First post on the forum here goes:

Just bought an old RCL 1290 12" driver off ebay with the following specs:
90 watts, 8 ohms, Res 35Hz, SPL 95 dB



i started calculating the Vas for building box and reliased that i didnt have data for the compliance of the speaker.
Does anyone out there have the relevant data or know how to calculate the Vas from the data already given, i.e. similar data on another driver?
The driver was pulled from an old bass amp but i cant find any information on the internet.

any help?

cheers,
Richard

p.s. heres a pic of the driver:
