until i get lsi setup

[scottyboy76]

until i can afford nice polk setup i buy deals on cl. the latest involve some from an estate sale,(2) prism 500s,a sub and a strange little guy all from apl technology speakers. a now defunct atlanta co.
the sub is not powered and has four sets of binding posts, none marked except polarity.
also a little speaker marked sat1079. one small felt covered hole on one side along with what appear to be rubber feet, on the opposite side are the binding posts.sounds great, but by appearance looks more like a remote sending unit rather than speaker(possibly one of what was a set of surrounds?)
also included was a polk center that is now sitting in place of my cs2,it has no modelstickers or plates.
pics are not perfect but any help on how to hook up sub,what the sat speaker is,what model polk center would be greatly appreciated.
