First time poster but have visited the site on many occasions. Right well my problem is this!!! I've been using a a300 Cambridge audio amp to power a pair of wharfedale 10.2 the amp being 50w pc and the speakers being 100w. I haven't noticed any clipping but did notice distortion when turned it up loud. I never new under power was worse than overpowered. So whenevrr it would distort I would, by ear turn it down until I couldn't hear it. The amp doesn't give a db. reading so I dont know how loud I pushed it but probably over halfway afew times though. Maybe 3/4 when I was try to annoy the neighbours. What are the chances ive damaged my speakers. There about 5 months old and haven't had much use if that even matters.
