I have been demoing a pair for each speaker for 10 days. They are really great. Will be buying them when the demo period is over. Also will be buying a pair of their C-MARC rca interconnects.great products.As for having them on the floor I am using a pair of the Command hangers that i have taped to the back of my speakers that keep both the speaker cables and the Firewalls off the floor..Easily removeable if needed.
