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

It is a high xmax, stiff poly cone with stiff poly dustcap, coated and sealed foam surround, 12 spoke aluminum basket, dual stack 120oz magnet, gold binding post, military spec coatings and glues. It is a high excursion, very low distortion, super tight bass driver. Recommended maximum crossover point is 500Hz, rated power handling is 500W. Available in 4 or 8 ohm.

*Below are specs for 8ohm model, for 4ohm model;

DCR = 3.5 ohms, 2.83VSPL = 91.6dB

Recommended cabinet of 2.0~4.0 cubic feet vented or passive radiator

Fs 21.0 Hz
Qms 4.2
Qes 0.32
Qts 0.30
Vas 160 Liters

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?
