Hi Thanks for reading I have a pair of 2-way b&w dm110 speakers, and a m&k active subwoofer
The amp I am using with the b&w is a topping pa5 II
I want to create a 2.1 system and make the b&w speakers reproduce everything over 200hz, and the subwoofer reproduce everything under 200hz
I’m thinking of removing the crossover from the b&w, and replacing it with a 100uf capacitor to act as a high pass filter. I’ll probably have to play around with the value of the 100uf cap to make it integrate well with the subwoofer
Q: Are big 100uf caps safe to use with amps on a long term basis, and would there be any resonance problems you can think of

Not likely to be a problem in series with the speaker.
The simple capacitor filter might get caught up on the impedance peak at Fs. If it does, it might be OK if it blends into the room, but it's not as though you have much choice with it.. so if necessary you could use a more elaborate filter or you could move it to before the amp.

Thanks ! What happens to the bass ? If the amplifier is sending bass to the speaker, but then the capacitor is blocking the bass from entering the speaker, then the bass has no where to go
Maybe have a look at this document, some of which could be useful to you: https://meniscus.lightningbasehoste...he-Kairos-and-Continuum-Three-Way-Writeup.pdf
Maybe I'm not clear on the project but isn't 200Hz a little high to cross a pair of speakers to a sub? Also, don't understand why you would remove the B&W crossover. Don't you still need it for the mid-tweeter transition?
The bass is just a changing voltage at a low frequency. The capacitor just impedes the flow of the low frequency voltage with no loss in the normal sense. Higher frequencies it passes more easily.
Its like turning a light switch off on the wall. Where does the electric go now?
Answer is that its not gone anywhere, its still there to be used when needed. Or replace a 100 watt bulb with a 60 watt. What happens to the electric 'left over'?
Or where do all the negative half cycles go in a bridge rectifier 😉 Answers on a postcard for that one.
