I purchased 3 of these recently to use as stage monitors, and had high hopes after doing tons of research. Unfortunately, all 3 have lost their tweeter. I have never ever blown a tweeter in any speaker ever, so I'm shocked and incredibly disappointed that this has happened. After talking to local repair folks and other EON owners, this is the main problem all EON speakers face. I should have known better.
There are TONS of aftermarket diaphragm manufacturers ready to sell you replacements.
I primarily run sound for metal and punk shows, and play in several metal bands. The speakers can not keep up with the high range demands of this genre of music. Screamed vocals, heavy synthesizers, at high spl: the tweeters just can't do it. They're rated at 35w and, according to the spec sheet, receive 150w continuous (peaking at 300w)... So yeah.
On the other hand the woofers have not faltered at all, nor have the plate amplifiers. They can put out plenty of sound, but the tweeters just can't hang.
The good news is JBL made these speakers easily serviceable. The trash tweeters simply thread in and out after removing the grille and the screws holding the speaker case together.
The Bluetooth feature is complicated, ridiculous, and worthless. Don't bother.
If you play lower volume music at small venues, like generic acoustic singer/songwriter normie basic-b kind of stuff, these speakers are for you. Even if you're in a medium sized venue playing to about 100 people in your dad rock cover band, these speakers will do the job, but I would recommend a sub.
As far as sound quality, when they work, they sound good with recorded music, although they do sound boxy- like most speakers in plastic cabinets.
In short. If you want to buy these, buy these when they're discounted, stock up on tweeters, and don't use them for loud music, even as stage monitors.
