For starters, I would think DQ10's should not be mounted on a wall for best performance.
They are excellent speakers and image well, due in part to their semi open baffle design.
The manufacturer supplied them with low stands like the original Quads, and for an extra charge, slightly higher stands.
So in either case up off the floor and typically a least a few feet from the walls.
From there I don't know how you would "stack" them, but this has been addressed in other threads for Quads and Magnepans. I would guess that stacking them vertically like Quads might be best.
The DQ1W was a matched subwoofer which could be used singly or in pairs, where Dahlquist also made an easy to adjust active crossover you might also find on the used market.
That made it easy enough to use one amp for the woofer and another for the panels, but I will let others comment on vertical or horizontal biamping for two sets of panels alone.
Good luck - classic speakers well worth the effort.
