Di8 DC

Product Description

esigned for a wide variety of sound reinforcement applications, the Tannoy Di8 DC is a high

D
performance, ultra compact surface mount weather resistant loudspeaker. A full bandwidth
loudspeaker designed for commercial, professional and residential applications where environment
durability and high quality sonic performance are required. Indoor or outdoor, these speakers are
ideally suited to stereo or monaural background or foreground music systems in such applications
as diverse as theme parks, retail premises, restaurants and cafés, corporate audio visual, residential
developments and houses of worship.

Renowned for its extraordinary power handling, high sensitivity, extended frequency response and
very low distortion, Tannoy’s Dual Concentric™ provides a wide and controlled dispersion ensuring
optimum coverage. By placing the high frequency drive unit physically inside the low frequency
driver, Tannoy engineers have created a true point source that exhibits constant directivity and
unparalleled linearity. Perfect for this type of application, the driver system generates a spherical
wave front unaffected by energy loss at the crossover frequency in either vertical or horizontal
planes; allowing highly flexible speaker placement on the wall or ceiling with no compromise to
performance and vocal intelligibility.

The Dual Concentric™ driver in the Di8 DC uses a 200mm (8.00") complex multi fibre paper pulp
mix for the mid bass cone to achieve optimum acoustic performance, while a comprehensive resin
treatment process ensures the materials weather resistance. The concentrically positioned 25mm
(1.00") HF unit has a ferrofluid cooled titanium dome, with a neodymium magnet system, equipped
with dynamic high frequency protection.

Available in textured black or white painted finish with matching rubber trims, the
outstandingly durable and scuff resistant, high impact polystyrene (HIPS) Di enclosure is weather
resistant, rated IP64 to EN60529 (IEC529); a construction fully optimised for
consistent performance in adverse conditions indoors or out.

Modification is possible by application of alternative colour trims. Two standard colour trim
options are available from stock; enabling black or white product to be supplied factory pre-fitted with
either red or blue trims.

Other trim colours can also be created to suit specific requirements, but only as a special order
customisation subject to minimum order quantities. Primarily aimed at corporate branding
applications, this aesthetic flexibility will also enable colour coordination for larger installs.

Transformer version - the Di8 DCt

The Di8 DCt model option is equipped with an internally mounted low insertion loss line
transformer for 70V or 100V distributed sound applications. Wattage taps are easily configurable to
the following settings via an easily accessible rotary tapping switch, which is bottom panel mounted
under the rubber trim.
70V: 60W / 30W / 15W / 7.5W / OFF & Low impedance operation
100V: 60W / 30W / 15W / OFF & Low impedance operation
