Oh, folks, it gets better....

First, the case for capacitors on high-freq drivers.
High-freq drivers tend to not like lots of DC across
them. If your amp misbehaves, you are buying $300
worth of diaphrams for your Altec 806Bs. A $2 cap will
prevent this.

Now, accurate passive crossovers are difficult to make
for one simple reason: driver impedance is not
constant over frequency. And the cabinet can also
alter the impedance. Multi-amp setups eliminate this
problem.

Of course, a stack of TFM-25s or ST70s is gonna cost a
few paychecks...
