JBL has raised the bar significantly with the latest incarnation of their famous EON series of active powered PA speakers.

The new generation JBL EON 518S 18” Self-Powered Subwoofer boasts 500 watts of chest-kicking, floor-thumping bass and is the perfect compliment to the entire JBL EON line of professional, self-powered PA speakers.

Employing an 18” Differential Drive woofer, the EON 518S delivers a frequency range of 36Hz-130 Hz with a maximum SPL rating of 129 dB. Beneath the sturdy, rugged, DuraFlex compact enclosure is a built-in Crown Class-D power amp, known for it’s high power output but surprisingly lightweight. The entire subwoofer weighs in at only 65 lbs, a departure from Subwoofers of the past that were inherently bulky, awkward and just plain heavy to carry.

A built-in crossover circuit enables precise distribution of your audio signal to the proper speakers when hooked up to the EON 518S via the stereo loop-thru connector and results in a focused yet widely dispersed low-end signal that can fill the room with ample amounts of low-end signal. Well-lit signal indication LEDs let you know when the power is on as well as when you’re approaching system overload

Connections include a balanced XLR input,1/4” TS phone-jack along with balanced XLR satellite outputs. A built-in limiter circuit protects the EON 518S from overload. There’s a switchable hi-pass filter on the loop-thru outputs.

While the EON 518S was engineered to be a lightweight solution, its build quality is still quite substantial. Constructed of 18 mm plywood, it features a full-screen-backed steel grille and rests inside a copolymer bezel for protection.

A handy built-in 36 mm pole mount socket makes it easy to add an EON satellite to the system, making the JBL EON 518S Self-Powered Subwoofer a compact yet powerful low-end signal solution for your EON PA System. Perfect for musicians, DJs, public speakers, house of worship or anywhere that excellent, powerful sound is needed.

Comments about JBL EON518S 18" Powered Subwoofer:

I bought the 518's to go with a pair of EON 515's to replace an older passive system. Their best attribute is the convenience of the integrated amps and their portability. They are ridiculously light, but also pack a pretty good thump.

I ordered the 515's and a pair of the 518S subs, but they arrived a day apart. When I got the 515's first, I tried them out by themselves and initially, I was really concerned about the output. They sounded really nice at low volumes, but if you boost the low frequencies and turn them up, they peak fairly easily. Bass eats up that 350 watts pretty fast.

Once I got the subs and split the signal with the built-in high-pass filter, it was a different story. I ended up getting really nice and unexpected clarity and tone. Vocals and guitar were reproduced nicely - and at significant volume. This would not have been the case without the use of these subs.

Based on my applications, the 518's produced all of the bottom end I needed, and had plenty to spare. It produced really thick and clean-sounding kick drum and bass, and even enhanced guitar and vocals.

I would have liked to have seen a more detailed user manual. It's very basic. The 518's have a polarity switch, but the manual doesn't say much about it other than, "if the bass response isn't what you like, try flipping the switch" (basically). Doesn't explain what the polarity function is, or what flipping the switch does.

Overall, I'm very pleased with these subs. They are a vital companion to the 515's.
