Leslie Tyfons 300 and 425. Bigger than 20 train horns ;-)

Simultaneous honking of my Leslie Tyfons 300 and 425, for the full laker sound. The horns blow approximately 106 and 64 Hz in this clip, which is musically a major 6th interval. Combined, the horns weigh over 800 pounds. In this clip, the 120 gallon tank starts at 165 psig, and by the end of the last toot, it’s down to 48 psig.
