JBL Everest DD67000 vs. Avantgarde Duo Mezzo

Thanks for your opinions, please keep them coming.

ptss: JBL DD67000 were extremely dynamic, open, live sounding, effortless...than Revel Salon 2. Salon 2 had better holographic imaging and smother sound than JBL DD67000 but compared to JBL DD67000, Salon 2 sounded slow, boxy (before that I never understood what boxy of a box loudspeakers meant), compressed and closed in.

However, I'd have said the same negative things about any conventional box based dynamic loudspeaker after listening to JBL DD67000, thus, not sure if those shortcomings are fault of Salon 2 or the whole design category.

I am not sure about Avantgarde Duo Mezzo’s sensitivity comparison with JBL DD67000.

Avantgardes are semi-active loudspeakers. In case of Avantgarde Duo Mezzo (107 dB), there is a 500 watts Class AB amplifier for 12" woofers; external amplifier is only powering horns till 170 Hz. Whereas, JBL DD67000 (96 dB) is a pure passive loudspeaker. I suspect it’s sensitivity will also go really high if there was a built-in 500 watts amplifier for 15" woofers. And some people are doing active bi-amping with low power amplifier for the bi-radial horns and massive amplifier for woofers.

hornguys (Jim), would you please share with us what loudspeakers are you using these days?

It seems that  Avantgarde Duo Mezzo will finally put me on SET amplifiers train while DD67000 is best served with power!
