I have to agree with Tom_Nice. I purchased sub cables from Serguei at Stealth Audio and they were significantly better than the monster cables with a local audio store recommended. They were approximately the same price as the Monster and the sound was much tighter and quicker. They sound like different subs. I have two Atlantic Technology 350's (12 inch, 200 watts) I do not believe you can get better cables for the price or even for several times the price.
