Tekton speakers are currently on carpet, floors are hardwood over plywood.
Yes that sounds like typical suspended plywood floor used in most homes these days. If the bass sound too big and muddy, with detail lacking top to bottom, I’d strongly recommend trying isolation pads, like Auralex sub-dudes or something similar under the floor-standers. The floor interactions not only muddy the bass, but that muddied bass also obscures detail in the mid-range. It’s a fairly inexpensive tweak that usually pays big dividends.
