How to build a  quick, easy and cheap loudspeakerbox with drainpipe material
Hi everybody

This is a very short and universal instructable to build an easy and cheap loudspeakerbox. It works with a simple trick and is quickly done in three steps.
I need such boxes for my next steampunk instructable working with two old fashioned brass horns. I will post this later;-)))


Look at the small video first how it works and then I'd like to explain the different steps with detailed pictures.



Hope you enjoy this new instructable.

Step 1: What do you need

Only three parts are neccessary for this box. First an old loudspeaker from an old pc (0,-Euros), then a HT drainpipe muffle (also called double socket) DN50 mm (about 1,50 Euros) and at least a drainpipe blind plug for DN50 mm (about 0,50 Euros). The drainpipe parts can be bouhght at every homeimprovement store.

Look at the dimensions and you will see that all parts fit perfectly together.

Step 2: Prepare the box

To prepare the box you have to cut the muffle right in the middle. First fix the hose clamp and then cut the socket with afin saw.
Next yo have to remove the rubber gasket. It works best with by using a screwdriver.

Step 3: Put in the loudspeaker

To put the loudspeaker into the gasket ring of the drainpipe socket, place it into a bench vise. Press now the pipe slowly a little bit together until the loudspeaker starts to move in. Then take the socket out of the vise. Now press the loudspeaker carefully and softly with your thumbs in. It works very easy and you will hear a "Snap". And that is it.

Step 4: Close the box

At last you have to replace the rubber gasket. You can do it from the front- or backside of the speaker. If you choose the frontside you can put a horn later on (eg.made of paper, plastic or metal) and generate the effect of a real pressure chamber horn which means that the loudness will rise. It works like an amplifiying horn of a grammophone.
Now you have to drill a hole at the socket side or through the cap to put the speakerwires through. Close this hole with melting glue tight.
After this you close the loudspeakerbox by plugging the cap in and your work is finished.
