Never heard the JBLs, though at "only" 93 dB they'd not be an option for me and my 18 wpc amps. I'm sure that they are wonderful speakers.
Properly set up and amplified Duo Omegas do not have "slow" or "poorly integrated" bass, and at 108 dB sensitivity open up the possibility of low-power tube amps, which to my ears are the best of all worlds. To each his own.
