Well, this thread is kinda dead I guess - thought I'd reopen it with a couple of videos and some pictures of the sub - I didn't care too much for the RE subs, so I sold them and bought one of the S15L7s back - It's not as tight as the REs, but a whole heckuva lot louder - apparently the whole SPL vs. SQ is meaningless to me - as long as it's low I can't tell a whole heckuva lot of difference between them unfortunately. So, without further ado:
