Thanks for the input. Indeed I am in the process of setting up the speaker locations and have a lot of flexibility in placement, but am thinking and planning ahead given the new circumstances. The Nobosound springs sound interesting, but the speakers and stands weigh about 120 pounds, which I think could be a problem. I'll need to explore a few options.
I guess CD318 captured my concern that wasn't well articulated, which is that the woofers move more and could be more prone to smearing. But I guess I won't know until I try.
CD318 - you didn't include the video link.
