It's a 2039 CS with Samson 700W (350W x 2) amp. If you found that you needed more bass you could pick up a second one and use the other channel in the amp. It's in great condition and sounds great. If you are interested I will take a pic for you. I need to get $400 for it. It cost me $1600...
Hey Mike: I have a SVS 2039 CS with Samson 700W amp that I am selling. It's a great sub. I know it's a little bigger than you wanted ( 8 inches ) but I thought I would let you know anyway. Let me know if you are interested. Drew
