New Magnaplanar 1.7 delaminating and buzzing.

Call Magnepan and ask about your repair and what you should do with the other one. I'm not sure how the new design can buzz but see if you can get them to clarify the issue. 

Thanks for the good advice guys - as far as sound performance and clarity, I am more than amazed at these 1.7’s. They may not be the best deal or the best in impedance characteristics but everything I audition on them just reveals so much unstrained detail. My amp never falters and I couldn’t use near their volume potential in my 13 x 17 room. The problem is that the vertical adhesive strip on the woofer side of the front diaphragm just came unglued and the vibrating panel isn’t held taunt to the frame. Bad epoxy or newby oversight - something is compromised here. What a shame because there’s a lot of steps needed to correct this and so many formerly conscientious producers of everything have stopped giving a crap anymore - if you know what I mean.

It sounds like both panels need to go back to Magnepan. 

@barmeg

if you are on the west coast - i realize you may well not be - i have my set of 1.7i’s that i will likely sell in the not-too-distant future... i am just making absolutely sure my 3.7i’s are keepers (and i am becoming more certain each day that they are...)

pm me for details if you are interested and are close enough to pick up, i don’t want to ship them, will sell to someone nearby when time comes - they are in perfect condition, grey/cherry, no issues whatsoever, with magna risers

just have the seller give you your money back on the problematic set you have, trying to repair etc etc... it is too bad magnepan is having these issues now...
