Even if you've got attenuation set (by whatever means), you have to be careful with test tones. Music doesn't contain that much energy at high frequencies, so tweeters have quite low power handling capability. If you play a high frequency signal at full volume, then chances are that your tweeters will blow.
(This is also the reason that using *underpowered* amps is the easiest way to kill speakers - you turn it up trying to get the required volume and the amp clips. Clipped waveforms contain serious amounts of high frequencies). -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=72639 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
