I don't know a lot about this to be honest but I bought it off ebay a while ago thinking I could just plug my PC into it. I was wrong.
I think you need an actual Home Cinema amplifier to use it properly.
I currently use the surround sound speakers with another system as they have great sound quality.
Although there are only 2 speakers in the pics, the sale is for 4 (I'm using 2).
So for sale is the subwoofer and 4 speakers with stands. The stand bases are solid steel and therefore very heavy.
Check out the pictures for all the connections and what not.
Currently just advertising this as collection only because of the weight of it.
Cash on collection.
Price - £50
