I bought from ebay so im not worried about my dosh
And if they're packaged like the ones I bought, they put little plastic spacers between them too.
its more the fact that i dont want to wait a gorrilion years
kek
Shouldn't have ordered from China then.
You've fucked up.
i mean in addition to the time already
i dont need the magnets yet anyway
ive still gota get the fibreglass substrate and work on the diaphragm
finding thin aluminium will be a pain in the ass
How thin are we talking?
http://i.4cdn.org/g/1487392420686.webm
like around 30 micron
but its gotta be at least 70mm x 70mm
That is quite thin.
Can't help you there.
yeah
No luck sourcing it from China?
planar diaphragms gotta be thin
not yet
though i havent been looking for long
im already using 20 micron kapton film for the actual membrane part
the aluminium is just the trace
and ill etch with ferric chloride
Found a 2 ton roll for $2500 for you.
huh this might be good

Nice. ~Twice as much as you need. Seems quite cheap too.
i mean its aluminium foil
itd be cheap no matter what
unless it was like >5 micron or some crazy level of thin
shipping might be the real killer tho
havent used alibaba before so eh
how the fuck do i find shipping price lol
I guess you have to actually work that out with the supplier.
eugh
or use a taobao middleman
like taobaoring
do taobao middlemen also do alibaba?
