preliminary dual 18 manifold

[scameron78]

i've been messing with this design, which is an 18sound design, using peavey low riders. i figured the box as a ported enclosure, 13 cuft tuned to 35hz. the box most likely will have to grow because i haven't taken into account my bracing. but anyways, i've read a thread that djk posted a reply about how he designs his manifolds. i like the push-pull concept.
