I run a small bia-amped sound rig. I could have bought Bass speakers and Mid/high two-ways. However, in order to make it flexible I have big and little two-ways. For small shows I can leave one set at home. I actively crossover well below the "bass speaker's passive crossover.
That crossover is real simple, consisting of a cap, res and coil. The high freqs go to a Piezo. How much is that crossover costing me? I was thinking of fitting a bypass switch.

If the cap, res, and coil are in series, and are in parallel with the driver (bridges the driver terminals), then it most probably is a zobel. If it's hooked up differently then it depends on how they're hooked up and the value of the inductor and resistor.
From what I read; the Zobel flattens the impeadance curve by dumping power ( still dont know how much). The reason is to make the crossover even.
However since I have already done the crossover work before the amp, I don't need it. Loosing power is bad at 300W. I would need heavyer amps and make too much heat. Even 2db is poor. I think in this case a crossover on/off switch will be a good thing.

Simple question made complicated. Sorry.
Cab with 15" and Piezo. How much power does the simple crossover waste?
