Crossover resistors

[DanFXR]

After a speaker cabinet went out on me I took it apart and tested each
speaker , 3inch,4inch and a 15 inch.
All seemed fine.
I replaced the 2 caps (1.5 and a 6) and the resistors (5w 2.2 Ohm) .These
are the same values as the old ones.
Almost no sound was making its way to to the 3 or 4 inch. speakers. I
removed the resistors and it sounds as good as it used to.
My question is what funtion does the resistor play?
Does it protect the speakers from overload?
Thanks

Presumably they contribute to the crossover's frequency domain
performance -- e.g. its Q.

Works with the inductor and capacitor to determine what frequencies are
passed to the drivers. What frequencies that are blocked from the drivers
end up as heat dissipated by the inductor and resistor.

Resistors mainly control the amplitude to adjust drivers outputs. Very few
drivers have the same sensitivity. The resistors also can increase power
handling, have effects on crossover frequency and phase, and can change
damping. Off axis response will change and response will change. Somehow your
not going to get the same response by bypassing the resistors. Changibg
capacitor types will also change things.
