The Sony developed a tear along with other cosmetic defects, so I returned it. (They gave me $20 more than what I paid!) I went down the street and bought an Infinity Reference 1020W 10" and put it in last years model Q-Logic sealed box (that I had laying around) with a 1" layer of poly for depth. I'll edit this with my observances of the new sub later.
(All Infinty sound system now! Well..except for the sub amp.

)
UPDATE: All I can say is damn.

This is one awesome SQ sub. I like SPL too, but I don't need bone rattling all the time. This sub hits all the notes, WAY better quality than that Sony I had.
