Are Magnepan MG-IIIa speakers problematic?

I was a Maggie dealer for 11 years, and sold several pairs of III's. They were NEVER problematic to me.
They are large, and with enough heat build up, you can misshape the ribbon tweeter.Plus the resistor, allows for audible phase shift, (to me), and my ear. It does, tame the high frequency enery. But that problem with the lessening of THD, and TIM over the last several years, the speakers seem much less a problem. So where was the problem, really, to begin with.
I will bet that with Halcro amps, they sound delicious.
Don't hesitate to buy them if you have room for them.
They are good speakers, worth owning. Plus, Magnepan, has ALWAYS backed their products.
Good luck,

Even though I am now recieving Green Mountain C-3's,
one of my most loved speakers were a pair of MG IIIa's.
They are magic driven with Spectron digital amps.
I never had any problems with mine to the day I sold
them.
I love Maggies!!

I have owned 3 pair of the 3.6r's, 1 pair of the 1.6's
and 1 pair of IIIa's. Never any issues..except tired
mornings!

Maggies have the uncanny ability to darg the listener into dreamworld. Yes, a properly setup Maggie pair can put many speakers many times the price to shame. I owned MG1c back in the 90's and the only reason I had to give it up was due to space constraints in my present abode, I do have a listening room albeit, I consider it small for accomodating the maggies. Many think Maggies do not have bass, I think that the best bass I ever heard in any speaker were the Maggies. Its squeaky clean and without any boom whatsoever.

If you drive them with a good amp (high current, high damping factor, with a flat response) of say about 150-200 watts at least you will get them to sing. Although Krell amps are fantastic but somehow I did not like the sound of the Krell with Maggies at all. I did like the Quad 606 II and Perreaux 3150 paired with it.

Magnepan has fantastic service and they can provide anything you may need. I reckon that if the speakers have never been serviced they may need the internal wiring checked and if necessary re glued to the mylar diaphragm. I did that to my MG1c's and the glue is available with Magnepan and does not cost much.

I was a Maggie fan for quite a while, had MG-IIs and then MG-IIIs (not the IIIA). I was driving them with a pair of Conrad Johnson MV75A-1s (vertically biamped) plus an Audio Pro B-250 sub. They had plenty of room around them and sounded fine. Then I heard a pair of comparively tiny ProAc Response 2s and suddenly the Maggies didn't sound as good. In an A/B comparison there was no contest and I sold the Maggies. But I remember them fondly and never had a bit of rouble with them.

It is an absolute must for every audiophile to experience living with a pair of Maggies.
