This speaker offered some of the most dynamically cohesive sound that I heard. From what I learned, the company uses it's own proprietary drivers with great care given to the crossover and enclosure design. What ever they do - it works and to a great extent. The finish on these speakers was superb and quite beautiful, matching their wonderful sound. When played loud - these speakers gave no indication of breaking up or losing their composure. They simply let the music wash out into the room and pour over anyone listening.
