Zenclosures More Blindspot?

Oh and as for the other question, is it a well built box. While I know little to nothing about box construction I can tell you that it is very sturdy, sealed well, and the carpet used is probably one of the best matches I've seen for a non custom box. It helps the subs produce great sound. So my answer is yes, but like I said I don't really know much about what makes a box better than another (as far as sound goes).
