The speaker design I am building calls for a “Dacron Type 9oz” dampening material, which looks to be about 15mm thick on the drawing.
Can anyone advise me what the equivalent would be in the USA for this?
From my Googling and calculations, this is a medium loft Dacron batting with a 1 oz per sq ft density. I.e. 9oz = 305 gsm = 1 oz/sqft.
Is this the correct equivalent to what is spec’d?
