What is the role of the resistor in the bass speaker? Will the cutoff frequency be affected when the resistor is cancelled?
answer 2.
0.3mh and 33uf capacitor 3ohm speaker = 1600hz
What is the cutoff frequency for 6.5ohm using the same materials?
interesting
what’s interesting ?
is there anyone who can help ?
The resistor is part of the low pass filter. Yes, the cutoff frequency will be affected if it was removed. If you replace the 3ohm resistor with a 6.5ohm resistor, the cutoff frequency is lowered to ~741hz.

You got multiple segments in one circuit there.
What I find interesting is that this secition:
Is a “reversed” LC-Filter. Normally, the load would be in parallel with the capacitor, not with the inductor.
This here is an LC-Filter with a resistor in series with the Capacitor (like @reikoshea mentioned).
I THINK this is probably a compression tweeter. It’s pretty common to throw a resistor in parallel to drop the power of compression drivers because some will run as much as 6db and 9db hotter than most woofers.
Just a guess though.
