[QUOTE="vasyachkin, post: 52360, member: 544250"] about this underpowering stuff - here is the WHY part so you can judge for yourself. if you have a system that is at least 2-way its tweeter will blow as soon as you drive the amp into distortion (clipping). this happens because distortion in itself is high frequcy signal which goes straight to the tweeter and fries it in seconds. you can fry a 100 watt tweeter on a 20 watt amp if you drive this amp into distortion. on the other hand if you have a 200 watt amp and play it at 100 watts it will not be distorting yet, and the tweeter will survive the 100 watts its rated for, while on a 20 watt amp the tweeter would be blown on just 25 watts or so (the extra 5 watts being distortion killing the tweeter). on the other hand, if were talking a subwoofer, or otherwise a sytem that is only one-way, with driver connected directly to amp - there is no danger from extra distortion (no tweeter to kill) and underpowered amp will be just as safe as one of proper size. this is one reason why recording studio monitors often use dedicated amplifiers JUST FOR THE TWEETER because that allows to disconnect the tweeter from the amp powering the woofer, so that when woofer amp distorts the tweeter does not see its distortion and does not die.
