More CC vs RC questions was RE: Killer Octave & Pitch Raise

[David Love]

Actually, I think the RC&S board doesn't seem to require as bright a
hammer because the panel is less stiff (not the assembly, but the panel)
and therefore the impedance characteristics are different.  I'm not sure
that a softer hammer will produce "sparkly highs" it's just that it
doesn't take so much of a hard hammer to get the volume out of the
instrument.  That fact that the hammer is softer may, in fact, reduce
the sparkly highs as a softer hammer tends to damp higher partials, and
produce the impression of a narrower or more focused tonal spectrum for
the same volume.  Is that not possible?

Regarding your second question...  If the RC/S board doesn't require as 
bright a hammer to produce sparkly highs, perhaps the voicing technician
has 
more latitude to voice the hammer to emphasize the fundamentals.  The
result 
of the RC/S design may well be a richer sound spectrum.  Of course that 
would be my apriori assumption about any design that is more efficient.
In 
answer to your question, I suspect an RC/S board would be more capable
of 
producing whatever tonal qualities the voicing technician wished to
achieve, 
whether it is a darker sound (stronger fund. and weak overtones) or a 
brighter sound (weak fund. and strong overtones).  My point was/is that
the 
more rapid changes in spectral content throughout a note's sustain on a
CC 
board might result in a desirable expressive quality to that design.


Peace,
Sarah
