Fellow enthusiasts.
I require your input if you will.
I was lifting stubborn dust from the paper of my inner speaker.
I grew impatient and I wiped a small area with a lightly dampened cloth.
A weak spot I now have in my speaker. :dunce:
Its not awful but I know my box can take more bass without farting.
I'm thinking of using a paper mache, a light paper dowsed in water and glue applied to the back of the weak spot.
Hopefully after it dries this will strengthen the area.
what do you think?

Cheers OSS :afro:

I think you should NOT use paper mache to do this because the extra weight will increase the mass considerably and affect the sound quality. If you wish, you can cut a small patch of something thin/light. Tyvek is great since it's light and incredibly strong. Paper may work but it's hard to find a strong/thin combination. If using tyvek, attach it using contact cement according to the instructins. If using paper, elmers or wood glue is best. This recommendation is only for strengthening the weak area.

If your goal is to increase the stiffness of the speakers so it does not fart, you can paint it in several layers with a slightly thinned wood glue mixture. Guitar amp box users have done this successfully but just keep in mind that guitar amps aren't required to reproduce the full audio spectrum. I've also heard folks use Krylon paint to add cone mass to prevent the farting. Just remember that adding mass and stiffening the cone, while it does tend the strengthen the low end, trashes the efficiency of the speaker and reduces the highs. Also, if doing this, only do the cones and not the dust cap and/or surround.

Scott, you need to find you a good, semi-stiff 2" paint brush to take care of dust and dirt.
