In Volume 3 >> Bipolar Junction Transistors, you show transistor amplifiers loaded with a speaker; It looks like you're pretending the speaker is a resistance rather than an inductance, have I got that right?

Thanks.

This should have been in the Electronics Chat forum. Ever measure the resistance of a speaker? I have, if it says 8Ω it will likely have 8Ω give or take a bit. This inductance at audio isn't that significant, though it is there.
