Hey all, I'm wanting to try my hand at a DIY sub. My budget is around $500. The room is roughly 12 feet by 16 feet, 8 foot ceilings.

I've not build a speaker or a sub before, so where should I start?

You should start here, as this is where the (subwoofer) crazys live.

The easy starting point is:
http://www.parts-express.com/pe/showdetl.cfm?partnumber=295-514
http://www.parts-express.com/pe/showdetl.cfm?partnumber=301-512
http://www.diysoundgroup.com/subwoofer-flatpacks-2/3-sub-flat-pack.html

$170 + $200 + $90 + glue paint, wire, terminals, fill ~=$500

This is as simple as it gets. Knock-down box that you assemble. Driver's a drop-in but you will have to cut a hole for the plate amp. A drill, jigsaw and screwdriver are all the tools you'd need, plus glue and paint/sandpaper. I've made diysoundgroup's boxes before; excellent quality - duct tape is all you need to clamp them while the glue dries. This driver is new but very capable, and at a good price. Chose the amp by price too, on sale this month and well suited to this driver.

With a 3 cu ft box, F3 is 32Hz and F10 ~20Hz. In your size room, the lowest supported mode is 35Hz (16 ft. half wavelength), so you're well into room gain by the time the sub starts rolling off. Should be a good match without using any active boost.

Just be aware that there are a dozen "good matches" to your request... this is only one.

Have fun,
Frank

The only problem with this ^^^^ is that you will likely soon decide that you need to upgrade the rest of your speakers to keep up with what the sub can do. I'm not saying that is a bad thing....but you have been warned wink.gif

depending on the size of the room, you may need some low end eq that the yung amp does not have.

Listen. It's All Good.
