Wow! The topic has seen more threads than a vintage Singer sewing machine.
You picked a good subject @donavabdear
The subject of active vs passive also involves manufacturing efficiencies and economics. It reminds me of the old days when, as a dealer, we were asked why separates cost more than a receiver. Putting aside the fact that there were usually better parts inside, there are also factors involved in producing 3 pieces instead of one.
- 3 chassis instead of 1
- 3 faceplates
- 3 on/off switches
- 3 shipping cartons
- 3 sets of packing materials
- 3 sets of service literature
- 3 sets of promotional materials
- 3 cartons shipped instead of 1
And, it goes on and on.
So, ALL things being equal (driver quality, amplifier, cabinet integrity, etc.), an active system would cost much less than separates. Or, theoritically, produce a better result at the same price point.
However, taking the cost, form factor, weight and other constrains out of the equation, the question becomes if a stellar amplifier coupled with superb raw drivers can overcome the added inefficiencies and distortions caused by exotic passive crossover components? And, that is the real question in my humble opinion.
