Thanks a lot for the peek behind the scenes!  (Now all you need is
a Wizard of Oz curtain, so you can tell people to pay no
attention...)

I was thinking that the new Alesis Q2 might be handy in this
application.  It has 8 signal processing blocks, each one can be a
reverb, delay, EQ or pitch shifter.  There are two inputs, two
outputs and internal patch bay.  You could put a signal into one of
the inputs and use an EQ block to cut the lows, and send that signal
out one output, take the same input signal and use a second EQ block
to cut the highs, run that to the other output.  Add a delay to each
block (programmable to 0.1 ms) to correct for timing errors in the
system.  You still have 4 blocks left for additional equalization,
reverb etc.  As the Q2's list is $800 and street price is under
$600, this seems like it might be a much more versatile alternative
to the traditional crossover/delay system.  Meanwhile when you're
not on tour, back in the studio you could use the same unit to add
reverbs, guitar effects etc.
Do you use special kind of cables?  I've always been a fan of banana
plugs for speakers, because they stay plugged in - and no other type
of equipment uses them, so it's less likely someone who wanders by
to "help out" will zap a poor mixer or direct box with 4,000 watts! 
But I read recently about a sound tech who wired speaker cables with
the circular 3-prong connectors used for 220V power outlets.  Of
course the speakers would fry if plugged directly into 220V mains,
but on the other hand, anyone who knows what that big plug is for
wouldn't be likely to be randomly plugging it in without showing
some respect!

The other day I was trying to look up the formulas for impedance
with serial or parallel connections but I couldn't find my notes.

Markertek's catalog lists a Furman AC power conditioner that is
supposed to automatically adjust for worldwide input voltages and
supply a clean 120V, about 2000W to a dozen outlets on the back, for
around $1700.  Maybe that would be a handy addition to your racks.
Have you tested your system's output with an SPL meter?
