[QUOTE="n2audio, post: 8306514, member: 540940"] Building a standard rectangular ported box requires only a basic knowledge of wood working. If you can cut reasonably straight with a circular saw, cut a decent circle with a jig saw, and run a drill you can build a ported box (access to a router is a plus as well). The technical step is coming up with a good design. "Tuned to x hz" is a standard reference to the basic features of a ported box. The box size and port size interact to produce a particular tuned frequency. Box modeling software helps organize the many different variables involved to arrive at a box size, port size and associated tuning frequency that works well with a particular sub in a particular application. Yes, I saw that recommendation as well. But the mfg doesn't always recommend the BEST enclosure. They often go with the simplest enclosure that will "work". Yesterday I looked at several different sources for driver data but just now I came across a thorough set. I'll plug them into winISD (modeling software) and let you know what it comes up with.
