WARNING ....not an electronics expert.. not even an electronics amateur...
but I just built an electronic subwoofer crossover from a kit, I simply soldered and prayed a lot It has a volume gain pot but it has no cut-off frequency pot, it has a DPDT that switches from 50 or 70 hz. Is the default 50 or 70 hz setting based on the values of the resistors and capacitors ? Does the two IC thats built into the kit play a role in the cut-off frequency. My goal is to change these to 30 and 40 hz, as I can still localize the position of the sub on the 50 hz setting.
I know i need to post the schema, but as i have not taken a photo of the schema as of the moment. If the 50/70 hz cut-off is based on the IC then there is no need to post the schema as this would not be possible to change given my expertise.. thanks

Most likely, yes.

That sounds more like a problem with the slope, it may be too gradual and letting too much high frequency through.
Re: Re: electronic crossover modification
good so it can be modified
What if I daisy chain two Electronic crossover ? its an 18 db per octave crossover..will this now be an 36 db per octave crossover ?
is this good or bad ?

Hi here is the schematics...
thanks
