mapman, driver technology is important but not as important as how you use it. the woofer in the tsm is a morel and the tweeters are handmade to my spec by rennaissance audio and is an improoved version of the morel mdt28. it is the ren mst30.5. the disapearing act hififile speaks of has to do with the cabinet profile/dispersion, driver spacing, the very wide and super flat amplitude and its very continuous sound from top to bottom. it is imho, very expansive sounding.
