VHD2.21 - part number KVV 987 249
Ultra Low Frequency Subwoofer
Introduction
Originally designed for Super Live Audio as part of a VHD system, the VHD2.21 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 VHD2.21 boasts tight, fast delivery and extreme dynamics, even at higher bass frequencies – qualities rarely found in
such a large unit. One 2.21 can be driven by a single VHD3200. Whilst larger than KV2 Audio’s existing subwoofers it still
fits in with the company’s philosophy of providing maximum performance from within a compact footprint.
Acoustic Components
The VHD2.21 woofer technology is based around very high efficiency, high power woofer designs. The device features
two 21"cones with a high temperature 4" (100mm) inside/outside epoxy baked reinforced cellulose voice coil
assembly, that undergoes multiple baking and curing processes as well as advanced neodymium advanced ventilated
magnetic structures with complex cooling systems. The woofer cone has been specially developed to withstand the
demanding environment within the Bandpass chamber.
Enclosure Design
The VHD2.21 is a full size low port loss Bandpass design, in a substantial Baltic Birch enclosure featuring a large number
of ergonomically designed parts that make it an easy speaker to set up and use.
Internal steel bracing bars are utilized to ensure rigid integrity and there are 6 side handles and two top and bottom
that make it manageable to pick up and reposition the unit in a natural - instinctive and intuitive balanced manner.
The VHD2.21 Sub woofer Module employs 4 fixed cart wheels feet to enable easy transportation and there are
numerous dimples to allow locking and securing of existing and other KV2 Audio VHD cabinets .
