I see a problem with those.
Let's look at a high pass plug-in filter using the math from my post, http://www.audioasylum.com/forums/tubediy/messages/22/229184.html
I believe the plug-in is just a cap in series followed by a resistor in shunt.
If the plug-in doesn't take into account the input impedance of the amp then the crossover frequency will be wrong because the shunt resistor is in parallel with the input impedance of the amp and Harrison has no way of knowing what the input impedance of your amp is.
I'm not saying they won't work, they just won't work at the stated frequency.
