1. What is a pre-compensation load? Is it the same as the R2 on a L-Pad (R1/R2)?

2. Is it possible to have a pre-compensation without the main R1 attenuation? Or is it just a reactance adjustment for the motor? (in some PA speakers I have no R1 and a R2=16.5 Ohms in shunt with the motor / X-over C=3.3uF series and I=0.72mH shunt / What x-over freq. is this and how to find if HF/Motor is of 8 Ohm impedance?)

3. Are the designs you show for L-Pads correct, since they do not show the same connections as for other (standard) L-Pads? As an example from pag.60 a 12dB attenuation R1=25, R2=16, C1=0.47 and from pag.63 a 14dB attenuation R1=30, R2=14, C1=0.33.
I am used to see R2 in shunt with the Motor and "after" R1. As an example from another site: http://www.lalena.com/audio/calculator/lpad/
For an LPad (Driver Attenuation Circuit) with Att=-12 db and Z=8 Ohms => Resistors
R1 = 5.99 Ohms
R2 = 2.68 Ohms
Or for an LPad with Att=-14 db and Z=8 Ohms => Resistors
R1 = 6.4 Ohms
R2 = 1.99 Ohms

How can your design deliver 10.8 Ohm in the HF/Motor side on the first case and 10.2 Ohms on the HF/Motor side of the X-over for the second case? Is this right? Are the BIG resistor values you use better -- as in table of page 23 -- than say the small values for 'other' L-Pads as in Lalena.com. What is the difference, are they of the same effect after all?

Congratulations and Happy New Year.
