Summary: Versatile and great-sounding, the Eon One is a perfect sound reinforcement solution for a solo artist or up to a small combo.
Pros: As you’d expect from JBL, the Eon One has a fantastic and balanced sound. The array disperses the signal pretty wide and will fill a space quite nicely. The 10″ subwoofer rounds out the bottom end without being boomy or thumpy (though you can definitely get there with EQ). There’s also no extra bag to hold the risers and array. They all fit in a compartment at the rear of the unit.
Cons: This is a nit, but it seems as if there’s a difference in power using an instrument cable versus an XLR. When I plugged my guitar straight into the input, I had to crank the volume to balance it with my vocal. Suspecting that power-handling was different, I ran my guitar into a passive DI and lo and behold, there was a definite power jump. But like I said, this is a nit. Besides, from past experience with different PA systems, it’s always a good idea to go into a DI with my instrument outs.

Tone Bone Score: 5
Based on the sound quality alone, I give this 5. But I could also give it a 5 for its smart design. JBL really did have the solo musician in mind when they built the Eon One.
Street Price: $999
I have to admit that it took me a while to get used to the sound projection of this unit. My old SA220, while it dispersed sound pretty good, was definitely much more directional. With the Eon One, sound dispersal is wide and it doesn’t seem like it’s loud enough. But that’s the point of a speaker array like the Eon One. It’s actually a lot louder than you think. The sound is dispersed so well that it fills the space.
For example, while I was setting up for my gig this morning – a teen retreat for my church – I connected my phone to the Bluetooth on the Eon One and played some music. At first, I didn’t think it was very loud and I cranked it. But then one of the retreat leaders arrived and we started having a conversation. It was difficult for us to hear each other which forced me to turn it down. But even at a lower volume, the awesome thing was that the room was totally filled. No matter where I was in the room, the volume was level. Damn! I love that thing!
Fit and Finish
At 40 lbs., it’s no lightweight. But the way the unit is designed, it’s actually incredibly easy to lug. I lugged it up two flights of stairs and it was like carrying a large suitcase.
It’s also durable. I tipped it over with my handcart by accident onto the blacktop in the parking lot of the retreat center. I was so nervous that I might have damaged something, but I plugged it in and it worked like a charm! Though I’m bummed because I hadn’t even used it yet and I scratched it. Crap! The body is made of high-velocity plastic, so it’s pretty tough.
How It Sounds
As I mentioned above, the sound dispersal of the Eon One is incredible. It’s actually a little unsettling because you just don’t need to be that loud to fill a space. I was so used to operating with a much louder volume with other PAs that I just didn’t think I was loud enough with the Eon One. But it’s deceptively loud because of the dispersal. You just don’t realize it until you’re in the middle of the space and you can’t hear the person next to you. 🙂 That’s a good thing!
But as far as sound quality is concerned, it’s like playing through a HiFi stereo. The sound is crisp and clean. There’s no signal noise whatsoever.
As the retreat participants were arriving at the venue yesterday, I was playing music through the Bluetooth connection. It was like listening to my surround sound system! The music sounded so good and I have to say that that subwoofer makes all the difference in the world, rounding out the bottom end and providing a richness I hadn’t experience in my old SA220.
My close friend Catherine who was a retreat leader walked up to me when she arrived and remarked, “The sound system is amazing! Did the center upgrade their system?” I laughed and said, “It’s like a HiFi, right?” She agreed. Then I pointed in the direction of the Eon One and told her all that was coming from that slim, little unit. We both cracked up at how great it sounded, and then she said, “I can’t wait until you start playing. You’re gonna sound awesome!”
I was so pleased with how I sounded yesterday. With the subwoofer on the Eon One, there was a warmth in my sound that I had never experienced with my SA200. And don’t get me wrong, the SA220 is actually a great PA, but the Eon One is on a totally different level as far as sound quality is concerned. I’m probably going to donate the SA220 to my church so they can use it for events.
Every year, I host a large party at my house where I barbecue a whole pig. It has been a family tradition since I was a little boy that I’m carrying on to this day. My son, who is learning the tradition from me, remarked that the Eon One would be great as the sound system for our pig roast when he heard it. And because its footprint isn’t nearly as much as the SA220, I could position it in the corner of my patio to keep it out of the way.
Ease of Use
I thought my SA220 was easy to set up and use. Though there are more pieces than the SA220, none of the pieces of the Eon One are bulky, and the risers and array just slide into place like Legos. And the fact that they’re right there in the back of the unit makes it so much more easy to set up.
I read some complaints from people that it’s difficult to take the unit apart as the pieces are snugly put together. People have used silicon jelly to help with that. I guess they just want to pull the risers out straight. But it’s really not that big a deal. You just use a gentle rocking motion while pulling out and the risers come out easily. For me, I’d rather not apply a lubricant on the equipment as that will collect dust.
As far as the controls are concerned. You have Bass, Treble, Volume, and Reverb Level knobs. Very straight-forward. I was concerned that there wasn’t a Midrange knob, but it’s easy to dial in a balanced tone with just the Bass and Treble.
Best Bang for the Buck
Are there better-sounding systems? Absolutely. The Bose L1 Model 2 is scary good. And the HK Audio SoundCaddy beats the shit out of the Bose in my opinion. But both cost $2500 and $2800 respectively, which put them out of my price range. And while the Eon One may not be at the level of those two systems, it’s close. Damn close. And frankly, the only person who can tell the difference is me. My audience doesn’t care as long as I present them with a pleasing sound. And that’s why we have EQ. 🙂
So at a fraction of the cost of the high-end models, I’m getting great sound that can be used for the venues I play. It’s hard to argue the value proposition of the Eon One.
Good review. I bought two of these to use basically with a Hauptwerk digital pipeorgan software. So we’re not playing much rock and roll with this. However, I want to use it in a venue where there’s no electrical power.
I’ve been looking at the anchor Powerhouse portable power sources. But I have no idea how much power I need for these speakers, using either one or possibly two of them. Do you have any idea what kind of battery power source I would need for one or even two JBL Eon ones?? I have no idea. Thanks so much for your good review and any help you can give me.
