I wanted a 22hz subwoofer for my livingroom. After meeting with the budget/aesthetics committee, my wife agreed I could build a subwoofer that would serve as an end table and look like a trunk.
Step 1: Disclaimer
I am by no means a professional and I based my entire process on reading other instrucables and spending time on forums. I learned a lot through the process and would change a few things if and when I do it again.
Step 2: Hardware
Steps 1 and 2 go hand in hand. You need to decide what kind of performance you want combined with how much space you're willing to utilize. I decided to start with performance first and size second so I chose my hardware before settling on a design.
Step 3: Design
Come up with a plan for your subwoofer before purchasing building materials. I used a free program called winISD to help calculate my design based on the driver and performance I wanted.
Step 4: Materials
Using your design calculate how much material you need. I build mine out of 3/4 MDF, everyone online recommended 1/2 or 3/4, I chose 3/4 to play it safe.
Step 5: Cut and Assembly
If you're confident with your measurements you can cut all your pieces then assemble or you can cut and assemble as you go.
Step 6: Break-in
After assembling the enclosure I decided to install the driver and amp and let it run overnight using sweep tones to break-in the driver.
Step 7: Paint
I decided to paint all the areas that wouldn't be covered in leather.
Step 8: Wrapped in Leather
Began wrapping in leather. Attached leather with contact cement.
Step 9: Accents
Added hardware accents to make it look like a trunk.
Step 10: Finish and Enjoy
After the paint was dried I finished assembling everything, and began shaking the house.
