As most will know, speakers like the Spendor BC1 sound horrid if placed on
the floor. Raising them on a stand with air between the floor and the
speaker sorts out the bass end nicely.

In practice, the stand height places the tweeter roughly on line to the
ear when sitting down.

But is there a formula for the ideal distance from floor to speaker based
on cabinet volume or whatever? Or is it just 'enough' and more makes no
difference?

Speaker height was always regarded as that necessary to
place the speakers at ear level when in the listening
position.

Agree about the BC1 - but still a very warm speaker.

**No. It is entirely dependent on the whim of the designer. Most (sane)
designers organise things such that the HF driver is close to normal ear
level. Some deigners place the bass driver close to the floor to obtain
'room gain'.

** One notable thing about the human head is that the eyes and
the ears are at the same level.

With most speakers, the tweeters are the predominant source for
sound location - so they set the width and height ( above the floor)
of the sound stage.

Most folk like the sound stage to be right in front of them when
seated in the middle of a stereo pair, as it helps them imagine
the performance. Same goes for TV and cinema screens too.

Eye level is the thing you set tweeters at.

Speakers can be quite directional at the mid/top crossover frequency if
the two drivers are too far apart, and they might be better tilted back
a bit. Not as bad as listening to ESL57s and moving your head 6" to one side
but there might be a difference.

And of course if you have a party you need taller stands to put the tweeters
at ear level when standing up.

I'm puzzled why some manufacturers put the tweeter diagonally to the
same side of the midrange on both speakers of a pair. It blurs the
soundstage.

Yes that is a strange thing to do, even my old Dentons are mirror images.
Maybe they never intended them to be the way up many put them for many
speakers.
I have one bass speaker to help make it extend lower, but the effect is
very location dependent. In an experiment recently it actually sounded
better out in the hall!. Not entirely practicle i grant you.

** Huh??

The treble, mid and bass panels on an ESL57 are concentric, vertical
strips.

Of course the virtual image shifts IF you shift - that is how stereo
works.

** Really ?

There is simply no sound stage or virtual image to be had when folk are
milling about, boozing and chatting.

Makes Bose 901s the perfect party speakers.

With the BC1, the quality of the bass seems to change dramatically if it's
on the floor. More quality than gain? Hence the question in case there was
more to it.

So as a rule, midrange and tweeter need to be as close as possible?

I guess it saves them the bother of having to make mirror pairs whilst
allowing them to tweak any effects due to cabinet edge scatter. Perhaps a
sign that they aren't that bothered about stereo image.
