3-way to active - Hypex FA253 - learning project

So, when I try ‘better measurements’, outdoors or large room, I plan to do:

- far field: individual drivers (twin for woofers) at 10degree or 15degree step 0 to 90degree (2m or so mic distance).

- near fields: individual drivers (twin for woofers) mic 2cm

Do I want to do anything else? E.g. boosted woofers? Full speaker with a test set of XOs?
 
WinISD sim shows max power 240W (and hitting xmax) at abt 30Hz with LT boost. Based on that and with power limiters applied (and thermal protection) I thought I should be OK. I did think to apply a steep high pass at abt 20Hz to limit excursion below 30Hz. And I also got advice here to do the same.
 
Archimago has tested the 2-ch amp that is used in FA253 - pretty good. Test runs start from 10Hz

The tweeter has mono amp NC100 which should be just as good. Lower gain though
 
Subjectively, it sounds perfectly transparent. I do not even think about the amps, only about crossover/EQ setup. And I don't think I will reach its power limits even when playing very loud. I am glad I went for the 253 - not 123 or 503. I think the 253 is just right for the project.
