powering two pairs of Dahlquist DQ10s


I just got a second set of Dahlquist DQ10 speakers and am wondering how to use them.

I have he first set mounted on a wall, powered by a van Alystne mod Double Dyna 400. Somebody suggested to me that I could use the second set on stands underneath the first and biamp them.

This is new territory for me. How exactly would this work? Is it also possible to power them both with the same amplifier?

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.
