Hello,

Sorry if I sound like an idiot here. I get really confused when it comes to watts, ohms,

I just purchased a Panasonic SA-HE 100 per Consumer Reports advice. I needed to get a new receiver because the RCA theater in a box was a piece of crap (live and learn). I am trying to use its speakers with my new receiver. All the speakers work except for the sub. This new receiver only works with an active sub. Is this the same as a powered one? Can someone please dumb this way down for me and recommend a good sub for under $300 to work with the Panasonic?

Thanks!
