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.
