I have a pair of DB1S for my computer/bedroom studio and have wondered if/when I would do the "+" upgrade I could also have them to be made active? (i.e. the current Flying Mole pack on the back.) I started with DynaudioAcoustic BM15s powered by a 4B-ST-Pro which sounded good, but, when I got my DB1Ss the bass from the transmission lines changed my perspective, the BM15s now sounded boomy. Recently I've gone to a 2B-LP-Pro that works well with my BP-25--to select my source. But, since it seems that PMC no longer makes their XB1-P--passive subwoofer with internal crossover--I only need to power the DB1Ss (was looking at a 3B or higher). But, as my rack is running out of space it would be more helpful to go active. I suppose I could go with some PowerPacs, but, not as convenient or less cluttered. Is this possible? Other interesting options? I did really like the 'full range' idea of paring the DB1S/TB1Ss with a Sub, with crossover, and still only need to power two channels.
