The JBL IRX115S powered subwoofer transforms your sound system from good to ground-shaking. This 15" powerhouse extends low-frequency response down to 35 Hz, delivering the deep, room-filling bass that makes audiences feel every beat in their chest. The IRX115S bridges the gap between professional-grade performance and budget-friendly practicality.
Serious Bass Performance That Doesn't Mess Around
When it comes to delivering knockout sound, every beat matters. Whether you're commanding the dance floor, energizing a fitness studio, or amplifying a live performance, top-notch audio gear can make or break the experience. That’s where the IRX115S steps in — an impressive subwoofer that blends jaw-dropping bass performance with surprising portability and unbeatable value.
15" Woofer with 3" Voice Coil: This isn't your average speaker driver. The oversized voice coil handles serious power while delivering smooth, detailed low-frequency response that stays clean even when you push it hard.
1,300 Watts of Pure Power: With enough juice to fill large venues, this subwoofer generates up to 128 dB of maximum SPL. Translation? Your bass will be heard and felt, exactly as intended.
Selectable Crossover Points: Choose between 80 Hz, 100 Hz, and 120 Hz crossover settings to perfectly match your main speakers. No guesswork, just optimal system integration every time.
Built for the Road, Designed for Reliability
The IRX115S understands that professional audio gear needs to survive the real world. Its road-tested MDF cabinet features a reinforced honeycomb bevel grille that protects the driver while maintaining acoustic transparency.
Lightweight Construction: At 65.3 pounds, it's surprisingly portable for a 15" powered subwoofer. The thoughtfully placed ergonomic handles make loading and unloading a one-person job.
Tuned Ported Enclosure: The precisely engineered port design enhances output while reducing unwanted woofer noise, ensuring clean bass reproduction at any volume level.
JBL's 100-Hour Stress Test: This subwoofer has been torture-tested to ensure it keeps performing show after show, season after season.
Plug-and-Play Features
The IRX115S keeps connection simple with dual XLR combo inputs and dual XLR outputs, plus a convenient polarity switch to optimize system response. The built-in pole mount integrates seamlessly with IRX108BT and IRX112BT speakers, creating a complete sound system that's greater than the sum of its parts.
Dual XLR I/O: Connect multiple sources and daisy-chain to additional speakers without external mixers or splitters.
Polarity Switch: Fine-tune your system's response with a simple flip of a switch — perfect for different room acoustics and speaker configurations.
Standard Pole Mount: Elevate your main speakers for better coverage and cleaner stage setup.
The Bottom Line: Professional Sound Made Accessible
The JBL IRX115S delivers the deep, powerful bass that transforms good performances into unforgettable experiences. It's engineered with 70+ years of JBL innovation, built to survive the demands of regular use, and priced for performers who demand professional results without the professional price tag.

Buy covers for them if
Buy covers for them if transporting frequently as the corners will get dinged up because there is no protection on them and the material is mdf or similar. Will probably put some amp corners on them. They sound good.
