To: "Maddog 'n' Miracles" Subject: Re: More Resonant Speaker Stuff I have detailed information on possible lengths if you change the smaller tube diameter. Hopefully I can find my hardcopy. Smaller 1 inch speakers are found in some external modems and as microphones for some older telephones. Also, Radioshack sells a 200 mW version that works great but blows out if you aren't careful around strong signals. There is a critical association between the sphere volume, sphere hole opening diameter, and the speaker diameter. I'll get back to you on the inner-tube changes. -Ed Loranger WE6W -- 72/Ed we6w; A-1 OP; SOC#63; QRPL#1068 http://www.qsl.net/we6w Santa Rosa, CA My 2 pennies worth is just common cents.
