AudioBahn AS31V Operating Instructions Manual page 6

When using one of the AS series 2-way speakers, the tweeter is fully removable. When
removing the tweeter, make sure to replace the chrome plug in its place. This is needed for
proper operation of the speaker. To remove the plug or tweeter grip your fingers on the
outside of the tweeter or plug and gently pull up with a tilting action slightly from side to
side and it will pop out. To replace the plug or tweeter, line up the holes at the bottom of
the plug or tweeter with the markings on the cup on the speaker.
When using the tweeter installed in the speaker or mounted separately, the blue wire with
the black line is - (negative) and the solid blue wire is + (positive).
