Yep, that way is wrong.
If you really want to learn more about quarter wave theory, http://www.quarter-wave.com and http://www.t-linespeakers.org are a much better sources for information.

for sure. i read those when i first started being interested in tls. they were way to confusing. then i stumbled on this other site which seemed alot less confusing. but now that im started to get it alittle more maybe i will go back to the "real tl sites" good looking out
