Product Details ACP-55T
ACP-55T is the ADORN pendant loudspeaker for background and foreground sound in open-ceiling interiors. Its applications include hotel atriums, exhibition spaces, retail, restaurants and bars, providing music reproduction and intelligible speech from a suspended cabinet.
A 5.25-inch LF driver and 0.75-inch silk-dome tweeter provide a published maximum of 109 dB peak at one metre. The 150° conical pattern gives broad coverage below the cabinet, reducing the number of loudspeakers needed where the installation geometry permits.
A single-point suspension fitting is supplemented by a separate safety-cable attachment. The transformer tap selector is positioned at the top of the pendant enclosure and provides 70/100 V distribution settings or 16-ohm operation. Multiple units can be paralleled on a suitable low-impedance circuit.
Independent auto-resetting thermal fuses protect LF and HF. The baffle and enclosure carry the UL 94V-0 material rating. Martin Audio lists compliance with UL 1480A and CSA C22.2 No. 205-17.
The bezel-free grille releases through a bayonet fitting without tools. Black or white finishes match the ADORN on-wall family and can be painted to coordinate with the interior.
