I've got a pair of Klipsch Synergy B20 bookshelf speakers that, for the last year, have been sitting on the floor for lack of a better option. I finally got to build them some speaker stands using the design on this site: http://www.tnt-audio.com/clinica/stubby_e.html. The increase in my enjoyment has been huge. Now I'm wondering about the little rubber feet that came in the box with the speakers--I never put them on, since the speakers were only sitting on carpet. Now that they're on these stands, will sticking those rubber feet on give me better sound, worse sound, or no difference?
