Product Details A55
A55 is a passive two-way ADORN loudspeaker for commercial interiors needing music and speech from a discreet enclosure. Its applications include retail, bars, restaurants, corporate offices and convention spaces. The Martin Audio voicing also supports a consistent transition between zones using larger CDD or BlacklineX systems.
A 5.25-inch LF driver and 0.75-inch silk-dome HF driver operate through a 110° × 80° horn. Power handling is 50 W AES and 200 W peak, with a maximum output of 113 dB peak at one metre. The response extends to 65 Hz at the −10 dB point.
The 16-ohm nominal impedance allows several loudspeakers to share one appropriately loaded low-impedance amplifier channel, including the manufacturer-listed VIA2004. LF and HF sections are individually protected against overload.
Black and white versions are supplied as standard and can be painted for the interior. The included wall bracket supports portrait or landscape mounting. Outdoor IP54 protection requires the optional weatherised connector cover.
Martin Audio pairs A55 with VIA2004 amplification and DX0.4 or DX0.6 processing for small installations. DX4.0 provides the system-processing option for larger, more complex installations managed through VU-NET.
For foreground music needing more bass impact, the manufacturer identifies SX110 as the subwoofer partner for the ADORN on-wall range. It extends the low-frequency bandwidth while the wall loudspeakers retain their discreet coverage role.
