Do Vandy subs benefit from better cables?

Hi,

I'm the proud owner of a pair of bouncing baby Vandersteen 2wq subwoofers. Love 'em, and love what they do for the system.

Currently, I'm using the stock speaker cable that came with the 2wq, between the amp and the subwoofer.

Would the 2wq benefit greatly from having upgraded speaker cables? I thought I read somewhere that because of the nature of the signal, it really wouldn't matter much.

And yet, everywhere else it seems that improved cables make a big difference.

Thanks,
