Here’s a way to adjust if you have a home theater receiver laying around with room correction.
1) hook up that receiver to the speakers. If it can’t drive them, use it as a preamp.
2) run the room correction
3) right down the adjustments it made. Pay close attention to high and low ranges!
Write down the adjustments
Move your speakers inward an equal distance , repeat calibration. Look at adjustment screen. If it adjusted more, then your going the wrong way, try inward more.
! The goal is for no band to be adjusted more than 3db!! You might need to do stuff like put a rug on wall to Help things out.
Once you have them optimized, remove the receiver , banish it back to that shelf in the garage.
Although I have esl speakers, I think setup is similar for Maggie’s . Get them dialed in, room treat if necessary. Keep them at least 3’ away from walls. It is possible that you won’t need a sub if everything is dialed in just
My current method- my 24 daughter has excellent hearing. I run just one speaker with music , she sits in sweet
spot and while I slowly turn speaker , she says “better” or “ getting worse”.
