Whelen Howler Low Frequency Siren - Blazer EV

Force distracted civilian drivers to yield with the Whelen Howler Low Frequency Siren System for the Chevrolet Blazer EV PPV. Modern vehicle cabins are heavily insulated, and drivers are constantly distracted by loud stereos and smartphones. A standard 100-watt high-frequency siren simply bounces off these cars at highway speeds. The Whelen Howler is the ultimate countermeasure. Acting as an add-on to your primary siren amplifier, it captures the tone and drops the frequency, projecting a massive, deep bass wave that drivers physically feel vibrating in their chests, demanding immediate attention at dangerous intersections.

Key Features & Upfitter Specs

  • Low-Frequency Penetration: Generates deep bass tones that easily penetrate heavily insulated vehicle cabins and urban noise pollution, ensuring your warning signal is felt before it is seen.
  • Primary Siren Synchronization: Operates seamlessly alongside your primary 100/200W siren amplifier, synchronizing with the sweeping or Hi/Low tones to create a massive, multi-layered acoustic wall.
  • Timer-Controlled Safety: Includes a built-in safety timer (selectable from 7.5 to 60 seconds) that automatically deactivates the Howler to prevent excessive low-frequency exposure to the vehicle operator.
  • Blazer EV Specific Hardware: This complete kit includes the Howler amplifier, heavy-duty speakers, and the exact vehicle-specific mounting brackets required for the Chevrolet Blazer EV PPV.
  • Selectable Tone Styles: Utilizing Scan-Lock technology, operators can customize the exact frequency style (1/4 tone, 1/2 tone, or composite) to achieve maximum penetration for their specific environment.
