One of the best-selling series of professional speakers by JBL is the EON series. Released back in the 90s, this series has been a favorite for professional engineers and recording artists. The JBL EON718S Self-Powered Subwoofer is the largest in the subseries at 18 inches. 

Part of the EON700 family, this active subwoofer has a simple box-shaped design with built-in ergonomic handles on the sides to help lift it. It’s large but still portable, so it can even be used on the road. 

This is better suited for live sound as it packs in quite a high volume. That said, it’s super versatile and can be used in any venue where you need volume with a powerful punch of bass. 


All JBL EON700 series products, including this sub, utilize advanced digital signal processing (DSP) that improves the live sound. It has a peak power requirement of 1,500 W, so you can imagine just how powerful this 18-inch subwoofer is. 

It also has a built-in two-channel digital mixer, so it can accommodate two mixers or other inputs. 

As it’s designed for use in live venues, they have made it quite sturdy. Its housing is made of 15-ply birch enclosures that protect everything on the inside while also giving the sub a contemporary look. 

One of the standout features of this product, which also makes it an ideal choice for live sound, is that it has acoustic engineering. In other words, it’s designed to take into account the acoustics of the space when producing bass. That’s innovative but also super convenient for those who play in different venues. 

It can produce bass as low as 31 Hz with a max SPL of 131 dB. JBL says it has tested this sub and other speakers in the series for 100 hours straight to detect failure or loss of quality of sound. Fortunately, it’s reliable for those long performances, such as weekend nights at bars or festivals that go on for days. 

It also has a threaded pole mount at the bottom, so you can put it on a pole or even stack it.
