Advice on components/coxials?

Not sure exactly what the relation from pounds to USD,s but I will try and help. I personally recommend going with a pair of Polk DB series Component speakers. I have these guys and I love them. The RMS rating is about 100 watts and they are 4 ohm's speakers. You could go with the components in the front and if you wanted you could do coxials in the back (personally I would just go with 1 set of components in the front and leave out the back speakers and amp the tweeters as well that way it will still be at 4 ohm's and be ok). I think that thesse will do you great justice and you will love them.
