To: "Maddog 'n' Miracles" Subject: Re: More Resonant Speaker Stuff [snip] 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 CRITICAL. 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.
