This is an auction for a Hertz 400watt slim subwoofer. It has been used but looks like new. The picture showing the connections makes the connection plate look like it is scratched but this is purely the plastic protective film which you would remove when fitting. It really looks unused. The dimentions are 52cm wide x 32cm deep x 9cm high. It produces unbelievable bass for its size. Any questions let me know.
