Slot-Ported Mini Subwoofer

In this instructable (my first) I will show you how to make a mini portable Slot-ported Subwoofer!
Please leave comments - be critical but nice as this is my first instructable and I am only fifteen.

IF YOU CHOOSE TO MAKE THIS I WOULD LOVE TO SEE PICTURES, Thanks

Step 1: Ingredients - What You'll Need

First of all and obviously:
>A Speaker
>Some Cardboard
>Tape
>Craft Knife

Secondly:
>A small amplifier, i have a tiny amp (shown) which suprisingly is capable of supplying enough power for the Peerless 3.5" 60w woofer I used.
>Wire, any will do, I used standard black and red audio cable.
>Some decent tunes to knock through the finished speaker!

Step 2: The Pieces

You'll need to mark out the pieces of cardboard to fit your speaker and you preference.
Here i went for:
(1) 20x30cm
(1) 20x27cm
(2) 20x15cm
(2) 15x30cm
and
(1) 12x20cm (for Bass Port)

Step 3: Cut! Cut! Cut!

Now for the tricky bit. Cut out all the pieces. I have injured myself very badly from various craft knives and therefore asked an understanding adult, in this case my dad, to help.

Step 4: Try It Out

Now you need to lay out the pieces in the way you are going to stitch them together. or glue. or tape. LOL

Step 5: More Cutting

cut out the hole for the driver in this case
Diameter of cutout = 92mm

Step 6: Tape It Up

now you need to fix all the joints between the pieces and affix the driver. i went for bolts!

Step 7: Now to Seal It

Tape it up so that it is sealed and ready for use. Don't forget to wire it (thats what I did) duh :)

Step 8: Nearly There

Almost done now. I fed the audio cable through the port thus illiminating the need for another hole to be made.

Step 9: Plug in and Rock

Find an amplifier and a source of music. its plug in and play!
