I'm designing speaker stands for them from Philippine Mahogany, to match the cosmetics of my equipment rack. A design question is, should the stands have a solid top plate or should the speakers' bottom panel be exposed to the room? Most speaker manufacturers' photos of stands for lossy cabinet speakers show an open steel frame with contact to the speaker only at corner points.
I think the theory is the bottom panel resonates like the other panels (by design) and adds to the overall sound in the room. A flat plate would choke that contribution off.
I use Sound Anchor stands specifically built for Harbeth speakers. They are three post stands, not there is no full bottom plate…just the pillars and a bar between them. All other things being equal, I would leave the stand open.
Congrats on the Super HL5+. I think you will be very pleased.
