HK Audio Sonar 115 Sub D is an active subwoofer with 15” driver with DSP and integrated mixer . It includes a volume control and 3-band equalization for each channel that can be adjusted intuitively using the rotary knob and the color display . Thanks to the free SONAR REMOTE app (for iOS and Android), all functions can also be controlled remotely for greater convenience.

Revolutionary technology, cutting-edge development tools, and advanced manufacturing methods—combine all of these factors with decades of audio expertise, and very special things can happen. That’s exactly what happened with the new SONAR loudspeaker family: it’s the first of its kind to deliver premium sound at an affordable price.

The Sonar Remote application

The SONAR REMOTE app for iOS and Android tablets and smartphones is the fastest and easiest way to control the built-in digital mixer. It lets you control all the settings and functions of the SONAR Sub D models, including the 3-band EQ parameters. You can also save scenes and presets to have them available on demand, controlling parameters such as frequently used microphone adjustments, changed SONAR Sub D settings, or base configurations for different positions.

All settings changed in the app are displayed simultaneously on the SONAR Sub D speaker display and vice versa! Both displays synchronize in real time.

Cardioid emission of the HK Audio Sonar 115 Sub D subwoofer

The cardioid principle is all about cancelling out frequencies radiated to the rear. While mid and high frequencies can be radiated in directional patterns, low frequencies are spherical. This often leads to an unpleasant excess of bass above and behind the stage . The SONAR 115 SUB D meets all the requirements, both mechanical and acoustic, to implement effective cardioid configurations quickly and easily, reducing bass radiated to the rear by up to 30 dB ! This not only makes stage performances much more relaxed, it also results in better sound, as the microphones no longer pick up unwanted low frequencies. A second SONAR 115 Sub D can be used to increase the sound pressure level in the bass range. The classic full-stack configuration with two forward-firing subwoofers increases the sound pressure by 3 dB in all directions. But what makes the SONAR 115 Sub D so special is its cardioid capabilities. It features two special presets that allow you to set up a cardioid configuration, where the lower subwoofer projects backwards , without the need for complex calculations or timing corrections.

To do this, simply aim the lower SONAR sub to the rear and select the Cardioid Rear preset , then aim the upper sub to the front, selecting the Cardioid Front preset . Now both subwoofers can play perfectly together without having to make any further adjustments.
