cF = cubic feet
Hz = hertz (frequency)
Sd = surface area
xmax = maximum linear excursion
xmag = maximum excursion
dB = decibels

you should be able to pick these things up quickly, just browse the forum reading stuff...thats what i did when i started :-)

Xmag=excursion limit based on magnetic limitations
of a specific drivers motor.
Xsus=excursion limit based on suspension limitations
of a specific driver.
Xmax=smaller number of xmag and xsus.

just google "t/s parameters"
youll learn a lot.
