I had the SDA CRS model for about 10 years now my friend has been enjoying them for the last 6. The sound was always pleasing and nicely balanced, and loud is one wanted. They were an easy load to drive, and a very easy to live with speaker.
There was some trickyness in the crossover to try to make each speaker produce stereo effects using two drivers a head width apart and feeding some signal from the other channel with appropriate timing processing. The effect for me was a very nice prescence, much like live particularly with small groups in intimate recording settings. Set up corectly and properly driven they could deliver an emotional impact with the the very best.
