Lovely speakers from sonus faber with excellent sound quality even when used on tall stands, they produce a big, big sound when driven by a high quality amplifier and they are rated up to 200 watts rms. They can fill a large room with wonderful sound when driven by a gutsy amplifier. Any questions please contact me through eBay messages.
