PendantConnect™ speaker cable is an Extron exclusive hybrid design incorporating the speaker wires and steel support cable into a single outer jacket, allowing the integrator to achieve an absolute vertical hang with only a single visible cable. PCC-1 cable is used exclusively for the SF 3PT SoundField Pendant Speaker while PCC-2 cable is used exclusively for the SF 26PT SoundField Pendant Speaker.

This audio tool calculates cut, strip, and reference mark points for PendantConnect speaker cable based on ceiling height and desired speaker height.

The calculator on this page is used when pre-cutting cable prior to cable termination. The simplified formula below may be used when the PendantConnect speaker cable has already been terminated at the speaker end.

• Room Height - Bottom of Speaker Height = Cut point on cable, measured from the top of the speaker cap. Then strip six inches down from the cut point.
