Watch Wharfedale 225 demo. 25-120 watt max. 8 ohms, 87db. Woofers are made of woven Kevlar and beautiful rosewood cabinets and I have to say sound amazing. Running them with a 200 watt Acurus amp, Hafler pre amp and using a sony cdp-302 cd player. I am very happy with these speakers. Upgraded from the Kef C2s.
