Up for sale are three subwoofer cables of different lengths. 
Excellent condition, with only a few marks on the jackets and connectors from normal use.

Note from my experience: any of these will be better than the popular Blue Jeans CL-1. Even though it's a good cable for general purposes, it has a weak low end.
