Superficially, at least, there's nothing particularly unusual about the Sttaf, with little to distinguish it from, say, the Teufel Ultima 7, or Kudos X2. It's a simple two-way floorstander, based on a 140mm bass/mid driver with a 95mm diameter flared and doped paper cone. This is loaded by the larger, upper section of the enclosure and a rear port and crosses over using a second-order network at around 2.5kHz to a 25mm fabric dome tweeter.
