I am new to building ported boxes and have learned a lot just reading the stickies in this forum. It seems that most box designs in the "Free Box Plans" post are for one or two woofers. I also read the "Simple EDU: How to Design a Ported Box" post which was very informative but also seemed like it was aimed at single woofer design.
I was wondering if anyone had experience with building a box for more than 2 woofers. My only limiting factor in box design is width. I have about 3.5, maybe 4ft. I would rather not build 3 separate boxes but if I have to, I will.
