New Magnaplanar 1.7 delaminating and buzzing.


Why are new diaphrams buzzing and seperating from the frame?

I bought mine from Stereo Passion in Ottawa Ontario  Canada.  They arrived with brand new bagging, Styrofoam  boarding, inner cardboard  box, and an outer cardboard  box - brand new from the factory in Minnesota. There is no way after so many years of expertise  that an inferior glue should of been  used  and now I have to wait months . I'm  naturally an optimist  but I'm dealing with the trades and everywhere  I turn  people are dropping the ball and could care less. Just saying.

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.

I have, it's been 6 weeks and one was shipped for repair and lost in transit in New York and the other panel unglued from the frame just sitting and waiting for it's mate to be repaired, in a heated house. I bought them brand new in January and the diaphragms just started buzzing and shrinking back. This is unacceptable for  a premium set of loudspeakers costing $3200.00. They sounded  amazing for a month though! 

You're absolutely  right russ69. When the first panel was picked up by the seller,  the other panel looked and worked fine. Then in the last month just sitting there, the ribbon diaphram came unglued and now it has to be shipped back. The problem is the dealer and the  manufacturer are  incompetent . It took 1 month just to get the seller to organize  a pickup and that was on May 21st. Now that panel is stalled in New York and I'm being told to be patient. And now the other panel has to be shipped out separately as well. This reminds me of George Clooney in " The Perfect Storm".

Troidelover1499  -  why are you saying this? They are brand spanking new speakers and you are talking about the risks of buying used. Read first, process, then comment.

Hi ddd1,  as a NEW poster, as if that should make a difference, I meant no disrespect to 1499 but it was  plainly stated that they were brand new 1.7's. I didn't say 1.7 S - I said new 1.7. Of course they are are 1.7i's because they are brand new and  that's why in Canada they cost $3200.00 plus 13% tax. You assumed I stated 1.7s speakers. I was merely   inquiring as to anyone  else experiencing the quasi ribbon diaphragms  ungluing on new brand new speakers.

That's true  oddiofyl, a lot of great speakers but Maggies don't have a voice coil glued to the center of the speaker cone impeding  it's duplication  of the complex musical waveforms. The  ribbon is more free to shape itself to the soundwave  that's being generated. I use a subwoofer sometimes to beef up the lowest register but the 1.7I'S  are so transparent in the midrange and treble regions that the  recordings sound different than  I remember. Even the best Lossy formats sound drab compared back to back with the same CD recording. No other loudspeaker I've owned has so immediately  pointed out the lack  of detail from CD (1411kb/sec) to, say, standard Spotify (160 / 320 kb/sec). Pink Floyd "Wish You Were Here" comes alive on CD compared to "Remastered" Spotify or iTunes. These guys are all about data bandwidth.To my humble ears, no paper mache or  composite  cone that's nailed down in the middle is free to dance freely in producing all the subtle sonic gestures. 

Koestner, you don't know anything - for your information it's a 130' paperclip and it's not a shower curtain Mr.Smarty Pants, it's Saran Wrap. And we don't buy Chevy Novas here in Canada, we buy Nissan Pulsars - much more powerful. The only thing clearer sounding is voice to head technology but it's proprietary and controlled by the Military  Industrial Complex. Mic drop!
