Being an engineer, I can calculate proper cubic feet for a box, but I don't have the time to tweak something to tune it. I'd love to find some plans. So who here has built a sub that will get down deep enough to rumble the neighborhood and play steadily up to all the necessary octaves that a good sub can produce? Total budget being the same cost as the HSUs which is less than 1800$ for the pair not including the finishing material... I got that sitting around.
Do yourself a favor and spend a little time researching what you can do with DIY. You'll be glad you did.
I was in the exact same boat as you last summer (hey, I'm even an engineer
) I was looking at getting a couple of HSU's and stumbled in here. I was overwhelmed at first, but kept reading. Pretty soon I started to grasp on the common things that need to be done to build a sub; the popular drivers being used (and why), an external amp, ported vs sealed and the benefits of each, different box designs, etc. I read, asked questions, and learned a lot from the great folks here. It wasn't long before I was ready to go.
I went the easy way first (and I'm still enjoying it); a pair of 18" UM18 drivers bundled with pre-cut sealed kits. No cutting was required, just glueing/clamping and then finishing.
I got two 18" subs for $424 each, plus $349 for the amp; total of $1200. They're fantastic and put a smile on my face every time I watch something. If you're willing to spend a little time and effort, there's no better bang-for-the-buck.
Of course, those were just "gateway speakers" and now I've added DIY speakers for LCR and surrounds (5 total), plus nearfield subs. But that's another story....
