The ADORN A55T is a two-way passive speaker with an elegant design that is perfect for architectural environments that require high-fidelity 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.
