Designed to take full advantage of the low frequency rumble tone function available from our 200 Watt Digital Siren (MCS-DDSA).
The speaker utilises the 'ground effect' producing penetrating/vibrating low-frequency sound waves that can be physically felt. Highly effective in dense urban environments with heavy vehicle traffic, getting attention and clearing traffic more effectively than a standard siren tone.
This unit can be used independently or simultaneously with other siren speakers to produce multiple tones.
