If you are having those resonances then there
is a problem.

#1, the smaller tube contained within the
larger, 2inch diameter pipe is CRITICAL
and should be the dimensions I specified.

The length of the little pipe is also

Additionally, the 2 inch opening in the
sphere must use a speaker no larger than
1 inch and there absolutely MUST be air
flow around the edges of the speaker and
the little speaker should be recessed within
the sphere by about 1/8 to 1/4 inch.

I typically have the plunger nearly ALL the
way out of the metal pipe affixed vertically
to the sphere.
