Martin Audio ADORN ACP-55T 5.25" Pendant Speaker
The ACP-55T is the pendant member of the ADORN family, for rooms with no ceiling to cut into: exposed services in a warehouse conversion, an atrium, a covered walkway. It hangs on its own cable and carries the same 5.25" coated paper cone and 0.75" silk dome tweeter used across the ADORN ceiling range, crossing at 3kHz with auto-resetting fuses on both sections.
Because it radiates into full space rather than a ceiling plane, sensitivity is 86dB and maximum output 109dB peak, with 150 degree conical coverage to 7kHz and response to 98Hz within 3dB. The enclosure and baffle are UL 94V-0 rated ABS with a powder-coated perforated steel bayonet grille, available in black or white. It is 16 ohm rated at 50W AES with 70V taps at 30, 15, 7.5 and 3.75W and 100V taps at 30, 15 and 7.5W, and it is certified to UL 1480A and CSA C22.2 No. 205-17 for ceiling suspension.
