Do these make sense to you?
# Re 7.6 (3.8 Ohms per coil)
# Fs 38 Hz
# Qms 5.10
# Qes .37
# Qts .34
# Mms 81g
# Sd 196 cm^2
# Vas 11.8 l
# SPL 84.5 1W/1m
# Bl 20 TM
# Xmax 16mm
# 250W RMS
This is an 8" driver. I came up with some pretty weird enclosure sizes for a QTC of .71 based on this. What do you think?

The EBP of that driver is 102. That makes it better-suited to a vented enclosure than sealed. In 0.28 ft^3 and a Fb of 42 Hz gives an F3 of 44 Hz. The required vent would be 1.5" diameter, 8" long.
It's a bit strange how the numbers work out. I wouldn't be surprised to find there's a spec typo or that it doesn't measure the way it's spec'd. Frustration over stuff like this is the biggest reason I learned how to test for myself.
