I own 3.6Rs which have been totally redone by Magnepan in Feb20. I have done a lot of work positioning these speakers in a dedicated 35'x19'x9' room. I have also done a lot of research on how to optimize them.
- set them up on Mye stands.
- at least 4 feet from front wall. Preferably a minimum of 7. Front wall needs to be diffusive.
- back wall should be absorptive
- treating first point reflection is actually not recommended from maggies. Only used to attenuate high frequencies if needed. I have since removed my absorptive panels from the first reflection as shown in the picture below.
- choose your listening position to minimize room modes below the schroeder frequency. Speakers should be 7 to 9 feet apart and lp approximately from equilateral to 1.5 times that distance.
- slight toe in- when you move your head away from center of LP, sound field on either way should become brighter, louder, and diffused.
- ensure LP height matched middle of tweeter height. Ensure panels are leveled vertically.
- I recommend Bryston monos for amplification
- add subs- open baffle, servo controlled are the best match for Maggies
- DRC- stay away from maggies internal crossover frequencies. I only eq my subs between 20hz to 100hz. I crossover at 100hz. Bi-amping is very tricky with an internal crossover of 200-250hz.
- I am very lucky to have walls made of porous cement blocks which match the manufacturer voicing room.
I have owned box speakers before (Dunlavy SCIVas) and the Magnepan, once set up correctly, blow them away.
