Introduction
The new VHD2.18J is a direct radiating bass-reflex speaker containing two 18" high performance transducers. These 18’’
transducers are designed to withstand very high power levels. The optimised, high efficiency, bass-reflex design of the
VHD2.18J produces considerably more output than other similar double 18" enclosures. Constructed of Baltic Plywood,
integrated proprietary Flyware allows for fast rigging of multiple cabinets when they are needed to be flown. An ideal
subwoofer for any application where direct radiating bass speaker reproduction is required.
Acoustic Components
The VHD2.18 woofer technology is based around a custom made high efficiency, high power woofer design. The device
features two 18" woofers, with high temperature 4.5" (116mm) multiple layer aluminium voice coil assemblies, with
a double Silicone spider for optimised compliance. The advanced magnetic structure and ventilated voice coil gap
improves cooling dramatically, which in turn significantly reduces power compression. The woofer cone has been
specially developed to withstand the demands of high power and very low frequency extension.
Enclosure Design
The VHD2.18J is an optimised, high efficiency bass-reflex design, with a revolutionary new design characteristic
(patent pending) developed by KV2 Audio Engineering. This brand new design gives considerably more output than
other similar double 18" enclosures, whilst maintaining the full low frequency bandwidth. The cabinet is a Baltic Birch
enclosure featuring a large number of ergonomically designed parts that make it an easy speaker to set up and use.
There are 6 side handles allowing you to reposition the unit in a natural and intuitive manner. The VHD 2.18J Sub
woofer Module also employs low friction feet to enable easy movement and locking into other VHD 2.18J cabinets.
A unique new Flying system is fitted discretely within the enclosure to allow easy flying of single or multiple cabinets
using the KV2 Audio propriety certified Flyware system.
