Anyone hear Dynaudio subwoofers

Thanks Bigbucks. Which speakers? Can the internal crossover be bypassed to use an outboard bass management unit? HOw big is your room?

Thanks, CT for thinking of me.  As of now, I am running active bi-amplified OB speakers w 2, 10" woofers on each baffle, driven my 200 wpc crown class 2 amp.  Haven't cheked it out w pipe organ, but no sub needed for any other use, IMO.  But I appreciate the time you put in to your response.
