Thank you for the complements. I'll put them on my resume.
I believe I accused you of speculating in one of my posts,
so I guess I deserved this outburst of affection.

"In my experience, a 70 watt amp blew a 300 watt woofer."My reply:
Assuming the amplifier was honestly rated at 70wpc, it should
be able to reach roughly 140wpc at high levels of distortion.
Therefore, the woofer was unable to survive roughly 140wpc
due to overexcursion I assume, and most likely was overrated
at "300 Watts" ... or this rating only referred to the voice coil's ability to dissipate heat, and didn't account for overexcursion damage. Not very useful speaker or drivers power handling specs are common in audio.
JBL Pro drivers, for example, are rated for power handling using pink noise with a 6dB crest factor and the protection of a 40Hz. 12dB/octave high-pass filter. Someone I know damaged his JBL 2235 15" subwoofer driver from overexcusion because he he didn't understand how the JBL power handling number was calculated.
He used a very powerful amplifier and had no high-pass filter to protect his ported driver below the port tuning frequency.
