Depends on how you mix. If you're mixing in the box, then the expensive part is the room itself.

Then why not mix at home from the beginning instead of carrying the studio home?

@graaf concerning ceiling flooder and "mini wideranger array"

The "phase controled mini wideranger array" could be used to
investigate the ceiling flooder approach in a systematic manner.

Radiation pattern could be varied from simulating

a "small fullranger"
a "big fullranger" with radiation pattern narrowing at even lower frequency
a "constant directivity" pattern.

An adjustable delay for the woofer could be given listeners at
hand to adjust a preferable delay dependent from the setting.

If the listeners choose no delay, you know that it is not needed.

Just a thought experiment. Thought experiments are very cheap
unless done real.

You mean "not essential" for the "ceiling flooder spatial effect" ?

But if there is an effect different from an omni source it must
be due to radiaton pattern ... or has my logic left me somewhere
in the depth of this thread ?

Or do you mean spectral energy distribution is not essential ?

Of course the change of the polar response with changing frequency is important, but what does that have to do with your talk about voice coils and so on?

A fullranger firing towards the ceiling is not able anymore
to compensate falling VC velocity
- which is the reason for falling acoustic power with frequency-
by beaming at the listener to exhibit flat sound pressure response.

It is like measuring the sound pressure off axis. You get a strongly
falling pattern for a t y p i c a l driver.

This may rise the need for compensation, when a typical driver
is used for that purpose. That is all i want to say.

If not, here is some reading stuff about an other strange system:
Andrea von Salis - The reproduction system

I posted the speaker placement earlier. I've been to that site before but never tried that one so I can't say much. Same basic concept except I don't have any euphonic knobs and mine probably works better In that regard I agree with what Markus was saying earlier that these things should just work and not need a bunch of tinkering and knob turning. It's pretty easy for me to set up situations with a knob that can drastically stretch, warp, or smear the imaging the hard part is giving the user an "un-distort" button that just works.

You mean this coloured picture with the "hexaphonic" thing?
And the decoder?
