Thoughts on Active/Passive Speakers? Looking for pros and cons.

Active crossovers are the BEST. Contrary to what hilde45 said, the opposite is true, gives you more amplifier options. Benefits - Almost total elimination of intermodulation distortion, which is what your ears are most sensitive too. No phase shift, extremely low THD, no delay unless you choose to add some. Very low resistance between voice coils and amplifier outputs, so more power goes directly to the drivers. I do not use anything but wire between the driver voice coils and amplifier outputs.
Passive crossover benefit - You may not blow your drivers if the amplifier has a hard failure. However, with an active and nothing between the voice coils and amplifier outputs, I have only blown one (1) midrange and (1) tweeter in 41 years! (Tri-amped) It is not a guarantee that you will blow a driver without caps and inductors in line with the outputs of the amplifiers. It is a guarantee that the sound will be muddy and not as clear as an active crossover. Wait for others to respond.

@fiesta75 I only assumed that if the amp was built into the speaker, one couldn't try different preamps & amps to get different synergies with the speaker. Is that mistaken? Please help me understand. I don't want to mislead.

Sorry, guess I'm the one that jumped to a conclusion. I was not even thinking about amps internal to the speakers.

In all of my experience active speakers were always suggested to be better than passive speakers.

The main (only?) drawbacks were always said to be greater expense and greater complexity of setup.

Having said that the only active setup I was quite familiar with was an Alpine car system.

Did it sound good?

Yes it did, with an exceptionally dynamic and fluid sound!

Actives are built to matched amps. The only thing they limit it is your ability to blow dough.
