Tom,
Thanks for sharing your thoughts on this. I agree with everything you have
said. Unless there is/was a federal saftey standard for this sort of thing, as
a practical matter I cannot see much difference either. I like your reasoning
regarding the wider dispersion of the lower frequency horn. It is a theoretical
reason for handing, although at the frequencies involved it may not make much
difference from a practical sense. It also occurred to me that given the RHD
world from which the cars came, they were setup for context, if a distinction
was made at all. As an aside, it would be curious to know if the Alpine owners
have noticed anything meaningful on the placement.
I cannot see this being a concours issue either, although it would be easy
enough to check without a frequency analyzer. The lip of each horn has either a
fairly large "L" or "H" stamped on the front bottom part of the opening and
easily can be seen through the grill opening. Maybe next time I am at a
national event I will make my own little survey.
FWIW, physically, the horns are mirror images of each other with spirals/snail
trumpets that square off at the front.
In any event, I am just moving on.
Thanks again, Gene

I do not know what the factory installation was of the low/hi horns.
However, there is some (probably very, very) minor logic to what I'll
present:
The lower the frequency of a sound, the more unidirectional it is. The
higher the frequency the more directional it is. So, assuming the purpose
for the horn is to alert say... someone running into the street (as an
example) it would make sense to have lower frequency horn on the drivers
side (USA). The reason being the added side distance to the person would
better be heard by a lower frequency. That reason is probably ridiculously
nit picky on my part, but the only reason I can see for having a
determination for horn placement. And, if it were actually true then the
country of shipment would have different horn locations based on what side
of the road was driven on.
If the horns have different physical structures (I don't know) then I can
see the need to place them as shipped for concourse accuracy. On the other
hand I don't ever recall a frequency spectrum analyzer ever being used to
determine judging points at a car show. It may be there was no
determination at the factory. I'm not saying it is wrong to strive for
accuracy, only that it might not matter. I hope you do find an accurate
answer. If so please report back because now I'm just curious.
This subject does make me wonder if the infamous "Road Runner" horn(s)
were of different frequency or they just had a slight, overlapping delay of
the same frequency.
