so i was talking to the local speaker shop and he told me he has 4 ported 10s in his car and a girl with a single 12 was almost as loud...and he has installed losts of systems, he said his 4 tens were some of the loudest he did, but second was one 12!? he told me the box was made at a different shop and it had a chamber that broke off into a port that was zig zag. a big long box with a really big port at the end. do any of you know of a design like this? what is it called???!!! and how do i find plans for one?
yes i drew it in paint and thats what he drew in pencil, he said that was its layout and it had 1 12 pounding as hard at 4 10s
