An inductor in parallel with a tweeter, without a series capacitor,
would be seen by the amp as a short at low frequencies. A cap in
series with a woofer would roll off the low frequencies.

Agreed, and that leaves some non-simple problems to solve.

No it doesn't.

AFAIK the very few commercial designs with an inductor in parallel with the
tweeter use a tweeter that is more efficient than the woofer, and put a
resistor in series with the inductor/tweeter combination. Still not a pretty
picture.

Sorry, but you're both pretty clueless as to what was described.
This is hardly an uncommon crossover design, and was fairly
well described 3 decades and more ago, for example, Small, R. H.,
"Constant Voltage Crossover Design," Proc IREE Australia vol 31
(1970), reprinted in J. Audio Eng. Soc. 1971 Jan:

"the series network in Fig 10b [EXACTLY the topology I
described] in inherently advantageous because tolerances
in the component values, both in the crossover and in the
termination, will have no effect on the total network
voltage response. Because the drivers are connected in
series across the amplifier output, the sum of the voice-
coil voltages must always be equal to the driving voltage."

As both explained AND demonstrated in my other response to these
assertions, it is hardly a "non-simple problem," indeed, it is
no problem at all, having some significant advantages.

How about actually LOOKING at the circuit and UNDERSTANDING it?
