5.25" Passive Two-way on-wall Loudspeaker

Where to Buy or Rent

The ADORN A55 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.


  • Contemporary, unobtrusive design
  • High output capability
  • High fidelity sound
  • Low and high-frequency overload protection
  • Vertical or horizontal orientation
  • Wide 110° x 80° coverage
  • Wall bracket included
  • 5-year warranty


  • Retail outlets
  • Cafes, bars and restaurant chains
  • Hotels and convention centres
  • Educational facilities
  • Corporate offices

The A55 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.

With a nominal impedance of 16 ohms, multiple speakers can be driven in parallel from a single channel of a low impedance amplifier, such as the Martin Audio VIA2004, thereby maximising efficiency and minimising cost. 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. In addition, for general outdoor use the cabinet only requires the additional waterproof connector cover.

The VIA2004 amplifier in combination with a Martin Audio DX0.4 or DX0.6 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.
