Martin Audio ACS-55T-W 5.25 Inch Passive Two-Way Ceiling Speaker

The Martin Audio ACS-55T-W 5.25 Inch Passive Two-Way Ceiling Speaker brings full-frequency response, consistent coverage and intelligibility to a wide range of architectural environments from hotels and concourses to retail outlets, bars and restaurants.

Comprising a 5.25” (135mm) LF driver and a 0.75” (19mm) silk-dome tweeter, the ACS-55T-W produces 113dB peak output at 1 meter and has a high-fidelity sonic character ideal for both music and speech reproduction. Its ported bass reflex design and back can with generous internal volume maximizes low frequency output and delivers strong bass that extends down to 62Hz.

The wide 150° conical coverage of the ACS-55T-W reduces the number of speakers required for even coverage leading to a reduction in installation cost.

It incorporates a high-quality transformer for 70V/100V line operation, with transformer taps selected by a rotary switch accessible behind the powder-coated, perforated steel grille. The switch also provides for 16-ohm low impedance operation enabling four or more speakers to be driven in parallel from a single amplifier channel. For full-bandwidth protection, the low and high-frequency sections are individually protected against overload by auto-resetting thermal fuses.
