I have an old EPI 6" woofer that I'm looking at and putting it on my
function generator, the speaker distorts badly from around 40hz to 120hz but
fine at all freqs above and below.
I've never really indulged into the world of woofer construction and repair
other than knowing the basic principles.
There is no surround problem....there is a very small pinhole in the cone I
could fix....but what exactly is going on when a woofer won't perform at a
specific band of frequencies like that?
It will break up between 40 and 120 hz and also when I "move it" manually
between a certain range in it's travel.
There doesn't seem to be any impairment of the cone at all....nice and
smooth in when I move it back and forth.
And it breaks up straight out of the function generator so
it's not getting much power.
