Well I keep doing some research on these new JBL EONs...
Aside from a few "oh my god, these are the best speakers EVARRR" and a few "uhm, not that great sounding" reviews, there's nothing online about them. In fact, they're new enough that the REQUIRED Bluetooth app to control the EQ on these things isn't even available despite them being released last summer. So there's no way to control the EQ on these.
So I'm staying away from the JBL EON612.
