Just wondering about speaker cables

What you're describing is a fairly conventional set-up called shotgun, but with a significant variant.  Classic shotgun is two identical cables terminated at both ends with single set of spades or bananas to attach to amp and speaker.  Hence the name: double-barreled.

In a biwire situation, you could certainly have one type of cable on the speaker's tweeter connection, and another on its woofer.

You suggest, in a sense, combining these two set-ups.  As others have suggested, if could just as easily (or more easily) lead to messing up the sound as enhancing it.  Given that there are so many variables, only a trial would tell.

Or just find one cable that sounds good to you on all levels.  Lord knows there are enough out there to choose from, and it saves you from all the mixing/matching, trial and error, and potential added expense of going the other route.  Then again, whatever blows your skirt...

twice the cable twice the fun twice the music twice the bass... do it!!!

let us know how it goes!!!!!

just kidding

This was the first cable thing I ever tried, shotgun two runs of the same wire. Flash forward 20 years, Ted Denney Jr makes his element Copper Tungsten Silver speaker cables, three completely individual cables combined into one. I don't recommend it if you have to buy a set of cables, but you have them just laying around then the cost is zero and the benefit is not zero so go for it.

Very bad idea could never work.good luck.
