Get deep bass down to 35 Hz with the JBL IRX115S, a powered subwoofer with a space-saving design that puts out 1300 watts of serious, room-shaking low end.

The JBL IRX115S powered subwoofer, part of JBL's IRX series of versatile, cost-conscious portable PA speakers, extends the low-frequency response of IRX systems down to a room-shaking 35 Hz.

The 15" IRX115S draws from JBL's top professional touring 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 just 65.3 pounds.

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

Be Heard, Loud and Clear

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 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 IRX100 Series loudspeakers; a tuned port reduces woofer noise.

Portable and Durable

The tough, lightweight IRX115S is engineered to outperform larger boxes in a compact form factor weighing just 65.3 pounds. Its durable MDF enclosure features a tight-gauge, read more 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.

I ordered a used one last month "it was all they had" lol, but when I received it looked like new, and when I plugged it in WoW it totally surprised me with its really clean deep sound as well as the clean tone it gave. I have been DJing for over 10 years I have another pair of 15" powered subwoofers but they don't have the power this JBL has and this JBL blew them away. Now when they get the JBL IRX115S back in stock I am ordering another one.
