tweeter resistor = tweeter level control

Posted by DrChaos on November 9, 2020 at 16:42:16:
"Also, comparing a tweeter level control turned to max with a speaker designed to reproduce the complete range of high frequencies is meaningless."

It's not. How else do you think the tweeter controls on other speakers work?

+ = no resistor
0 = moderate resistor
- = more resisting resistor

Come on---at audio frequencies these resistors are purely ohmic devices with virtually no nonlinearity, it is nothing but a level control.

After all the tweeters themselves have that very same ohmic resistance physics because they aren't made out of superconductor!

Adapting crossover and balance to match sensitivity of drivers with appropriately sized resistors is standard practice and there isn't any magical effect on "purity" or some other nonsense. It's just a resistor and changes tweeter level and that's it.

Accounting the reflectivity of the room and balancing the sound power for it is what is important.
