I looked at the Legacy Signature and the enclosure looks close to minimal allowable for the woofers. Are you looking for a smaller speaker which likely means smaller woofers? Seems that even bookshelf speaker stands have similar footprints to floor standers.
Your 75 watt MC275 VI tube amp will drive a lot of great speakers. What's your budget?
