    KV2 Audio EX1.5 - 500-Watt 15” active subwoofer

    SKU: GDSKV2EX1.5
    • There are lots of powered speakers, but at KV2 Audio building an active speaker goes beyond bolting a Class D amplifier to the back of a box. We work towards creating the best technology in each distinct discipline, and then integrate each step into a powerful package within the context of a truly remarkable audio system. 

      The EX range represents the pinnacle in small format active technology available in the world today. The market has been flooded with active speakers since their popularity flourished in the late nineties. It was indeed KV2’s founder George Krampera that led this revolution with the development of the ART range at RCF. George soon realized the true secret to active loudspeaker design was not just building powered speakers but developing amplifiers that are perfectly matched to the transducers so every component is optimized.
