Audio professionals looking for a powered subwoofer that complements the SONAR Xi full-range speakers will be impressed with the HK Audio SONAR 115 Sub D, a compact, active subwoofer with a 1500W peak amplifier that powers the 15" woofer that produces frequencies as low as 40 Hz with a maximum SPL of 128 dB. The SONAR 115 Sub D deliver high-quality sound and a whole catalogue of professional features at an affordable price point.At a Glance Professional 15" subwooferCardioid-compatible1500W peak performance Class-D amplifier24-Bit DSP with illuminated LCD screenProfessional, balanced XLR inputs and outputsRoad-ready features thanks to sturdy wood cabinet and black acrylic enamel coatingDurable quality thanks to high-quality materialsIntegrated DSP Bass Boost: On/OffMode: Normal/Cardioid Front/Cardioid RearPolarity: Normal/ReverseX-Over: 60 to 150 HzDelay: 0 to 33' for alignmentFront LED: Off/On/LimitDisplay Dim: Off/OnCardioid Principle The cardioid principle is all about cancelling out frequencies radiated to the rear. While medium and high frequencies can be radiated in directional patterns, low frequencies are spherical. This often leads to an unpleasant excess of low bass on and behind the stage. Organizers are also increasingly setting precise demands for sound distribution, for example, in marquees and urban stages.The SONAR 115 SUB D meets all the requirements, both mechanically and acoustically, to implement effective cardioid setups quickly and easily, reducing the low bass radiated to the rear by up to 30 dB. This not only makes performing on stage much more relaxed, but it also results in a better sound, as 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 setup (shown on the left) with two subs projecting forward boosts the sound pressure by level 3 dB in all directions. But what makes the SONAR 115 Sub D so special are its cardioid capabilities. It has two special presets that allow you to configure a cardioid setup, where the lower sub projects to the rear without the need for any complex calculations or time correction.To do this, simply direct the lower SONAR sub to the rear and select the Cardioid Rear preset, and direct the upper sub to the front, selecting the Cardioid Front preset. Now both subs can play perfectly together without having to make any further adjustments.
