How about yg acoustics dual coherent the crossover coherent in both time and frequency domains?

You got me thinking about single driver vs. time aligned multi driver. What do you think about
Fujitsu Ten Eclipse TD712z loudspeaker
A single 4.7" driver with a glass-fiber cone is mounted in an egg-shaped enclosure of artificial marble,
Which would you choose?
What is the ideal number of drivers in a loudspeaker system?
a) two
b) three
c) four or more
d) none of the above
You have your answer? Good. Next question:
What is the best type of crossover in a loudspeaker system?
a) first order (6dB/octave)
b) second order (12dB)
c) third order (18dB)
d) fourth order (24dB) or higher
e) none of the above
Single drivers imo are a gimmicky mess with their over compression that happens are the breakup mode. they narrow up too early and become pinpoint directional for treble so very tapering and thus in room will sound dark and bright at the same time.
haven't heard that YG speaker but the ones I've heard have been pretty good sounding with good honesty and delivery of tonal balance.
Ideal number od driver depends on what implementation you wanna do.
Provided the drivers are chosen meticulously with parameters that makes marrying one to another easy, I'd say a 3 way is pretty much a great balance across board. Can help with sensitivity. But you gotta be good with your crossover slopes to mitigate transducer limits. first orders are not ideal imo. 2nd, 3rd and 4th have their uses depending on the drivers you're using and what kind of balance and control you wanna achieve
