    That is a symbol for a connector, in this case a faston connector.

    I have never had to draw a "dangling 6" piece of wire with a female spade connector (faston) before.

    Certainly doesn't explain the weird-**** problem of ONLY sub-bass pair sounding like a crackling buzz only on deep piano type notes. Played the crap out of a ton of material, loud, and no such sound ever, with my ear right on those 2 drivers. Dropped extra regular 6511ish driver in place of top driver, still heard it, jist a little clearer than donut driver. Swapped preamp L and R and the problem stayed in the right speaker where it started.

    I cut my schematic pic off not showing that that wire entering the XO board via "P" goes straight to ground.

    :/

    There are quite a few people living in this area with the surname of Glotfelty, a common Mennonite name.

    I did an internet search for "Glotfelty and Polk Audio" and there he is: David Glotfelty, former project manager for Polk Audio, Hopkins graduate and Baltimore native son. Another piece of Polk history.
