Power compression is a topic that is rarely discussed, but always important. When you hear someone call various theile/small parameters a “small signal parameter”, the implication is that with larger signals (more power), there will be a shift or change in these theile/small parameters. This is what we call power compression, and occurs in 3 potential ways.
It's been a while since I've put anything meaningful together, so it's time for another fun technical article!
Excursion is a large contributor to high output in any driver on the market. Typically, larger excursion (seen visually as how far the cone moves in and out) means more sonic output. However, with excursion come challenges.
this particular how to is designed to teach you the basics of designing an enclosure for your subwoofer. a lot has changed in the last decade and computer simulation has made things much easier to predict how a speaker will perform in a given enclosure. there are a wide variety of programs out there that come highly recommended. for this how-to, i will show you how to use my favourite free program called UniBox.
