|Lately I've observed closely a behavior of 3Ē
general purpose unit (TV sets, multimedia speakers).
There was a substantial bump in frequency response from
2-3 kHz. Iíve calculated wave lenghts of this region
and found out that they corespond with radiuses of
driverís surround. Just to prove my assumptions are
correct, Iíve applied strips of insulating tape to
smooth transition between a cone and surround.
Measurements showed that this tweak works.
This modification is very crude, but
when done nicely, it could provide even better results.
