loudspeaker fibreglass

[bottleneck]

Hi All.

Long- time no post :)

Hope you're all well.

I made my TAD copies a few years ago, and have been enjoying them since.

I've had them open a few times, and played with the wadding materials.

I'd like to try replacing the long-haired-wool with the traditional JBL / TAD ''fibreglass'' wadding.

I'm a little (more than a little) concerned about breathing the fibres, so would like to 'coat' the wadding with somethign like glue to keep the fibres where I want them :) .. any advice on this aspect appreciated also.



.....Anyway... in the UK, generally you don't get fibreglass for this purpose any more. I don't know why. Usual stores (anything hifi related) just doesn't sell fibreglass for loudspeaker damping.

I have found the link below, and they seem to sell fibreglass of different types for reasonable prices.

I wondered if someone who is very familiar with the type of fibreglass wadding used by JBL / TAD etc would help me 'shop' for the right product?

They sell a lot of stuff, and I want of course to get the closest thing.


Here's the E-store -

The particular page the link takes you to is what I am guessing is the closest thing, but I've never seen the real-deal, so I'm poking around in the dark.


Thanks guys.
Cheers :)

I personally don't like using fiberglass wool because of how it desintegrates. I prefer using foam sheets, 2" thick. More expensive though.

Hi Chris,

Hairspray-lots of it seals the fibres.
I used Wicks cold water tank kitsWickes - Cold Water Tank Jacket customer reviews - product reviews - read top consumer ratings (http://reviews.wickes.co.uk/9987-en_gb/210205/reviews.htm)-unbagged it fluffs out to about 2" thick then used a staple gun to pin it to the enclosure.
This close stapling ends up with a layer that's about 1-2" thick.

Hello Chris

That is the wrong type of fiberglass. That type is structural used in boat hull construction as an example you want essentially fiberglass insulation like used for home construction.

Here is a product that is made of recycled denim that can be used instead of fiberglass. http://reviews.homedepot.com/1999/202709974/16-in-x-48-in-ultratouch-denim-insulation-multi-purpose-roll-reviews/reviews.htm
