The citation without the referenced material isn't very illuminating.

Actually the material I've read online along with the calculators says that they are calculating the length of the primary tubes and the length of the collectors so that the negative pressure generated from the soundwave leaving the primary tube returns to and continues through the ideal timespan at the same cylinder that it came out of and they ignor the other cylinders because the % of the negative pressure that enters the other primary tubes is negligable.

OK Mike, if you are not interested in learning, then I can't help you. I'll leave you with the 'bent iron technology'.

Cheers Harvey.
