JBL Professional has been an innovator in the field of studio monitor and loudspeaker design for decades. Since its release in 1995, the company's EON series has become one of the most popular powered sound reinforcement speaker lines in the world, with more than 300,000 systems sold.


The original EON15P, a biamplified, powered speaker system, featured a 15-inch speaker driven by a 130 W amp and a high-frequency horn driven by a 60 W amp in a lightweight polycarbonate enclosure. JBL has now released the upgraded version of this highly successful speaker, the EON15 G2 ($849).

The new EON improves on the input section by adding two balanced 1/4-inch TRS inputs with rotary trim pots to the existing mic/line switchable XLR input. There is a line level XLR output jack that is switchable between Mix (a mix of all three inputs) and Loop (only input one). A two-band equalizer section, providing 15 dB of boost or cut at 120 Hz and 5 kHz, is also included.

JBL has more than doubled the old power rating, bringing it to 300 W for the low-frequency driver and 100 W for the high-frequency driver. The new system comes in a compact, easy-to-carry package made of durable copolymer material. It weighs in at a lean 46 pounds - actually one pound lighter than the older model.

In use

The configuration of these speakers makes them exceptionally versatile. I used them on several jobs in a variety of capacities.

As keyboard monitors they were great. I was able to mix the keyboards in the EON15 G2 and send a single output to the main board. They sounded very full and the EQ provided ample control over the tone.

As vocal monitors they performed well, and they had no trouble providing enough volume to cover a particularly loud stage volume. The in-line graphic EQ came in handy for combating feedback problems.

I also used them successfully for front-of-house at a live band event catering to 300 attendees. The EONs provided plenty of power, and setup and breakdown was a breeze. In this case, difficult room acoustics made use of additional equalization a must.

I was especially impressed by the method JBL has devised for cooling the amplifiers. The cooling fins are located in the speaker ports so that the speaker itself pushes air across them. The harder you drive the system, the more you cool the amp. This eliminates the need for any cooling fans and increases power efficiency.


Having the speaker and the power amp all in one unit is a valuable feature. Combine that with an easy-to-understand user interface, lightweight package, plenty of power and versatility of use and you've got a system that is sure to be every bit as popular as its predecessor.
