The Compact and Powerful Subwoofer of the SONAR Series
Designed to fit at the core of the HK Audio SONAR range, the SONAR 115 Sub D combines a compact enclosure with an energy reserve comparable to 18-inch subwoofers. Its modern electronics maximize the 15-inch driver to deliver a clean and clear bass foundation, ideal for mobile applications and small to medium venues.
Who Is It For and What Are Its Uses?
The SONAR 115 Sub D is aimed at DJs, bands, service providers, and venues hosting audiences who seek a reliable plug & play solution. Whether in clubs, bars, multipurpose rooms, or outdoor events subject to neighborhood constraints, it provides the necessary low-end support while remaining easy to transport and set up.
Modern Control and Ready-to-Use Cardioid
Cardioid Mode Without Calculations
With two SONAR 115 Sub D units, switch to cardioid mode in seconds: place one subwoofer facing backward, select "Cardioid Rear" on it and "Cardioid Front" on the other. This achieves a strong bass reduction behind the stage, up to 34 dB, improving artist comfort and overall clarity.
2.1 Management and Intuitive DSP
The stereo inputs/outputs simplify setting up a 2.1 system with satellites. The LCD screen provides access to the 24-bit DSP: Bass Boost, adjustable crossover frequency, polarity inversion, and delay (0-10 m) to align the subwoofer with the tops. You can instantly tailor the response to venues and musical styles.
Roadworthy Design
The wooden enclosure, metal grille front covered with black acoustic foam, and MultiGrip handles ensure durability and ergonomics. The M20 flange allows pole mounting, and the subwoofer is prepared for transport wheels.

No problem with the order, however the delivery is not up to par. I ordered the HK 1500 D box and was asked for an additional charge for home delivery, except that to my surprise I had to go to the post office to pick up my purchase myself. Before that I tried to contact customer service for 3 days. Nobody even answers you by email. WOODBRASS is over for me. I am really disappointed. Run away and go to the competitor who at least answers you.
