HOW TO – Folding speaker enclosures

Rick shows you how to make your own speaker enclosures from paper/cardboard, he writes – “…the box is an 80mm cube but it could be any size you like just choose the card thickness to suite the size of the box. Although this was made from card you could just as well use polypropylene as a harder wearing material, you can often buy stationary folders made from polypropylene that you can recycle.” – Link.
