Sick of not finding anything other than "What hi-fi sound and visions" review on these Wharfedale speakers. Thinking of using 2 pairs of them to go front and surround with my diamond centre and SW150 sub. Can pick them up for £120 a pair where I live. Read a German magazine the other day that gave them 4/10 and got a fright!! Got a 20m2 room and don't know how large I need to go to fill it with decent sound and if indeed they would be enough or should I keep saving for something heftier. Amp is a Denon 1604. Yes, I am a bargain hunter!
