Unity Audio "The Rock" Active Monitor

Searching for the world best small active monitor, I came across an interesting product from UK's Unity Audio.  The Rock is available in two version, Pro audio and Hi-fi, with the Hi-fi version slightly nicer looking with black gloss finish.  It's a sealed-box design with internal amplifier module designed by E.A.R's Tim De Paravicini. 




Front baffle is Corian bonded to plywood cabinet.  Corian is a very dense, stone like material, this improves the rigidity of the baffle.  Folded ribbon tweeter and 7" pulp fiber woofer are from Germany's ELAC.  The ribbon tweeter's is flat to 50kHz, great for high resolution music.  Internal wires are cryogenically treated.  Internal amplifier is 100 watt discrete bi-polar low feedback with separate transformers for each drive unit with no crossover networks (30 watt to the tweeter and 70 watt to the woofer).  Sealed box meaning placement would not affect bass performance as in other open-box ported designs.
