Intro: 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 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) 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!
