The phrase "patented speaker" in the clip was of interest, so here it is: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=3&f=G&l=50&co1=AND&d=PALL&s1=dahlquist.INNM.&s2=jon.INNM.&OS=IN/dahlquist+AND+IN/jon&RS=IN/dahlquist+AND+IN/jon The earlier one seems to be the DQ-10 -----Original Message-----

Your shared clip inspired me, so I searched for and found the whole document from which your Dahlquist article came from -- "High Fidelity's - Buying Guide to Speaker Systems - 1976 Edition .? (See page 28, starting with the first paragraph at the bottom of the left side column for the Jon Dahlquist piece.)? Looking through this guide today is a mind blowing trip down memory lane to 1976 -- when sound and speakers were king, and video was only an afterthought.? I bet I am not the only one who gets nostalgic looking through this guide, which for a $1.50 in its day was a real bargain and a treasure trove of information!
