@@thunderaarcanis98 An omni 6x4 DSA will absolutely smoke the 1212 in terms of output all day every single time. As much as I love the EOWS 1212, it’s only a 1200 watt siren with a single 100watt driver per horn x12. This DSA 6x4 is a 2400 watt siren, with six 100watt drivers & horns per array. I’ve heard many DSAs & 1212s in person, the DSA wins every time.
