Default cheap subwoofer cable?

I just bought a used subwoofer.

Without starting a verbal war, is there a reasonable cost ($10) subwoofer cable somewhere?, or is the regular RCA cable work?

thanks,

gychang

Regular RCA cable is fine. Any cable will do as any capacitance issues only affect the high end, which will be well down in the subs stop-band.

Hi,
Don't you mean inductance? I don't really understand this so would appreciate an explanation to clear things up.
I thought that capacitance in cables limits the low frequencies.
I thought that inductance would roll off the high frequency response.
This is what I understand from building active filters but how is this translated into interconnects?

Thanks, and sorry for the dumb question,
Martin.

Dayton Audio & Knukonceptz stuff works well. I'm currently swapping out all my cables to Knukonceptz, they work great and don't look too bad either

No I mean capacitance.

No you have those mixed up.

If you imagine the cable is like a capacitor across the output of your source, it will load down the output rolling high frequencies off. Also, as output impedance also rises with frequency, the effect quickly gets worse.

sounds good, thanks for the tip. Someday I will have to try a double blind test....
