    The wool and synthetic sheet is going to be used to damp standing waves rather than pack cabinets. Wool is rather good used for this purpose. I had it's ability demonstrated to me very persuasively.

    If you are experimenting, you may find that IKEA bed comforter/quilts may be a cheap and efficient alternative!

    I use carding combs to tease out the wool.https://encrypted-tbn3.google.com/im...A2nWgXM-rupNrQ

    Following my homebuilt speaker purchase and reading this thread, i was hoping to do it on the cheap and purchased some cheap felt mat from ebay,
    received the item today and it's rubbish, so i'd like to warn anybody looking to do it on the cheap steer clear of this stuff,
    it just feel like stuffing swept up from factory floor and put through a press to condense it together, needless to say it fell apart in my hands,
    moral of the story is listen to Geoff and buy the right stuff.

    Looks very similar to the stuff used on the inside of the Yamaha NS1000M monitor, along with other damping material

    Though it certainly doesn't fall to bits in your hands

    Mark,looked good in the listing and spec sounded good but a nightmare to work with, it ripped when i unfolded it, should have got this stuff instead.

    Cold water tank insulation kit from Wicks about a fiver.
    2" Fibre glass but when sprayed with hairspray it's fine.
    Good enough for JBL, good enough for me!

    Frank,

    I will take that onboard thanks, it'll come in handy if and when i get my big speaker build project running (GPA 604-8H-III),
    always like your post on big speaker builds whenever i come across them and i am a big speaker fan.

    Hi Andy,

    I am also a fan of Duvet damping, it comes already covered in white cotton so is really easy to staple into enclosures and again you can line a pair of large enclosures for under a tenner and in under 10 minutes.
