Only had these for 3 months, and need to be sold I'm afraid- my Plinius simply isn't butch enough for them and I can't afford to upgrade to a much more powerful amplifier. Very musical, accurate sounding monitors- used through many studios. Made of Alphacrystal Stone- acoustically dead cabinets so the sound is as uncoloured as it comes. They even do bass. Imaging is simply jaw-dropping. Come with matching stands, which make them about 1m tall and also with instructions, graphs showing flat freq response and boxes. Great condition bar a minor chip at the top left of one speaker and a chip at the base of one stand (not visible) where the screw thread is for the spike only 3 years old, and were £2500 then. shall we say £1250 ono collection and audition strongly advised as they are heavy
