As a non-techie person, this issue has caused me some consternation. Obviously, the power output of any amplifier has to go down, eventually, as impedance of the load rises. Otherwise, crossovers would not work as advertised. But it also occurred to me that tube amplifiers, and OTL tube amplifiers in particular, may drive crossovers more efficiently than do, say, solid state amplifiers with either very low output impedance, very limited voltage capability, or both. Thus, it could be said that the speaker crossover ought to be designed with the type of amplification in mind. An OTL might sound different from an SS amplifier on a given multi-way speaker, for that reason alone.Ralph, can you comment? Thanks.

The issue is that the output impedance of some amps is high if they don't run feedback, and low if they do.
This can affect how the crossover works.
