HELP - buzzing on Magnepan 3.6R; repair or not?


I was trying to sell my Magnepan 3.6R's which I purchased used from work (along with a pair of ML Odyssey's which I decided to keep. I was demoing them to a prospective buyer last night. I was playing deejay and threw on about 7 or 8 different tracks - chamber music, jazz, orchestral, pop vocal, etc.

I find them bright in my system so I wanted to make sure the prospective buyer understood that so I played a track that demonstrated that explained that to them. I said I didn't know how they rocked though so offered to put something on. I grabbed a White Stripes CD which has some extended bass notes on it. One of the panels started to vibrate/buzz. ARGH! Of course, I didn't know that when I bought them, but I received a decent enough deal from work that I can't complain.

So, I have two avenues I can pursue to sell them - one, sell as is at a steep discount (the prospective buyer is actually still interested in this as an option since he has no other components for his system yet so can wait) or two, repair them myself which would then allow me to market them as having a new panel and at that point I'd also now have boxes to go along with them. Which avenue of sale makes the most sense?

I left a voicemail at Martin Logan service early this morning (8:30AM their time), but did not receive a call back. Does anyone have any idea what it costs to repair this? I'm assuming this is not something that can be field repaired by me.

I have owned five pair of mags. I sold two sets to a local guy that will take apart anything. The mag 3's an older pair had a slap with a buzz he took the covering off the speaker and pressed his finger down on a staple and solved the problem, it was a lose staple.
It is a personal choice, I have also set two sets to the factory and had them repaired and, or refurbished, either way the factory has reasonable pricing.
I had the same problem on my old IIa's. I had spilt a coke on the panel, and I believe the mylar coverning the magnets delaminated.
Hi,

Just my two cents on this. I've got the same problem and Magnepan say I need a repair. Due to the excessive shipping charges that would apply when sending them from the UK, they offered me a repair kit for $40+delivery.

Unfortunately they can't ship it from October->April because if it freezes, the glue is ruined (!). So I phoned the Swedish Distributor, who have offered to send me some glue and explained how to repair it over the phone.

I'll update with how the repair process goes if I get a chance.

Regards,

John
Maggies may sound good when done right but I was never able to achieve this, and the many drawbacks prompted me to sell them.

That is not what you were asking about though. I believe your panel may be damaged. If you call up and talk to Wendell (and catch him in a good mood) he may be able to talk you through some rudimentary diagnostic steps.
there are tie wraps holding some stuff in the insides of the 3.6r speakers. Call Magnepan. They are quite nice and should fix it for free if it is really a problem and not clipping or bottoming out of your amp? If they are out of warranty you will have to pay the freight.

Good luck - get them tied down :-)
