The EM60P-150W/11OHM is a high-performance 150W speaker featuring an 11-ohm impedance and durable aluminium housing. Delivering a powerful 115–133dB output across a 180–7000Hz frequency range, it has been engineered to accommodate varying siren system voltage tolerances for consistent, high-impact sound performance.

Designed for flexible installation, the speaker supports three optional cowl systems, with additional tip/cowl configurations available to suit a wide range of vehicle types and space constraints. The kit includes the speaker/amp unit with mounting bracket and fixings; tips and cowls are ordered separately to match specific application requirements.

Typically mounted within the engine bay, the EM60P-150W/11OHM is suitable for vehicles ranging from compact cars to large fire appliances. It is predominantly paired with Redtronic’s EM500 siren but is compatible with most 100W siren systems.
