This House Believes:
1) an active crossover is, theoretically, technically superior to a passive one, producing less distortion.
Theoretically and demonstrably
John Duncan said:
2) improved accuracy is not necessarily audible (cf 16/44 vs 24/96).
True, but if that is a counter to 1) then it's a straw man. 24/96 is not audible as it only gives us frequencies which is proven that we cannot hear. Passive crossovers can introduce levels of distortion that are well within the realms of human hearing.
John Duncan said:
3) since very few speakers exist that are available in both passive and active versions, it is extremely difficult to make an objective comparison between just a crossover.
Yes to you and me unless you hunt one down that does exist.
John Duncan said:
4) many other variables exist in speaker manufacture.
Yes. But it does seem that this is a "biggee" and makes perfect sense if ultimate SQ is the intended aim.
John Duncan said:
5) for any given active speaker, there exists a passive speaker that sounds better than it.
6) for any given passive speaker, there exists an active speaker that sounds better than it.
They can't both be true. The answer is not realistically attainable.
John Duncan said:
7) active speakers have the potential to have their amplifiers built specifically to match drivers. However, whether all manufacturers do this is unclear.
True.
John Duncan said:
8) it is possible to find an amplifier that matches a passive speaker perfectly. It just takes longer.
True. You can get an amp that is the perfect match. So if you also have the same speaker with perfect matching amps on each driver with an active, rather than passive crossover, the active version will be a) cheaper, b) higher SQ
John Duncan said:
9) given two equivalent-sounding systems, the active one is probably cheaper than the passive one, since there are fewer boxes to manufacture.
True, but not only because of box count. Integrated amps must be over-engineered(more money) to suit a wide range of speaker loads, so the amps in an active design can be cheaper even if they are external
John Duncan said:
10) there are both active and passive systems which offer spectacular value.
True, but in the case of passive systems they exist only at the budget end of the market or on ebay if you compare to the value in actives. Whereas if you are willing to venture into pro-audio then there are bargains galore in the active case because of a combination of 9) and the fact that the profit margin in pro-audio is a lot lower.
John Duncan said:
11) there are both active and passive systems which are overpriced.
True
John Duncan said:
12) If we believe all the above to be true, one must conclude that none of: crossover, driver, cabinet, wiring, topology, whatever in isolation can define how good a speaker is.
True, so if you want best SQ possible you should follow best practice in each area. ergo use an active crossover.
John Duncan said:
and finally, just for kicks:
13) Every single hifi manufacturer on the planet - whether they be manufacturers of active or passive equipment - is trying to make as much money out of you, the consumer, as they possibly can. Anybody who tells you that they're not, but that everybody else is, is...mistaken.
Anybody in?
I would say "trying to make money out of you, the consumer". Some companies overcharge, some don't. Some companies products are overpriced, some aren't.
Also, your insistance that Max answer "Which one" is unfair. See 5,6.
