Applications
Features
This direct radiating dual 18” subwoofer cabinet is designed to partner Tannoy’s VQ Series full
range installation loudspeakers, the VNET 218DR is perfect for applications where increased
headroom is required for high definition sound reinforcement at low and ultra low frequencies.
Extending the frequency response of the system down to 31Hz makes the VNET 218DR ideal
for effects in live music performances in a multitude of environments including open-air, arena
and theatres as well as large dance club and concert sound applications. This subwoofer is
capable of delivering deep and powerful bass at high sound pressure levels with extremely
low distortion and power compression, while all the time maintaining a uniform frequency
response throughout its dynamic range. The large port areas ensure minimal turbulence
even at high output levels.
This versatile, no compromise, all-purpose subwoofer is designed for the most demanding
installed audio applications. The VNET 218DR provides exceptional output, high reliability
and outstanding sonic performance providing low and VLF reproduction.
The VNET 218DR is equipped with 16 x unobtrusive recessed carrying handles and 16 x
10mm flying inserts. The cabinet is also fitted with 4 x rubber feet and recessed points are
provided on top for secure and safe stacking of multiple subwoofer enclosures.
The modular approach of amplifiers, processing, monitoring and drivers designed into each
loudspeaker enables acoustic optimization for the speaker to perform as a unified whole.
The intuitive VNET™ software, integrated processing, tuning control, performance diagnostics
and protection produces an easy to deploy, exceptionally high performance networkable
loudspeaker. System commissioning and ongoing network control, incorporating real time
diagnostics of electronics and drive unit, are all managed by the exclusive VNET™ software
package. Supplied with each unit, this intuitive Windows tool controls all critical install,
commissioning and performance monitoring functions.
The VNET 218DR consists of twin 458mm (18.00”), high efficiency drive units producing
106dB/W, with a 100mm (4.00”) voice coil. The twin drivers are mounted in an immensely
robust and heavily braced 500-litre cabinet, available in either black or white, which is
constructed from 18mm (5/8”) multi-ply birch hardwood. Custom colour finishes are also
available upon request.
Product Description
VNET™ Network
Each VNET 218DR sub is fully VNET™ compliant. VNET™
supports free network topology so that the loudspeakers can
be arranged in a daisy chain, linked in a star configuration or in
any combination of both. Implementation of the network
between nodes is via high quality rugged Neutrik Ethercon
connectors, which are compatible with standard RJ45 plugs,
and CAT5 cable. Each speaker has a unique address for
auto-location on the network.
An RS485 interface is used for the serial data, with a twisted
pair to send and receive information to a high number of nodes
over very long distances. Operating a shared bus system, so
that a single computer can control any node on that bus, also
means that status information can be gathered from any of the
devices. The RS-485 differential signal is very robust, while its
noise immunity and long-distance capability ensure it is one of
the most popular communications methods used in industry.
Only data to control setup functions and ongoing system
diagnostics is carried over the network.
