El-Pipe-O (El-Pipe-Mino) ???

[Ernesto]

Hi Nelson and others
Could anyone tell me what length of 12" sonotube I would need to build an El Pipo with my Shiva Mark IV? If I understand correctly, since Shiva has an Fs of about 21Hz, I would need a 13 foot long pipe to be at 1/4 wavelength. I have already built a stereo pair of T-lines shown below, but they are only about 7 feet long. Can anyone tell me how to calculate what the response should be with that length?
Thanks
Chris

Hi CPORADA you can find the best info at this site :

altought there are many other good sites about the topic.
Put tline audio design in google or yahoo and you have a bit.

Hark? Is that an earthquake I hear, or is it just your new subwoofers shaking the foundations? 😀
