The Martin Audio ADORN A55 in white is a two-way passive loudspeaker that delivers superior performance from a compact, elegantly designed enclosure. Suited to background and foreground music systems in retail, hospitality, corporate and leisure environments, the A55 provides Martin Audio’s signature sound with a white finish to blend seamlessly into lighter interiors.
With a nominal impedance of 16 ohms, multiple A55 speakers can be driven in parallel from a single channel of a low-impedance amplifier such as the Martin Audio VIA2004. This maximises efficiency and reduces system cost in multi-speaker installations.
5.25″ LF driver with 0.75″ silk-dome HF on a constant-directivity horn
16-ohm impedance allows parallel drive from a single amplifier channel
Strong bass reproduction extending down to 65 Hz
Wide 110° x 80° dispersion for consistent coverage
Seamless sonic transition with larger Martin Audio CDD and BlacklineX systems
Individual LF and HF overload protection
Includes multi-angle wall bracket
White finish — black version also available (A55)
This is the low-impedance version without 100V line transformer. For 70V/100V distributed systems, see the A55T-W. An optional IP44 weatherising connector cover (AIPKIT-W) is available separately.
