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 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.
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 (sold separately) 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 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.
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, 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.
With the IRX Series, perfect sound is just a button push away. Simple settings adjust crossover and polarity to optimise system sound in any space. Pair the IRX115S with IRX Series powered loudspeakers and access Bluetooth audio streaming, dbx automatic feedback suppression, ducking and EQ presets to sound your best in any space.

Nice upgrade for Ortofon
Thank you for the friendly service & I’m very happy with the new needle. The pick up volume is noticeably louder than my old Ortofon DJ Pro.
I’ll have to come back and grab a second needle to even out my set up – see you soon ;)

This is the one you want!
Stop looking, this is the one. The team at Mix Foundation for you sorted. Best gear and best price with invaluable service.
You found what you need!
This bag is awesome, room for cables too - many bags don’t have space for the power or cables bur this one does.
And you know UDG is the DJs choice of cargo - always has been.

Great portable speaker.
Loving this new addition. No cables needed and very low latency. Can't even notice it. Great for being portable and I use it as a sub in my music room. Battery life is great and it's easy to set up.
Does the job perfectly and mix foundation shipped it to me in record speed.

Kinda essential upgrade
Thanks for the advice and quick postage. Upgraded from 2M red to the blue stylus. Night and day in terms of accuracy. Don’t think just buy the blue if you have a red currently. Not an audiophile but difference was extremely noticeable. Put on a project debut carbon.

Great mixer!
Loving my new mixer. It's great to get rid of extra cables for my old sound card, and I'm enjoying all the extra effects that my DJM 800 didnt have. This was delivered really quickly and there was great communication from Mix Foundation.
