So -- I just saw this link Somewhere Else. It is from 1982, and is (apparently) widely referenced in the places you might expect to find such things (ahem, www.lansingheritage.org ahem) -- but it was new to me.

So, I thought I'd share it here. Page 24 of the PDF (labeled page 26 in the periodical).

I'm a fan :)

Another article from Art Dudley that sort of puts the Duplex in context:

    "carefully, cost-no-object–engineered to show producers what, exactly, is coming down the mike feed. You really want to know what's hidden in those record grooves? These will show you."

    I've never had the opportunity to hear these. Sounds intriguing.

    Per the link above, Art Dudley has him on his list of five loudspeakers you should hear before you die :)

    Art's in the midst of a two-parter on rehabbing a pair of 604Es in Stereophile, in fact.
