FS: 10" sub with box

i dont know if anyone would be interested in this. I got a sub a while back, and made a box for it (MDF) well its just been laying around in my room (attached to my system) i guess i should sell it. I think around 100 bucks would seem reasonable.

It is a sealed and carpeted.

price is negotiable.

What brand is the sub? Any specs on it? I’m considering it, but 100 bucks sounds a bit steep, considering someone else was selling a pair for that much.
