Witch receiver for a Canton Plus C woofer (passive)

I have a got :

- Canton Subwoofer (Passiev) Plus C

- Canton Satellite speaker AV 500


Its a German set so the links are in German, but maybe it helps to get an idea...

What sort of receiver do i need

And can i get some brands and types

I got a budget around 180 dollars, so it has to be a second hand.


Cheers,
