Hi
I read a couple of articles regarding putting a high pass filter at around 80hz to relieve the main speakers of frequencies and diverting them to a subwoofer. It’s supposed to be better for the main speakers. One article also suggested putting a low pass 80hz filter to the subwoofer even though it might have a built in filter.
I would like to try this out by putting the filters between my tube preamp and tube power amp. Try as I may I could not find any information on the sizes of the capacitors or details of how to calculate them and any associated components required.
I was just looking to try it out as it seems a logical approach, but no information seems to be available.
Like all these things I suspect it’s a lot more difficult than just soldering a cap in place.
Many thanks
