Active speakers have always had a number of advnatages IMO.
The most basic is that instead of having to deal with 2 components you get to deal with 1. The producer and consumer dont need to worry did I match the speaker with a amp that can deal with its impedence curve and also match its tonal characteristics. It allows the deisgner to design an optimal solution that delivers what they want in an easy way that creates less opportunities to mess up their design. Think of this as the mac--mini versus build your own PC. Its simpler from an end user prospective and the package/solution is optimized. No tinkering required....
The 2nd is far more complex. Passive speaker crossovers have always had limitations in what you could execute at a reasonable cost both sonically and financially. Active crossovers and even more specifically digital active crossovers like the ones mark uses in his designs give the designer a ton of flexibility in being able to impliment crossovers topologies that would not be possible in passive designs. Mark has told me numerous times that using his DSP crossovers is how he can get a compression driver so integrate so well and sound so good. This level of performance would not be possible with a passive design.
To me this is very desirable and I have always enjoyed the sound of meridians speakers which do all this and one more peice that mark has not yet done. They accept digital input eliminating a D/A in the pre-amp and an A to D in the speakers crossover.
Why the concept of active speakers has never become to mainstream is beyond me. As an engineer it makes perfect sense. eliminating that extra A/D step could result in even cleaner sound. Then all you need to run to each speaker is power and a toslink or Cat5 cable.....
hope this helps...
