Best speaker/system piano concerts

Aside from wanting a speaker that is good for this or that I have to say that I would be loath to find out that a speaker system I was interested in was peviously owned by someone who was into heavy metal music. Reason being that the music played by these bands has so much intentional distortion put into the signal by way of fuzz boxes and other electronica that instead of saying what kind of music they were good for if thinking of buying used the first thing I ask is what kind of music they were used to playing. If classical then it is usually safe to buy because classical is the least distorted music generally on carriers. I have had the misfortune to go to a friends house to listen to a pair of studio monitors that were previously used for rock use and had to tell him his woofers were gubbed due to high volume distortion and it cost him two new drivers.

Any kind of music including piano can damage a speaker if the speaker is abused in some way. I wouldn't blame that on rock.

I play electric guitar frequently, putting distortion from various tube amps through guitar speakers in open back cabinets...I also play cleanly through the same rigs...these things should last for several decades as others I've owned have. I also have some old KLH Model 20s from a compact system I bought in 1970 or something (my first great sounding stereo) and they still sound great (relegated to a garage system). So there.

Underpowering any speaker can ruin it.  Any amp that isn't up to snuff can ruin .....  Bottom line is that it's hard to buy a used speaker.  Plenty of folks do and are happy, but I've heard so many horror stories about used speaker buys.  I have sold 7 pairs in my life and all three ProAc's need all new driver surrounds or speakers.  I wanted to make sure that I wasn't going to screw anyone, but plenty of folks do and will.

I would only purchase if I knew the person or maybe if it was local and I could go listen first, but even then, I'd shy away.  That's just me adn I really that, but often times folks end up with inferior amps in order to get 'better' speakers and they ruin them.  I agree that it's not just distorted rock. 

Underpowering any speaker can ruin it.

FWIW dept: the result being a fried tweeter.
