My Test mule and car subwoofer
Hello,
I built a subwoofer with my brother a few weeks ago using some left over parts from other equipment.
The Amplifier was from an old sealed subwoofer I had kicking around with a blown driver, and the Driver came from a friend that didn't want it (Very cheap car subwoofer driver, under $30 retail). As you can see, the final product wasn't expected to be that glorious.
The box is constructed of Birch plywood, with 0 bracing and stuffing. We basically used this subwoofer to measure our building skills before I try to build my Kappa Perfect DIY (when ever I start that). We determined that you actually need to measure the cut out for the driver, instead of guessing (no compass).
A couple problems came up with the driver seal, as the metal frame around it was bent, so I needed to be straightened (hammer time!). It also didn't have the gasket to go along with it, so I put some caulking around the edge to "seal" the deal.
Here is what we came up with.
Awful, just awful. It doesn't sound as bad as it looks, but it still blows. Good attack, thats about all I have to say.
My car subwoofer is sitting right on top of it. It consists of a JL W1V2 10 inch driver in a slot ported JL made box. It has a 200Watt clarion amp (oo, fancy) and I used an old 420watt PC PSU to convert my outlet to DC. The PSU didn't have quite enough juice to deal with the dynamics in movies at my listening volumes though, and it would regularly run out of steam. However, this subwoofer is going in a tiny civic hatchback, so it should be loud enough in there.
I run the DIY cheap sub with my DPS-12 right now for the more uniform bass, and fun factor. The attack from the unit really adds to movie watching. I also like it when I play along with my stereo with my guitar.
