Acoustic damping 4pi speakers [message #87804]

I am very new to the world of self build speakers and this is my first post.

I am very slowly in the process of building 4 pi speakers, I'm in the uk and can get 100mm fibreglass insulation. However i wondered if there was a better product available. Mundorf Twaron angel hair/unicorn tail wadding?? 8mm felt or egg box foam. These are all available at a specialist hifi website over here. I have literally no idea about any of them. I would appreciate input. Or stick to the 100mm fibreglass.

Thanks in advance.

Use fiberglass insulation. I haven't found a better product for acoustic damping inside a loudspeaker, and I've sure found a lot worse. Occasionally someone will try a different product and get poor results, so they eventually rip it all out and go with R13.

Thank you for your prompt reply.

I will do so-it's a lot cheaper as well.

R13 doesn't exist over here. I presume 100mm fibreglass is the equivalent.
