Coaxial Speaker Cabinet




Introduction: Coaxial Speaker Cabinet

Hi everyone,

This intractable is to show you how to make a decent speaker using a coaxial speaker cone. When all is said and done, the audio source will be an aux cable and the box will have an on/off power switch.

Step 1: Components

What you will need in order to build your cabinet is:
A coaxial speaker
6w amplifier
Any length AUX Cable
24 volt DC power supply
Rocker switch
Plate to mount switch

6 sq. ft. of MDF (You can use any wood you want)

1 inch screws

Soldering iron
Mini flathead screwdriver

CNC Router

Step 2: The Guts

The inner wiring for this speaker is pretty simple.

1. Begin by soldering the ends of all of your wires (for better connection)

2. The wiring runs as such:

Your standard speaker wires run from the speaker the output portion of the pre-amp. Red is positive, Black is ground.

The power source runs to the power slot. Depending on the source you use, it will tell you which wire to lead with. This is very important. For mine, the white striped wire was positive, and the back was ground.

The aux cable runs to the input slot. The thicker wire is ground, while the red and black wires go into the positive slot, together.

Power source wiring

The power source must run through the switch. So, depending on the power switch that you use, the wires will run through it differently. On mine, the white striped wire ran through the middle, and continued through the bottom slot. Make sure to solder them on well so they don't break off.

Step 3: Cutting the Body

For the good majority of this step, you can improvise. YOu can make the cabinet however large you want, but I made mine 10" x 10" x 7". I used 1/2 inch MDF wood. It is easiest and most precise to cut.

When designing your box, be sure you have a hole for the speaker that's 7 inches in diameter. The hole for the power switch that I used was roughly an inch. And, the hole for the aux chord was 1/2 an inch. Also be sure to have an outage for your power source in the back.

Step 4: Assembly

As far as assembly, don't forget to drill your pilot holes, so you don't split the wood. Make sure the speaker is fully secured so that it sounds better.

Once you have the Face and 2 sides screwed together, leave the back and top open, so you can arrange all the wires on the inside.

I used a small piece of velcro to mount the amp to one of the sides, and a piece of gaffers tape to coil up excess cables.

Aside from those tips, make sure to wire everything in tightly, so that nothing falls out.

After everything is wired, you can close it up. Make sure the power brick is OUTSIDE the box.

For the bottom of the box, I used a sheet of cardboard instead of wood, so it doesn't scratch and it is easier to access in case anything inside is bad.

Step 5: Enjoy!

Once you've done some polishing (to your liking), the speaker should be good to go. Make sure to test it out before sealing it up completely.

Happy listening!

    Nice project. I see you didn't predrill your screw holes because you did split the MDF. And MDF splits very easily when using screws. Another idea if you want to forgo the screws is to use Gorilla Glue. It is moisture cured and amazing holding power with MDF. If you do seal the bottom and all openings, then the bass will increase being an acoustic suspended type setup. Just some ideas.

    Thanks for the feedback! I'm fairly inexperienced when it comes to woodwork and any tips help

    Didn't you just take a speaker apart and put it back together again???

    Cool DIY speaker build. I love custom speaker cabinets because that is the only way that they will fit in a lot of places.
