DETAILS

HK Audio SONAR 115 Sub D – 15” Active Subwoofer with 1500W Class-D Amp, DSP & Cardioid Mode.

High-Powered Bass Extension for Live Sound, DJs, Bands & Installed Systems.

The HK Audio SONAR 115 Sub D is a high-performance 15" active subwoofer designed to deliver deep, controlled bass for live music applications, mobile DJs, bands, and venues. With 1500 watts of peak power and HK Audio’s renowned acoustic engineering, it offers a powerful low-end foundation for SONAR full-range speakers—or any professional PA needing extended bass response.

A built-in 24-bit DSP and bright LCD screen allow easy control over crossover frequency (60–150 Hz), polarity, delay, and Bass Boost, while the robust Class-D amplifier and long-excursion woofer produce an impressive 128 dB max SPL. Its bass reflex enclosure ensures efficient low-end output from 36 Hz upwards.

Advanced DSP & Cardioid Mode for Stage Control

The SONAR 115 Sub D features an intuitive interface for real-time sound shaping. One standout feature is the built-in Cardioid Mode—a rare inclusion at this price point—allowing you to reduce unwanted bass energy on stage. Simply connect a second sub facing backward and activate the Cardioid Rear and Cardioid Front presets to significantly improve front-to-rear SPL ratio.

Other useful presets include a dedicated SONAR mode for full-range system integration. Rear-panel controls also let you dim the front LED and LCD for discreet stage use.

Road-Ready Construction & Flexible Setup

Housed in a rugged wooden cabinet with MultiGrip handles, steel grille, and M20 top-mounted pole socket, the SONAR 115 Sub D is built for professional use. Optional wheel assembly compatibility makes transport easier for touring users. Balanced XLR/jack combo inputs and XLR thru outputs allow seamless integration with a wide range of PA systems.

HK Audio's 5-year manufacturer warranty offers added peace of mind for professional users.
