Any HT members out there have any experiance with these drivers or can someone point me to some car audio site that has reviews on the W7 line drivers?
Yes, I have built enclosures for all versions of the W7 subwoofers, both ported and sealed. They are excellent. They are also pricey. If you are looking for car audio reviews, go to this site and search under the 'Subwoofers and Enclosures' section of their forum:
