Welcome! Need support, you got it. Or share your ideas and experiences.
Question is mainly for learning/curiosity. I had a pair of 1.6 and Emotiva XPA-1's many years ago.
I recall in few instances there was panel flapping when watching movies. I was told at
the the time to set AVR for Full Size speakers and not to worry. It cannot hurt the maggies.
Is the flapping due to amp clipping which is hard to believe with XPA-1's or is it just one
of the planars weakness, hitting some precise resonant low frequency?
The best solution is to high-pass the loudspeakers (at 60-80Hz) and add a pair of good subs.
Not quite sure what you're referring to, by "panel flapping"? The mylar panels do flap - that's how they work!! :-))
But if you mean the 'crack' you get when the mylar sheet bottoms against the magnets (with heavy bass) - that's simply over-driving.
I have never experienced it ... in over 30 years of Maggie ownership:
* first with my IIIas
* and, for the last 10 years, with my 'Frankenpans' (which use MG-2.6 bass panels).
There will also be a noise if the wires or the timing buttons are lose. My 3.6 makes a noise while playing low bass at high levels. The smaller models have a rather high tuning which may be hit by some pop music. It is also possible to reduce the peak off the tuning frequency with a dip filter.
As long as you're not using an eq or tone controls there's really no reason the XPA-1's (I assume you're running two) should be causing 1.6's to flap.
Also the musical content could also be a factor as well, overly pumped bass by the engineers can cause problems with any system, but even more so with Maggies.
I've been running a pair of XPA-1's on my MG20s bass section going on 8 years now and I've never heard flapping (or any other artifact for that matter); and I've ran them BRUTALLY at times, enough to shake the walls.
Must have been either LFE or faulty panel section or both. I liked them for
Homr theater as well. Amazing sound details in the movies. The big problem is speaker placement due to it blocking the projrctor screen.
I've heard it with my MGIIIA's when playing New Age music with a steady stream of low bass. Never heard it after I replaced them with 3.6's.
