These speaker pairs are specifically designed for use in ELA sound systems. Their 2-way system ensures high sound quality and speech intelligibility. The speakers are equipped with a transformer for operation in 100V systems but can also be directly connected to a low-impedance amplifier output. The adjustment of the connection power is done via a rotary switch. With their mounting bracket, the speakers can be installed on walls or ceilings. Thanks to their weatherproof enclosures (protection class IP 65), the speakers are also suitable for outdoor installation.
