Quite but this sounds good on the PC speakers 
which die below 90HZ, where as my Hi Fi speakers 
are flat down to 16HZ.
I suspect a lot of the hype about big bells is 
about the acoustics of the way they are 
installed.
Perhaps they should be installed above an open 
tower like the tubes of A Xylophone, to boost 
the lowest frequency and compensate for the 
falling off of the diurnal curve, rebalancing 
the sound, or the perception of it.
I must get down to pitch bending the a recording 
of a really good bell, down and down, and 
boosting the lowest note with a graphic 
equalizer.
I suspect the "simulation" of a HUGH bell over a 
resonator will be rather impressive!

(I have a development pair of IMF TLS80 
speakers, with the actual acoustic plots, so yes 
they really do work, they are nearly 4' high and 
2' square)

I like the sound of this bell (Peter bell at 
Cologne).

Hopefully the Olympic bell will sound as 
impressive as this.

Listen right to the end!

Ooops,

Matthew

Harmonics are multiples some at octave intervals 
ABOVE the fundamental.
What is the predicted fundamental for this bell?

For comparison, a 64ft organ stop goes down to 
16 Hz which is audible,
although 13Hz is not.
I was present at a demonstration where a sound 
meter was switched on and
read 100dB although nothing was audible not even 
as a felt vibration, I
think that was 10Hz

It may well not be tuned. According to Bill 
Hibbert, there is little
point in tuning bells of this size as most of 
the harmonics are too low
to be heard.
