Which dual tone chopper do you prefer for the Thunderbolt series? Your choices are 4/5 port from the model 2t, or 5/6 port designed exclusively for the Thunderbolt. It is kind of hard for me to decide between the two! The 4/5 port produces a lower pitch which is more likely to penetrate better than the 5/6 port. The 5/6 port makes the Thunderbolt sound mighty, powerful, and MEAN! Any dual tone thunderbolt sounds mean to get your attention! In case you're wondering, I prefer the 5/6 port rotor, as I prefer the minor 3rd.

Federal Signal Thunderbolt Series, still the King of Air Raid Sirens!
