Oh, btw, not that this is really relevant, but I thought I'd pass it along anyway. When the DEQX guys were measuring my system, they plotted the frequency response of the drivers. The room wreaked havoc on the mid and low frequencies. That's where the DEQX helped.
But the beryllium tweeters were unbelievable. Their resonance frequency was close to 40,000 Hz. And the tweets were flat out to 20,000 Hz and started to gently roll off at around 30,000 Hz.
