5. Completed cabinet design .

1. First Step .


This is the chassis of and old 416 8Z woofer from Altec Lansing . When taking off the cone use a simple knife and add solvent to the glued parts . Those parts are very difficult to get rid off, however if you want a clean job you must take them away .

If youre using a new recone kit and youre not sure about the spider and voice coil original configuration , cut the spider around the landing so you can compare whith the new cone .

It is a very good idea to replace all screws and to separate the magnet of the chassis . Metal can get corrosion so screws may be in very bad shape . !! If this is the case and you cannot  unscrew them I use a simple Dremel tool to make the job .

Once you dissasemble the magnet have a look betwwen the poles, debris accumulate over the years. Little pieces of metal can be there , you must remove them before installing the new voice coil !!!

Just cut a piece of masking tape and bend it the way I did . That way you will clean both poles , make sure it is pressed until the bottom .

Lets see what we got here !! Very dirty poles . Use the tape until it come out clean .
Ive always like the flavour of the ALNICO magnets so its a nice idea to make them work again .








clean  After removing all dirt and sanding the chassis it is ready for paint, black is a good choice .

Ok , now they are ready to be reconed again . Always make sure you cover the magnets poles while working !!

Lets wait until fresh parts arrives ...
