Put Herbie's giant pucks under spikes of Legacy Signature SE on suspended hardwood (parquet) floor. Sound appears more open than when on rubber feet, though this is preliminary and more positioning experiments are needed. Fortunately the pucks allow this to be done with no more effort than using frosted silicone mats, which looked a bit strange. On on the other hand, given Legacy's inexplicable indentation of the feet from the speaker corners, the flared Herbies produce the visual effect of refined cabinetry on silly little duck feet, ready to waddle off at any moment. Final judgment reserved until one of my candid and witty friends gets a hard look at this setup. (Herbie wanted a photo, but I can't upload to their response form).
Herbies Pucks floor spike protectors...
My very heavy speakers came with 3 spikes per speaker....the floor is travertine tiles. Use or not use? (not for floor protection, but for sound improvement)
