The design guidelines spell out in no uncertain terms that
the
LFE channel must be summed with the full range channels first
and
then LPF. Therefore, any content in the LFE channel above
the
crossover frequency will be attenuated in the subwoofer
output.

I don't read "attenuated" as "lost". I guess that's a matter of
personal
interpretation.

"lost" was a poor choice of words on my part.

Of course something ridiculous like setting the preamp crossover
at 30Hz would knock the upper end of the LFE down
by -48dB...which is pretty close to being lost.
