| Lately I've observed closely a behavior of 3”
general purpose unit (TV sets, multimedia speakers).
There was a substantial bump in frequency response from
2-3 kHz. I’ve calculated wave lenghts of this region
and found out that they corespond with radiuses of
driver’s surround. Just to prove my assumptions are
correct, I’ve 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.
