Bosch LBC 3403/16 Outdoor Wall Mountable Speaker Light Gray

Designed for dependable outdoor mass notification, the Bosch LBC 3403/16 outdoor wall-mount horn speaker delivers clear, high-output voice and tone for security, surveillance and public-address systems. As part of Bosch's professional horn loudspeaker line, the LBC3403/16 combines a weatherproof IP65-rated enclosure and UV-resistant light-gray finish to withstand dust, rain and prolonged sun exposure. Its acoustic range (350 Hz to 10 kHz) is optimized for speech intelligibility and alert tones across large, open areas and perimeter zones.

Integrators benefit from a versatile wall-mount bracket and a compact footprint that simplifies installation on façades, platforms or poles. The horn accepts different driver units so sound pressure level and coverage can be tailored to campus, industrial or transportation applications. Provision for internal mounting of an optional line/loudspeaker supervision board supports monitored PA and emergency mass notification deployments where system reliability is critical.

Ideal for security, monitoring and emergency alerting across campuses, transit hubs and critical infrastructure, the Bosch LBC 3403/16 enhances situational awareness and response. Contact your Bosch reseller or order today to upgrade outdoor alerting and public-address capability.
