The JBL IRX115S powered subwoofer, the newest model in the IRX Series of versatile, cost-conscious portable P.A.s, extends the low-frequency response of IRX systems down to a room-shaking 35 Hz.

The 15" IRX115S draws from JBL's top professional technologies to deliver superior sound without the guesswork, thanks to custom driver and amplifier designs; tuned, ported enclosure; and built-in crossover and polarity settings. It all adds up to an impressive 128 dB of deep, powerful bass, in a rugged, ultralight cabinet weighing less than 66 pounds.

The IRX Series offers legendary JBL fidelity, power and ease of use at a fraction of the price and size of comparable systems. The 8-inch IRX108BT and the 12-inch IRX112BT are fully loaded with features that make it easy to dial in incredible sound in an instant-from real-world EQ presets and dbx DriveRack automatic feedback suppression to Bluetooth streaming and one-touch ducking.

Budget-conscious musicians, DJs, presenters and fitness instructors can count on versatile, full-featured JBL IRX Series portable P.A.s to deliver stunning sound, no matter their experience level.


The IRX115S leverages more than 70 years of JBL speaker innovation to deliver superior frequency response, sound pressure levels and sheer power. Inside, a powerful 15" woofer with 3" voicecoil delivers low-frequency coverage down to 35 Hz; a 1,300W high-efficiency amp helps protect the woofer and driver while ensuring top-level acoustic performance. Selectable 80 Hz, 100 Hz and 120 Hz crossover points smooth out system response, especially when used with IRX Series loudspeakers; a tuned port reduces woofer noise.


The tough, lightweight IRX115S is engineered to outperform larger boxes in a compact form factor weighing less than 66 pounds. Its durable MDF enclosure features a tight-gauge, reinforced honeycomb bevel pattern that offers rugged protection without compromising acoustic performance. Transport is easy, thanks to thoughtfully designed ergonomic handles. And it's all verified by JBL's legendary 100-hour stress test.
