Could a PC be used to minimize a resonance in a speaker box? For
example, if a woofer and a box had a combined peak at 140 Hz, could
you set up a PC to create a dip at 140 hz? I know this doesn't take
the room into account, but sometimes you can't do anything about
that.

As I said earlier in this thread, it depends what CAUSES that peak.

If it's a cabinet resonance, for instance, the size of the peak depends
on the level it's excited at. So you can't fix it with an equalizer,
because the equalizer can't compensate for something level-dependant.

If it's a horn resonance, for instance, the size of the peak depends
on the position of the listener in the room. So you can't fix THAT
with an equalizer either, because the equalizer can't compensate for
something position-dependant.

But there are some driver issues and cabinet-driver interactions
that you can fix with EQ.
