In Reply to: Re: A 40wpc amplifier is "underpowered" while 50wpc is not? posted by jslateiv on August 26, 2003 at 06:33:16:
There are pro standards for power handling detailed in a white paper at www.JBLpro.com:IEC standard 268-5
Pink Noise
6dB crest factor
12dB/octave high-pass filter at 40Hz.
12dB/octave low-pass filter at 5kHz.I have no idea what other speaker companies do.
Many tweeters in catalogs I have claim 50wpc or more power handling but never reveal what kind of protection (high-pass filter) is specified to make those claims ... which seem inflated to me.
Moot point though -- an average power output of 50 wpc would be TOO LOUD for you to stay in the room with most speakers.
