which is which

which of the old 3 slug options were cosidered basically universal, D1 or D2.

i bought my btl from teampsi on ca.com, on his ad he said its a D1 so its basically universal. i have read else where that the D2 were the ones considered universal.

can anyone clear this up? im about to order a recone, and i want D2's but i want to make sure it will fit!

thanks fellas

Universal: This option gives you the choice to later chance the impedence of your voice coils. You can change from dual 2

Unless it's a very old sub...then odds are we can probably do something.

Do you know for a fact that it is a D1 motor?

heres the link to the original sale, team psi at ca.com says it was a D1 motor

is there a way to identify a D2 from a D1, other than measurements? which i can check:)

Do you have a pair of calipers? You could measure the gap and then Fi can tell you what they can do for you. . .

DMM to check..

bassahaulic it was a D1 before i took the cone off, and i will be measuring the gap at work today with a faro arm (3D mapping and precision measuring instrument)

its damned hard to measure a magnetic gap with metal calipers:D
