I got an XTZ 99W12DSP subwoofer which has 5 parametric EQ filters and 10 graphic EQ filters.
For REW, I pick the "Generic Equaliser" and setup 5 Auto PK filters and 10 Manual PK filters with
the 10 static frequencies and the Q-value of 5.1.
I then run the "match response to target" and then change the Manual filters to Auto
and then run the "optimise gains" function and then change the Graphic EQ filters
back to Manual and then run "match response to target" again.
My thinking is that REW then can take some slight advantage of the static graphic EQ filters.
Is this the correct / best way to do it with the available filters I have at my disposal?

I think that the optimial thing would be if there was a filter to select which has Control Auto with the type of Graphic EQ (instead of PK)
which would have a fixed frequency and Q-value (entered by the user but not touched by REW) but
let REW adjust the gain value at the same time when it adjusts all the PK filters but as far as I could see,
there is no such filter to select.

Sounds a plausible approach. There isn't a graphic EQ equivalent, probably as quick adjusting those live using the Pink PN excitation and watching the response on the RTA - don't need any averaging, so update is fast. Can use these settings:

There isn't a graphic EQ equivalent,

Well, setting control to "Auto", type "PK" and manually enter frequency and Q and let REW decide the gain by "optimise gains" basically give you Graphic EQ support.

probably as quick adjusting those live using the Pink PN excitation and watching the response on the RTA - don't need any averaging, so update is fast.

The point with entering the Graphic EQ filters in REW is that REW is aware of them and can build the PEQ filters with those "in mind".
That is lost when using the RTA approach.

One approach I will try is to:
1. disable the 5 PEQ filters
2. set the 10 GEQ filters to control to "Auto", type "PK" and manually enter frequency and Q and let REW decide the gain by "optimise gains".
My thinking is that REW then uses the "Graphic EQ" filters as best as it can.
3. set the 10 GEQ filters to control to "Manual".
4. enable the 5 PEQ filters, control to "Auto"
5. run "match response to target"
and here I hope uses the 5 PEQ filters to further improve on what was done in step 2.
