Consider getting two subs instead of one. Vanns frequently has 10" Klipsch subs in their clearance section for around $200. A pair of them would work.
I Love Vanns !!! I got my entire system from them and saved 70% what I would have paid through a local retailer (You know who you are BB). I added a center speaker to the mix that helped out the older folks not hearing the words too good due to bad hearing, I bought the JBL CSC56 300W 5" 2-Way Center Channel Speaker. It has fixed all my problems. Roughly $325.00 but, way worth it ! You can hear stuff that is usually said under the actors breath, which is a plus for me, since I could never hear that before due to the background music taking over, the center will fix that !
I have 2 subs and never tried it with one so, I have to agree with KidHorn on this one !
