Have for sale a HSU VTF3-MK2 subwoofer for sale.
It has a bad amp.
I called HSU and they can repair it for $140 + shipping.
Alternatively - you can get one of their new amp modules for $250.
Considering the above, you can have a fantastic subwoofer for $265 to $375.
HSU is one of the most respected names on subwoofers.
