So if I have 100w per channel left has two speaker 50w per speaker if hook two speakers. Right channel same.
So if I bi-wire my towers it will give 50w to subs (low) then 50w to tweeters ( highs) the tower dose not have to split signals with circuitry any longer.
I personally notice difference not huge but better highs n mids. Worth it
kinda like jumping up your cartridge one notch on your TT.
