Kudos to Joseph Audio for going the other way, and actually adding crossover components
That’s just adding series resistance to the perceived load to make it look higher to the amps output stage so it doesn’t complain, and what that does is lower the damping factor and raise the output impedance as seen by the amp
You get a similar effect by using a ZERO output transformer with amps that aren’t right, and we all know know that is just a band aid fix, better off having the right amp to start with.
