Hi, I just read this line. Cost was a BIG factor for me, as is music. I did not want a HT sub. I wanted a music sub. I got the 10" Titanic to go with my M3ti's. If you search long and hard you can check a number of reviews and specs. The 10", due to design, is cleaner and plays flat lower than the 12". And it is a lot smaller. I am blown away by the 10". Yes, it stands up to any sub smaller than a coffee table and it is small enough to "hide". The only sub even close is the Hsu. Now, I have not tried the Axiom subs. There is nowhere near to listen to them. I have not read sparkling reviews as I did for the Titanic Vance.
