INSTALLED SOUND
The A55T is a two-way passive speaker with an elegant design
that is perfect for architectural environments that require highfidelity sound from an unobtrusive, ultra-compact enclosure.
It brings class-leading performance, reliability and value
to a wide range of commercial sound applications — from
retail outlets, bars and restaurants to corporate offices and
convention centres.
The A55T is the perfect choice for background and foreground
systems which require superior performance. Its Martin Audio
signature sound characteristic also provides a seamless sonic
transition within a multi-zoned complex using larger Martin
Audio systems such as CDD or BlacklineX.
Comprising a 5.25” (135mm) LF driver and a 0.75” (19mm)
silk-dome HF driver on a 110° x 80° horn, it handles 50W
AES, 200W peak and can produce 113dB peak output at 1
metre. It has a smooth frequency response and strong bass
reproduction that extends down to 65Hz.
The A55T incorporates a high-quality transformer for 70V/100V
line operation, with transformer taps selected by a rotary switch.

The recommended amplifier is the VIA5002 in conjunction
with a suitable line transformer. For full-bandwidth protection,
the low and high-frequency sections are individually protected
against overload.
Available in black or white as standard, it can be readily painted
to match any décor, and can be wall-mounted vertically or
horizontally using the wall bracket supplied.
The VIA5002 amplifier in combination with a Martin Audio
DX0.5 controller will be perfect partners for small scale
efficient installations, or with the DX4.0 controller for larger
more complex installations, which could then also be managed
by Martin Audio’s VU-NET control software platform.
The Martin Audio SX110 subwoofer will extend the bandwidth
of ADORN on-wall speakers and is ideal for foreground music
applications which require increased impact and low frequency
performance.
