Here is another quote below from The Audio Beat. The comment makes me wonder if the bass is actually a quasi-ribbon. Some of the post above commented that only the mids were quasi-ribbon on the 3.7. Does anyone know for sure?
"This time I was able to play music from my own CD-R, and the speakers, which even I could dream of owning, grabbed me by virtue of their coherency and, surprisingly, near-prodigious bass. Finally, a planar speaker with slam -– all without losing the glorious midrange and creamy top end that were hallmarks of the Magnepan MG3.6."
