Lets face it most people on here talk out of their ***. The T2 of course should not be expected to retain much SQ as it is a SPL sub. Now the T1 on the other hand actually sounds great. I would not Call it an SQ sub by any means. But I would not call a W7 an SQ sub either...also trigger fosgate isnt well known for sq that i know of from what i hear from you guys
