New Magnaplanar 1.7 delaminating and buzzing.


Why are new diaphrams buzzing and seperating from the frame?

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. 

Magnepans are fine sounding speakers, but don't confuse a 50 foot paperclip, glued to a shower curtain, placed in front of some magnets to be 21st century engineering. Especially when they require the power of a super nova.

Any company can have a bad run of parts, a batch of adhesives that don't meet specs, etc.  One of the best motherboards I ever used was an ASUS, but after a year it starting having mystery problems.  Turned out for a period of a few months of production, all the certain value outsourced capacitors were bad and would "pop" over time. 

ASUS is still in business and makes great motherboards. 

Look at Honda and others with great engineering. Even they were bitten by the airbag issue from another manufacturer and had massive recalls.

I'm afraid it is all just a part of any products that are manufactured, no matter how well engineered, no matter how well built, there can be and always will *sometimes* be issues.

Jana Dagdagan did a video a few weeks ago (on John Darko's YT channel) at Magnepan's factory showing how the LRS+ were made.  Everyone there seemed to genuinely be interested in making a quality product and were proud for doing so. 

@fsonicsmith , I guess I’m just a dumb ass. But when you’ve had as many concussions as I have, and you take all the meds that I must, you just try to be nice to people. God Bless my friend.
