Our take on the JBL IRX115S Compact Powered 15" Portable Subwoofer

The JBL IRX115S is a powered 15-inch subwoofer built to add deep bass to IRX Series portable P.A. systems. JBL rates it at 128 dB with response down to 35 Hz, and it has selectable 80, 100 and 120 Hz crossovers plus polarity settings to match IRX tops. It weighs under 30 kg, so one person can move it, and it sits below the larger, heavier pro subs on portability while offering more low end than the 8- and 12-inch IRX tops alone. It suits DJs, bands, presenters and fitness instructors who want a compact, simple sub without a rack of outboard gear.

About the JBL IRX115S Compact Powered 15" Portable Subwoofer

The JBL IRX115S is a compact powered 15-inch subwoofer from the IRX Series of portable P.A. It extends the low-frequency response of IRX systems down to 35 Hz and reaches a maximum SPL of 128 dB.

It uses a custom driver and amplifier design, a tuned ported enclosure, and built-in crossover and polarity settings. The 15-inch woofer has a 3-inch voice coil. The ported enclosure increases output and reduces woofer noise.

The cabinet is made of road-tested MDF and weighs less than 30 kilograms. A reinforced grille protects the speaker without affecting acoustic performance. Ergonomic handles make it easy to carry, and a built-in pole mount allows more system configurations.

Questions and answers

Does the IRX115S work with non-JBL speakers?
Yes. The crossover points and polarity switch are tuned for IRX tops but work with other powered or passive speakers when you set the crossover to match.
How low does it go?
JBL rates response down to 35 Hz, which covers kick drum and bass guitar fundamentals. Larger 18-inch subs reach lower and play louder.
Can I use it without IRX tops?
Yes, it is a self-powered sub with its own amplifier and crossover. You feed it a full-range signal and send the crossed-over output to your tops.
Is one person enough to move it?
Yes. It weighs under 30 kg, so one person can lift and carry it, though the cabinet is bulky.
Does it have Bluetooth?
No. The IRX115S is a wired sub; Bluetooth streaming is on the IRX108BT and IRX112BT tops, not the sub.
What is in the box?
The subwoofer and its power cable. Speaker cables and tops are sold separately.
Where is the JBL IRX115S Compact Powered 15" Portable Subwoofer cheapest?
