VHD2.21 – Ultra Low Frequency Subwoofer
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. There is also a flyable version available – VHD2.21R (KVV 987 496) with additional fixings and requirements for the VHD4.21 Flybar (KVV 987 398).
Applications
Especially designed to add extreme low frequency-last octave extension with exceptional high output to the VHD2.0 and VHD1.0 in conjunction with other VHD subwoofers
- Large scale live music and playback performance
- Hire and Production
- Large Concert venues
- Cinema
- Nightclub
- Fixed installation
- Easily incorporated into multiple system projects with ES and SL products
