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?

I have 6 pairs of DQ10s set up. I used some industrial strength metal racking obtained from Lowe's and modified them to accommodate all the Dqs. They are essentially stacked upon each other in three sets of rows. I am unable to post a picture here. If you send me an email to jenguillo7@cox-internet.com, I'll send you a picture and schematic of how they are hooked up. Essentially l amp is pushing 2 sets of DQ10s. Your amp must be able to handle the split load. Good luck.
You could always use a Speltz Autoformer to bring the impedance of two pairs operating off of one amp back up to double or even triple the impedance of a single pair.
Years ago, I heard 2 sets stacked, the top set was upside down. The guy made a bracket that molded around the top edges of the bottom set and the top set slid into the bracket, then had screws or bolts go through the side of the brackets into the speakers that stablized them fairly well. in this case, 2 sets were an improvement over 1 in almost all area's.
Find a pair of Audio Research D-76A's. I have a customer who had modified DQ-10's. I refurbished his amp and it sings!!!!It sounds better than when it was new because the new caps are much better than the stock ones.
