As to the pots, they could have been for
level, or phase adjustment. My money would be on level, in which case only
two legs being in use - i.e. with the pots connected as variable resistors,
one in series with the two tweeters in parallel, and one with the two mids
in parallel - would be the expected configuration.

In speaker crossovers, L-pads are generally used as L-pads -- just a
suggestion. Speaker manufacturers are extremely cost-conscious and
won't overspend -- especially on something that doesn't show.


If you put "passive three way crossover designs" into Google, you will get
an information overload on them, that you might be able to pick the bones
out of to decide on what your design originally was or needs to be.

Try back issues of Speaker Builder or the Audio Amateur for
information on crossover design. Also Siegfried Linkwitz's site.
