It also features comfortable aluminum handles and four rear-mounted casters for easy portability and setup. Enjoy the cleanest and clearest music with this innovative and convenient design. Keep Bass In Its Place Most subwoofers emit sound in all directions which often results in troublesome low-frequency build-up. The innovative K Cardioid Subwoofer is designed to eliminate low-frequency build-up, and the potential feedback issues that can arise when these uncontrolled frequencies move back towards on-stage microphones. Situated within a single compact enclosure, the subwoofer reaps the benefits of a cardioid subwoofer array and is ideal for mobile entertainers, rental professionals or any medium sized venue where low-frequency energy needs to be controlled without losing punch. Extensive DSP Technology The K Cardioid Subwoofer features the latest DSP technology. Directivity Matched Transition offers consistent directivity, volume and sound pressure across the whole frequency spectrum. Extended low-frequency response is provided by continually managing low-frequency transients, providing clarity on the starts of notes or drum hits. Finally, the GuardRail protection protects the amp module from disruptive clipping. Light & Rugged Construction The K Cardioid Subwoofer is contained within a rugged, robust, and lightweight ABS material. This enclosure delivers enhanced clarity due to the rigid internal components, and is far more robust than the conventional plastic surfaces. This ensures that this subwoofer can withstand the rigors of live performances.

Each speaker within the system features extensive digital signal processing technology (DSP) to deliver sonic clarity and total output that surpass what is expected in regards to system size and weight.
