The Feniex Hammer Low-Frequency 100-Watt Siren is the perfect add-on for your current siren system! The Hammer produces a low-frequency tone that shakes the ground and alerts other drivers that you're approaching. You can create even more power by adding two Feniex Hammers to your set up, creating a 200-Watt earth rumbling alert. The Hammer is designed to alert drivers ahead of you or when approaching an intersection. It is intended to supplement your current siren system, not replace it.

    Very loud for a single speaker

    Posted by K. Hatfield on 17th Dec 2019

    Real attention getter. Way easier to install the single speaker instead of the dual systems. And it can stand alone.

    Oh Yes!

    Ever since I heard a ‘rumbler’ system, I have wanted one. The Feniex Hammer is a fantastic addition to my patrol car and I am glad that I got one. Installation was super easy and I like that it’s a 1 piece system compared to the 3 piece rigs of the competition. $200 well spent.

    Works great, but not all sirens are compatible. Works great with the handheld Typhoon siren.
