The Dynaudio BM6A's are little monsters. Flat to 40Hz, with mucho useable crunch below that, depending on wall proximity. I owned a pair. I know. These puppies should be chained to their stands to avoid biting the guests. 100/50 watts to each driver... I loved LOVED those speakers. The newer Dynaudio BM5a are more livingroom friendly, and no doubt Dyn has learned and applied much. This experience is what sold me on using refined tube amps actively amplifying wideband drivers. The effect is VERY similar.
The ADAM series is even more interesting, with the Heil-derived ribbon tweeter, and German design/engineering. The little 7a?? looks wonderful, with carbon fiber woofer, and ribbon tweeter, high speed switching amp, and lots of control over function.
