A word about speakers. When we were working on the F3, our first engine with
speakers, we put them in the roof pointing up. Dick Maddox CEO of Lionel came
over to chat and asked me what we were working on (he actually came over to
invite us to be a TMCC participant, but that is another story). I showed him
the F3 shell and after a careful inspection he told me we should have put the
speaker in the chassis pointing down. He said that Neil Young had done a ton of
research on speaker location in model trains and they found it was best to
bounce the sound off of the roadbed. At that time it would have cost to much for
us to modify the chassis so in our F units they point up. We did listen to him
for our 2-8-0 and placed the speaker in the tender and pointed it down. When we
did the modifications for the upcoming NW2 (and to be used on the SW8/9), to add
the speaker to the chassis would remove too much weight. So they were put in an
air tight chamber in the front of the shell, just behind the front grill. So,
we had speaker up, down and forward. When we discovered we could add a hi-base
speaker to our older SW9s, we pointed them down over the front truck.
The truth is, to my ears they all sound about the same in a room with a normal
height ceiling. I was surprised that the smaller speaker in the switchers
sounded just as loud and clear as the larger speaker in the F units. This is
with the same decoder and the settings. I will admit, when our trains are in a
show hall with 30+ foot ceiling the prime mover sound of our diesels almost
disappear. You can always hear the bell and horn. The 2-8-0 sounds are not as
affected as the diesels...
