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.
