I have a pair of Mordaunt-Short 906 towers that are about 34" high. One of the speakers is partly obscured by the arm of a couch. With my room layout it is impractical to move the furniture, so I'm wondering if anyone has ideas on what to use to raise the speakers by about 2-3 inches. Does anyone manufacture stone or wood platforms designed for this purpose? BTW, what is the ideal tweeter height (I know it is supposed to be ear level, but is there an ideal measurement)?
