I'll have to definitely keep that in mind during the NH winters. Did not really have to worry about this when I lived in Texas. Very nice looking sub. It seems as though you almost have to rely on small companies or DIY group buys to get a quality piece of equipment any more. I have had good experiences with Image Dynamics, Adire Audio, and Elemental Designs. Unfortunately, I just do not have time for DIY so I will have to rely on someone else. Any suggestions?
