of Quads. Four stacked-63 per side are
just about right for totally anti-social volumes in any room up to 44ft
long; more look like showing off. Or a Bessel Array with 7 or 11 ESL,
depending on how long your wall is and how much space you want to give
to amps to drive a Bessel, makes a very impressive stereo wall of
sound. Nobody could make dumb cracks about Uranus before such a wall of
sound.

With stacked ESL57, would you not get a line array driver effect,
with sound being radiated in vertical wave fronts rather than tending to be
spherical?
This is suppoed to aid imaging I am told, but having never
used a line array speaker or stacked quads, then I really don't know if
claims about
imaging are correct. Does a line array make a violin sound like its 3
metres high
and played by a giant?

Suspended line array dynamic speakers are increasingly popular due to
sensitivity gains
and variable directionality especially with PA systems coupled to PC
controlled
speaker directionality so the sound at the back of the audience can be
adjusted to be about the same loudness
and F response as at the front row.
At a recent cultural festival gig in town last summer line array systems
were used and were
very much smaller but better than walls of much larger "normal" speakers
each side of the stage,
and I had little urge to use ear plugs necessary at such events.
