Martin Audio Adorn ACP-55T-W – 5.25" Pendant Ceiling Speaker, White Pair

Product Overview

The Martin Audio Adorn ACP-55T-W is a professional pendant ceiling speaker engineered for distributed audio and background music systems in high-ceiling commercial environments. Sold as a pair in white finish, this two-way passive loudspeaker delivers consistent, intelligible coverage across hotel atriums, exhibition halls, and retail environments. Its wide 150° conical dispersion pattern and 70V/100V line compatibility make it a practical choice for AV integrators designing large-scale commercial audio installations.

Product Description

Part of the Martin Audio Adorn commercial loudspeaker series, the ACP-55T-W pendant ceiling speaker combines high output capability with architectural discretion in a white (RAL9016) finish that integrates naturally into commercial ceilings and matches the Adorn on-wall loudspeaker range. The enclosure features a single-point suspension system with provision for a safety cable, meeting standard commercial rigging requirements for ceiling-mounted audio equipment.

The two-way driver configuration pairs a 5.25" (135mm) low-frequency driver with a 0.75" (19mm) silk-dome tweeter, producing 109dB peak SPL at 1 metre and a frequency response of 98Hz–20kHz ±3dB. The 150° conical coverage pattern reduces the total number of speakers required to achieve even SPL distribution, directly lowering material and labour costs in large-footprint installations.

The built-in multi-tap transformer supports 70V and 100V distributed audio line operation, with tap selection via rotary switch at the top of the pendant enclosure. The enclosure also supports 16-ohm low-impedance operation for direct amplifier connection. Both LF and HF driver sections are individually protected by auto-resetting thermal fuses. The bezel-less, bayonet-fit perforated steel grille can be removed without tools and accepts field painting. Browse the complete Martin Audio Adorn range at Creation Networks – Martin Audio.

Frequently Asked Questions

Does the ACP-55T-W include safety cable attachment points?

Yes. The pendant enclosure includes provision for attaching a safety cable in addition to the primary single-point mounting system, meeting standard commercial rigging safety requirements.

Can this speaker operate on both 70V and 100V distributed audio systems?

Yes. The built-in multi-tap transformer supports both 70V and 100V line operation. Tap selection is made via a rotary switch at the top of the enclosure. It also supports 16-ohm low-impedance operation for direct amplifier connection.

What amplifier is recommended for low-impedance operation?

Martin Audio recommends the VIA2004 four-channel Class D amplifier for low-impedance operation of the ACP-55T series.

What is the difference between the ACP-55T-W and ACP-55T-B?

The two models are acoustically identical. The ACP-55T-W has a white (RAL9016) finish; the ACP-55T-B is finished in black. Both match the corresponding colour variants of Adorn on-wall loudspeakers.

How wide is the coverage pattern?

The ACP-55T produces 150° conical coverage up to 7kHz (-6dB), which is notably wider than many competing ceiling pendant designs. This allows greater spacing between fixtures while maintaining even SPL across the listening area.

Is the grille field-paintable?

Yes. The perforated steel grille can be painted on-site to match any interior colour scheme without affecting acoustic performance.

What is the warranty period?

The ACP-55T-W carries a 5-year manufacturer warranty from Martin Audio.
