Jeff Bagbys Universal Crossover Query

Rather than muddy my other speaker post I'll ask for answers here.
If I want to play "Mix&Match" with different boxes as Jeff talked about I'll want to put the XO in a separate enclosure and either use it as a base or as a divider and sit the second box on top.

Would the components get warm enough to need a ventilated box?
I've made standalone crossovers before but I've made those in old amplifier cases so I've never had to think about heat issues
 
There won't be much heat unless something is terribly wrong(like a short).
If you are running +20db peaks at 100w, your rms is a watt or so(including the energy in the sound produced,
and the warmth produced in the motor)
