Problem: Harsh tops
interviewed by Peter Strassacker (7/2004)
Gerd, please tell us, after designing or buying a loudspeaker that reproduces
harsh tops, what can be done?
There are two possible causes:
1) the tweeter is to loud Remedy: Fitting a voltage divider before the tweeter
for level attenuation. (I have an Excel file to determine resistance values,
a fixed table for 4, 6 and 8 Ohm is also OK).
We've got a Calculator too.
2) The tweeter sounds harsh and aggressive (rather in the lower frequency
range of the tweeter) Remedy: Reduce the value of the capacitor before the
tweeter by 20 - 30% (when using a 18dB/octave filter the first capacitor).
Thanks very much, Gerd.
