[MOSFET]

There is no way in my view to use a horn that low.

Remember Richard Clark's Buick? The "winningest" car in IASCA history? Now
THOSE horns probably could play down to 150Hz, they were MONSTERS (they were
so large, they were difficult to pick up)!!!!!!

To AntiSpmammer: You may want to try to track down Rickard Clark and ask for
his suggestions regarding a horn that will play that low (he practically
invented the concept of horns in the car, and is TRULY in expert in this
area). Try looking at "Autosound 2000", the company he and David Navone
started.
