X3 dudes
Step a) Get 2 kef kc62 subs. Face reality, the X3 small drivers are meant to do something else very good, not get you down to 20 hz and qualify as a full range speaker. It is also meant to be a sleek looking speaker, not some fat eye sore.
Step b) Get a amp with "true bass management", such as a Yamaha R-N2000A. (Not sure what else is out there..maybe rotel michi, etc). Send everything 100 hz and under to the subs and 100 hz & above to the borresen bass drivers...watch the X3 drivers spring to life and do what they do best.
Step c) Get something like a Wiim ultra streamer with peq and adjust to taste (actually, this unit has bass management too). RME dacs have peq, etc...or you could go full prepro non-purist like deep_333 (a very very non-puritan guy).
Reason is.....Everyone’s psychoacoustically adjusted hearing is different. You won’t hear what Erin did and rest assured that hamster hears all kinds of things (that he claims is subjective listening) after he sees the measurements.
Step d) Watch your X3 slay and filet the Harbethany priced twice as much, the Fleetwoods priced twice as much, other BBC junkboxes and all kinds of other junk in the 10k, 20k, price bracket.
Good luck
