Note: Do not bend needles during this procedure.
5. Turn the speaker on its side and insert one steel needle (centering pin) into each
alignment hole in the backplate of the woofer (total of 8—these are the small
diameter holes, not the larger holes—see figure below), Ensure that the pins are
inserted completely.

6. Turn the speaker on its magnet with the cone facing up and align the pins so
that they are all touching the pole piece (toward the center not the outside
edge) and symmetrically arranged.
Note: If re-coning a 10" woofer see the alternate step 7 at the end of this section.
7. CAREFULLY lower the new Re-Cone Assembly (moving parts) into the basket
making sure that all of the pins are inside the voice coil, the illustration below
of the interior components of the woofer shows the correct positioning of the
steel needles inside the voice coil former. Align terminals, logo, and screw holes
before pushing the re-cone assembly in place. Minimize the amount of rotation
required to center the screw holes once in place. The assembly should slide
smoothly into place with just a small bit of friction between the pins and the
voice coil. Do not push down any further than is needed for the surround and
