RE: Building a room for my Magnepans

to better break up modes, you might consider replacing roxull on 1 or 2 sides with 2x gypsum board.
Also, a 3:2:1 ratio is NOT good. Even multiples of length promote 'bad' vibes.
It also might be advantageous to do an OFFSET STUD wall where you will lose 2" of width while having 2 stud walls. Each is offset from the other. BTW studs are typically 16" on center not 8".
Between the studs, you can weave sound deadening material. I don't have a current link, but I saw some very heavy stuff in sheet form.

\Please check out 'room mode calculator' and enter your values and look at the frequency spread. You might be fairly close to a PHI ratio'd room, which is a reasonable starting place.
