My friend who lives in Denver has one and the PB10 is a nice sub for the money. Try to get it down to $200 and your good.

Ya, I would be leery also if someone would not let me listen to it before buying.

For $200 only if it's in good condition.
The pb10 is a capable sub but don't expect earth shattering bass in a room that large.

For $500 there is not much that can touch the quality of the pb10 unless you look for used.
