I've been out of the Home theater loop for a while, and upon my return, noticed that a fair majority of those here cannot say enough about the SVS subwoofer. Any of you SVS users intimately familiar with the M&K MX-350THX also? and would you, could you, make a comparison? M&K users have any opinions? Is the thing a glorified boom box, or is it tight and accurate? Deep is one thing, accurate is another. So what say you.
