Request: Peerless driver specs

Can't seem to find any specs or references to a Peerless driver.

Catalog number: 831864, 8", poly cone, stamped metal basket, 4 ohm

Looks like an old CSX to me...

Any help appreciated.

Don't light that cigar just yet.


Even though WinISD has the driver listed, it seems to have too few params to calc the port dimensions.

I transferred the params to LspCAD but as per usual, it says "too few parameters defined". Even using the crosscalc feature doesn't help.

Anyone know how to work out the qes/qms from the given data, which is, at the bare minimum, what WinISD needs. I just need a good working box volume and port data.
