Any use here for FIR filters? Which of the above are considered FIR or is that yet another type?

Follow Ups:
RePhase generates FIR filters."... rePhase is a free FIR generation tool for building fully linear-phase active crossovers with arbitrary slopes.
It also let you manually compensate for the phase shifts of your loudspeakers and existing crossovers, be it active or passive.
Once generated, the FIR can be applied using any hardware (openDRC, miniSHARC, Najda, ...) or software (foobar, convolver, JRiver, ...), stereo or multi-way convolution engine. ..."REW supposedly generates 2nd order biquads IIR filters that can be exported in XML format and then imported into RePhase to do frequency correction or you can make them by hand.

I've read thru some of those helps and the assumptions they make about a persons knowledge bas is way off my scale.
I need 'The Idiots Guide' version.......

There is a bit of learning curve for all of the software packages.
They contain a lot of features that you may never use all, but you can start out with some basics and then progress over time as desired.
If you are going to just time align subs with your mains, REW alone can be used to measure what is going on in your room using your receiver's or plate amp's delay functionality without ever having to make FIR filters.
RePhase appears to have ONLY a Windows download.
And as testiment to the complexity? No less that about a dozen 'tutorials'.
