Classical music - not excessively loudly but of course orchestral
climaxes can be loud.
Digital sources - not vinyl.
Room 11' x 13' x 8' high (rather small probably for the speakers Focal
JMLab Chorus 714V Power handling 130W max (90W nom) Sensitivity 91dB)

An orchestra even in the auditorium can peak at over 120dB.

Do you have a reference for this? I have been looking for credible
sources for peak orchestral SPLs in the auditorium for a long while.

I have quite a few health & safety measurements of very good credibility
inside the orchestra and a few at the conductor's rostrum. However I
have only semi-credible figures for places in the auditorium and they
only go up to 109 dB SPL.
