Even then - almost certainly doubtful.

Why?
ok. ...for 500Hz

just for the sake of moving the discussion forward

then what about 600, 700, 800 Hz?

20 cm, 30 cm, 40 cm etc. above the floor?

any ...tip please?

I do not dare ask for any formula...

-the tip was already provided for reflective conditions vs direct sound: The closer in time, the less effect. The faster the onset, the less effect.

Not much else for me to say on time and "reflections".

Now there might be with respect to time, onset, and intensity with respect to Direct sound.

It might not even be primarily an interaural effect.

not the other way round? I mean: The slower the onset, the less effect?

Context: "reflective conditions vs direct sound:"

The faster the onset, the less effect any reflective condition will have to direct sound.

ie. direct sound dominates with a fast onset.

the new Shahinian Larc is the most flooder-like of all Shahinian line, just 34 cm high:

I've heard a few of their designs back in the early '90s - quite flawed in design and execution, yet still capable of *very* nice sound.

One of the worst parts about the design wasn't really a flaw - more of a choice. The use of less efficient drivers for a more broad-band response. It was sort of like Vandersteen meets Spica (except more of a radial configuration than Spica). One of the key audible characteristics was a thick midrange sound, lack of dynamics, and limited spl.

The real problem however is that Ohm's loudspeakers had similar limitations but overall were better sounding for a similar price. (..though most audiophile purchasers at that time couldn't deal with the lack of clarity in the treble from the walsh-type driver.)

The loudspeakers are to work on the floor the driver is only 20 cm above the floor and against the wall.
8" coaxial. Could work in flooderish manner when placed on the floor against room side wall, Beveridge way. Tilted top panel helps directing ceiling reflection towards listening position.

Why no one is using in living room ?
