bwaahaahaa!

Ok, the details.

for highs I use edgel corn Kernel 100g tins with 0.8mm wire. They sounded a bit harsh so I put a small bit of cotton wool and blu-tac inside.
For mids I got a bargain pair of 385g beetroot slices and 1.8mm nylon twine. they give a nice strong midrange without being overwhelming.
Now the bass is faithfully reproduced by a trio of 3 litre tropical punch fruit juice. They are roped together and signal is supplied by 4.8mm hemp rope. It's a little bit light but I hope to upgrade to an eight pack of pineapple juice for some deep tight bass.

I dont have installation pix yet but I can work on it if you like.
