EX2.5 MkII - Low Frequency Solution


The EX2.5MkII is a double 15" subwoofer and the ‘active’ brother of the ES2.6 passive bass module. It provides real depth and power where high bass output is required. The product uses the same low frequency amplifier found inside the EPAK2500/2500R and features in-built stereo crossovers, high pass outputs, and full overdrive protection. It also features a new speaker level output on an AP4 connector to drive one additional passive ES2.6 subwoofer from its own internal amplifier. (Not to be used with a passive ES2.5)



  • Professional, Baltic birch construction with wear resistant polymer coating
  • 137dB sustained output 140dB peak (when used with an ES2.6)
  • 1600W high efficiency, current enhancing, switching low frequency amplifier
  • Speaker level AP4 output to drive one additional passive ES2.6 subwoofer
  • Complete on board subwoofer management including equalization, crossover, filters, amplifier overdrive protection, output level and phase controls
  • Excellent reproduction of sub bass frequencies with high transient content at high output levels
  • Stereo or Mono inputs with through signal outputs and 125Hz High Pass outputs
  • Two 15" high output, low frequency drivers with 4" (100 mm) inside/outside, epoxy baked, high temperature, voice coil assembly and ferrite magnetic structures
  • Four propietry side handles for simplified handling and carrying
  • Heavy duty front grille to work with the innovative new EX2.5 magnetic cart
  • Acetyl copolymer high impact, low friction feet are located on two sides allowing vertical or horizontal set up and easy cabinet movement Feet lock in to the new ES subwoofers
  • Six internal corner braces with twelve M10 suspension points M20 top hat for pole mounting applications
  • LED indicators for signal present, limiter, thermal condition and power ON status



Specifically designed to accompany and compliment the EX Mid High speakers to create a true full range high output system

  • Easily incorporated as a system with multiples of any of the EX range
  • Scalable into multiple-larger systems
  • Fixed installations

    KV2 Audio EX2.5 MkII -1600-Watt dual 15” active subwoofer

    SKU: GDSKV2EX2.5
    • 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.
