Frontline Emergency Vehicle Conversions have put together this brilliant video of the Digital 100 Watt Low Frequency Rumble Speaker, demonstrating the low frequency rumble tone provided by the 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.
Please note that this speaker is only compatible with the MCS-DDSA 200 Watt Digital Siren!
