FedSig Rumbler Solo Subwoofer

All the intersection-clearing punch of the Rumbler system from a single 12-inch subwoofer. The Rumbler Solo drops low-frequency tones that civilian drivers feel through their seats — up to 10dB more sound pressure inside nearby vehicles than a standard siren alone — while needing only one mounting location instead of two. Choose the speaker-only kit if your siren already has Rumbler capability built in (like the Pathfinder), or the complete system with its own amplifier and timer for any other siren.
