Designed is response to call for a High Output Ultra low frequency subwoofer solution, the VHD 2.21 is a double 21” subwoofer with an input power handling capability of 3200W and output levels of 146dB for two cabinets. Whilst larger than KV2 Audio’s existing subwoofers it still fits in with the companies philosophy of providing incredible performance from within a compact footprint.

Originally designed for Super Live Audio as part of a VHD system it is voiced for both Live Music but also excels in the field of Club and Dance Music. In this situation it works very effectively, operating down to 25Hz, alongside other VHD products, the smaller ES range, or as an incredible stand-alone subwoofer that can complement any other manufacturers systems.

Unlike traditional 21” subwoofers that are typically designed as more of an effect subwoofer, the VHD 2.21 boasts tight, fast delivery and extreme dynamics, even at higher bass frequencies – qualities rarely found in such a large unit.



  • Subwoofers for medium to large live music and playback touring applications.
  • Very high quality fixed installations working as the above.
  • Professional portable PA systems for large format AV speech and multimedia playback.
  • Very High Definition dance systems providing the ultimate low frequency reproduction for clubs and events.
