The equilateral triangle is not an obligation.

A long time ago, a fashion was cross the speakers one meter in front of the head.

The practice are numerous.

Jbl advised for the lsr 6332 a angle between 30 and 50 °

Yep! Very true. And Boggy has often said that he generally uses a toe-in of anywhere between about 25° and 35°. I'd agree with that.

Debating whether the engineer actually sits at the tip of an isosceles or equilateral triangle is beyond the actual point and not really interesting.
1000%.

The equilateral triangle exists in the room and the engineer is positioned inside of it. The triangle is formed between 2 speakers and an invisible apex, which can be marked on the floor with tape as a reference point when doing measurements or positioning the desk. I usually do this and take acoustic measurements with the mic positioned 12" forward of the apex.

Personally I never vary the speaker angle of the primary monitors. Secondary reference sets often have to compromise in their position (particularly if you're being smart about their interference with the mains/primary reference set, but that's life.

All the room variables are set within the following simple time limits:

Without EER variable: lim t(1)->t(1+n) since direct path speakers to ears is the fastest path so any reflection always arrive in t(1+n)
Haha, I couldn't decipher this Thomas. Could you rephrase / elaborate here?
