Hello everyone, I would like to build my first ever sub or speaker, but I'm starting from scratch. I've read numerous threads on the subject, but like I say, I'm starting from scratch and need to educate myself as much as possible on the subject before I can successfully design the sub. First, can someone link me to a place to explain what all of the parameters mean? I will mainly be basing this sub on someone else's successful plans since this is the first, but would like to understand the terminology used in WinISD to possibly tweak a future design to my liking. I picked up The Loudspeaker Design Cookbook for future use(would like to build some speakers at some point too), but it's just over my head right now. I don't plan to learn this stuff overnight, but I've got time, so any advice is welcomed! Love this site and thanks in advance!
