I trashed the screed I wrote because Mike said it all. This is smart;
they're John's speakers, so only the sound at his listening chair
matters. If John wants a benchmark, independent of a listening
position, a good measuring distance for '57s is also the minimum
listening position of two meters, two long paces. (1) It would probably
be smart to raise the bottom rail of the '57 at least 14in off the
floor; it might still need tilting back; stacks of paperback books are
handy. For years I kept mine on a steamer trunk (full of books, zero
resonance) with the bottom rail 24in off the floor which put the sound
level with my ears when seated in an office chair with my feet up on
pouffe. Alligning '57s correctly can account for an amazing amount of
"lost" SPL restored to your ears.

You may be right here about the alignment & positioning, which I ddn't mention
in my reply on the subject.

But at 3 or 4 metres which would be possible in the large rooms of the rich people

who mainly bought ESL57, the height may not matter if the path to the ears is
uncluttered.

And do not dipole speakers have queer response due to reflections?
