Subwoofers for Stacked Quad ESL 57's

I have a pair of HQD-like stands for stacking Quads with space for the tweeter in between that are not in use. I purchased them from someone years ago but never got around to setting them up.

please provide a way that I can contact you directly as I am very interested in learning more about them.

Thanks in advance

These really are fast enough and transparent enough to integrate seamlessly.
