135hz Bass whistle chamber.mp4 

fun little weekend project here is a 135hz edgewind whistle powered by a 2hp dust collector blower. tone is a bit harsh as I'm seriously over-blowing the unit with the big pump but only took 3 or 4 tries to clean it up to this level of performance, really get's annoying after a bit at 115+ db Want to make the neighbors crazy light this one up in your house and go to a late movie.
