I have the S10, which is more than enough in my current living room.
However, I'm building a new house which will have a much larger room.
So, I just got the S12 from Vann's.
I've long been a fan of Mirage speakers. These subs are terrific.
BTW, the S12 was $700, so the $499 is a great price (I paid $499 for my S10!)
