Livonia, MI dual siren sound off and test September 5th, 2026. Great echos!

My first time sounding off all 16 drivers at once through my 3000 head off of a Federal Signal controller. You can tell that Mod easily outperformed my Whelen (thanks to having twice as many drivers as what mine can do). Me and Sam both had a great time together and I'd say this was worth it.
