pragmas: signal processing at speaker level is a WHOLE different animal than at line level. Heat is the lowest issue compared to the rest of the losses and lack of phase control. Have you seen a proper passive crossover, how much copper is involved in air core inductors etc? Should I post a picture of a good 3 way passive crossover so you can see?
It is NOT a disadvantage for seperate amp for each driver: active means its possible to provide the right power for each driver for matched dynamics acoss all the drivers. With seperate amps, a big peak in the bass does not raise distortion on the tweeter or midrange as it does with one amp. The cost of a big power supply and transformer for one big amp can be much more difficult and expensive to execute than two or three smaller amps.
Of course the manufacturer needs to do a good job with active- this is true of everything. It is true that active can be done cheap- especially using little Class D amp modules available everywhere now (95% of which sound awful).
IN the case I am very familiar with , ATC, the electronics are all analogue. ATC avoids digital for that changes too much too often and better to chose your own converters.
Whether analogue or digital designs, that has nothing to do with active vs passive.
