This sub is less than 1-year old (I am the original owner)and is in excellent condition. I am asking $500.00+shipping. If you happen to live in the Denver area or somewhere near I will deliver to you. You can also come see and demo the sub for yourself at my house if you are in the area. I am moving out of my house and most likely into an apartment at the end of April. This sub would be WAY to much for apartment living and I would probly get kicked out if I attempted to use it there.
