Should I switch to a larger room?


My current listening room is 10x12. Since I live alone, I could make my master bedroom my dedicated listening room.  It is 13x18.  Switching rooms would be a PITA, but is it worth doing?  My speakers are MMGs and they will be getting the Peter Gunn mod in the fall.  I do have some room treatment from GIK Acoustics delivering in a few weeks, but what I ordered was based on my 10x12 room.

The measurements more closely align with the magic quotient of 1.6. Yours is 1.39. I'm not sure how much it means. But It may be worth a try.
@artemus_5 Magic quotient of 1.6?  Do you happen to have a link where I can read up on it?
