Over a year ago I traded in my 8" sub which was a few years old. I wanted more punch for my HT. I purchased 2 SS 10" subs for my home theater. These guys pack a punch! Everything comes alive with explosions and booms and shakes the 1st 2 levels of my house!! They work really well with my other 7 NHT speakers VT2 (front), M7 (center) recently purchased), VS2A (Rear), NHT Absolute (Surround).
