My question is: Assuming the low-pass crossover is set to
40Hz, and the high-pass filter is set to 80Hz, what
happens to the frequencies between 40Hz and 80Hz
(Ignoring signals that are outside the roll-off curves)?


They get attenuated.


Are they simply lost?


Well, reduced.


In this system, the mains are
Maggie 3.6 planars, with response extending somewhat
below 40Hz, and I would prefer to feed bass above that
frequency to the Maggies rather than have them reproduced
by the subwoofer.


Why?

Why? Among other considerations, because I like the Maggie's response
above around 50Hz to 60Hz and wouldn't want to simply throw it away.

Incidentally, I have ordered one of the Paradigm X30 active crossovers,
and I'll report on the results of using it with the Velodyne to remove
the low bass otherwise sent to the maggies.

Also, I didn't get a response to my questions regarding the use of one
of the new HDMI 1.3 pre/pros or AVRs with Audyssey processors or
equivalent, which can also provide bass management. Would one of these
systems perform the same functions (crossover and bass management) as an
active crossover?
