Hey Mike, I'm from Seattle too, well, Tacoma.
Can you elaborate on your reply? I've only heard of the 12's and no one here seems to know anything about them.
I was beginning to think the DQ-12 was a typo, but they do exist out there in addition to the DQ-20. They are configured more like a DQ-20 in that they're a narrower 3-way with a more sculpted open baffle for the mid & tweet, like the DQ-20. I don't know anything else about them, but if you google, you'll find discussions about them on Audiokarma.org and other places.
Not that I know you're in the neighborhood, I strongly recommend you make a field trip to
Hawthorne Stereo in Seattle. As you can see, they have a great selection of used gear, and always seem to attract great used speakers. They often have a pair or two of DQ-10s and 20s around, through right now they're out. Notice, however, that they currently have several models of ADS under discussion--780 II, 810, 910, L-1590, and the M-12, which is probably the most speaker for the buck in that list, and would obliterate the DQ-10.
Seattle_Mike: What you say about the DQ-10's build quality vs. modern is very true. The build quality of the ADS L- and M- series, however, match or exceed 80-90% of what's built today, and the previous models do as well, except for those cheesy '70s-era spring-loaded terminals. Even McIntosh amps had those back then, however.
