Equilateral triangles/ monitor placement.

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.

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?
