I considered the PB12 once (but took the SB12).

This is all I could find on my HD:

VAS 160 litre
Qts 0.30
Qes 0.32
Fs 21 Hz
Xmax 14 mm

This is an old thread but I was looking for the specs on the Lambda PB12.
Seems these lines from above indicate this is the 10" PB10:
Part# PB10 Cms 0.4 mm/N
Size 10" Mms 143 grams
Actually all the other numbers look about right for a 12" driver so
perhaps the 10" figure is just a typo.

Also looking for the SAE 1204 specs ... anyone?
