The 100 Watt Low Frequency Rumble Speaker – Digital 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.
Please note that this speaker is only compatible with the MCS-DDSA 200 Watt Digital Siren!
