My intention is for this instructable to be more of an inspirational guide rather than a strict series of steps. Of course I'll give the basic steps that it took for me to build mine, but with projects like speakers, a lot of variation is possible. I want to give you as much freedom of creativity as possible.
This Instructable is to build ONE SPEAKER. For a pair, simply repeat the process. I would recommend reading through the entire instructable before starting. The instructable is going to be split into three main parts: The Enclosure, The Circuitry, and The Assembly.
Another awesome instructable for speaker building can be found here:
This is my first instructable, so any and all feedback would be extremely helpful and appreciated.
If you have any questions at all, feel free to message me and I'll do my best to help.
Step 1: What You'll Need
Dremel and Bits
Power Drill and Bits
Ruler (T-square works)
Scoring Pen (T-squares usually have one hidden inside)
Soldering Iron & Solder
For the Enclosure (Note, sizes vary depending on what drivers you choose):
3/4"x3/4" Pine Beams
1/4" Oak Wood Boards
1/4" Acrylic sheets (I used Lexan�)
6 Angle Braces & wood screws
8 Bolts and Lock Nuts
6 Furniture Pads
For the Circuitry:
16 LEDs (I used two groups of 8 LEDs each, but you can mix colors if you want!)
2 NPN Transistors (I used 2n4401)
1 Speaker terminal
Insulated wire, 3' per speaker should be fine, but it'll vary depending on how big your speakers are
Speaker wire (12 gauge should be fine)
*Various wire coils
*Various polypropylene capacitors
*Various low-inductance resistors
*These parts are for the Cross-Over (Which separates the high and low frequencies of the audio), the L-Pad (which adjusts the volume of each individual speaker), and the Series-Notch Filter (Which controls the peaks at the resonant frequency of the drivers). Alternatively, you can just buy a pre-made one (which as it turns out, is usually cheaper).
