[QUOTE="Ampdog, post: 849564, member: 144"] General question to those with experience: In my earlier days 'active' loudspeakers mostly implied that the driver itself is actively involved in the NFB loop of the amplifier, as in motional feedback. [This is where the driver itself is involved in the amplifier feedback loop in such a way that unevenness in the cone radiation itself (thus acting in a manner of speaking, as an 'internal microphone') is compensated for by the amplifier.] From descriptions it now appears that it simply means a loudspeaker containing an amplifier and driver in the same enclosure, without involving electronic control of the driver(s)? Secondly I notice that in bi-amplification (i.e. with separate amplifiers for l.f. and h.f. drivers respectively, each with its specific band of frequencies from an internal electronic cross-over), the output powers of both amplifiers are added to give a total rating. I.e. l.f. channel = 80W, h.f. channel = 70W, thus 130W total. This is misleading as the output channels never work simultaneously. The maximum output is still 80W only. [/QUOTE]
