After asking for designs from other peeps on other forums and getting nothing I've been fortunate enough to find this forum and the free box plans. I'm thinking about building a box as per one of the free designs now...don't know how it will sound but I'm a bit curious. So...I see a lot of different designs but I'm wondering if the design has one sub does it have to be one sub or can i mount 2 subs and same for the designs that have no subs illustrated? Second how important is the exact placement of the sub cause most of the designs don't exactly have where it should be mounted?
