Panaray®MA12

Modular Line Array Loudspeaker

Key Features

• Designed to deliver high speech intelligibility in indoor
acoustically demanding spaces

• Music performance from 155 Hz to 12 kHz (-3 dB); for full-range
music performance, additional bass augmentation is required

• Wide horizontal dispersion for broad 145° coverage

• Available in black or white, paintable

Description

The Panaray®MA12 modular line array loudspeaker is designed
for indoor applications where speech intelligibility is critical
and speech r

eproduction is the main requirement. To deliver

full-range music performance, bass augmentation is required.

loudspeaker configurations. This loudspeaker is well-suited for
indoor applications such as houses of worship, auditoriums,
transportation hubs, atriums, malls, gymnasiums and multi­purpose spaces.
