powering two pairs of Dahlquist DQ10s

I had a nice pair of DQ-10s in the early-to-late 1980s and really liked them. About 1983, I installed the Randall Research modified crossover and drivers with nice results. With today's crossover components, wire and drivers, I would imagine that you could assemble a really nice pair.

Properly powering all four speakers with a single amp would be a tall order, to be sure. Get them away from all walls! not behind or on sides. Properly set up, they will image like crazy, with light, airy highs. I can only imagine how nice four would sound.....

Apfdirtdoctor...He disconnected the Motorola Piezo Tweeters and put all new film caps in the crossovers. I think he rewired them as well and replaced the woofers. OMG Enid Lumley. There's a name I haven't heard in decades.

Sorry Apfdirtdoctor, I didn't know of any articles. My old friend might have indeed read it. This was around 1980 to 1981.

I thought Mark Levinson stacked Quads, not Dahlquists.

As in HQD for Hartley, Quad and Decca.
