Extron introduced the SF 8CT SUB, a ceiling-mounted subwoofer that completes the Extron ceiling speaker series by extending the low frequency response in music and high-performance audio applications.

The plenum grade SF 8CT SUB is integrated with other ceiling speakers in the system and is designed to be installed in a ceiling structure. The 8-inch (203 mm) low-frequency driver can provide bass even in smaller systems. SF 8CT SUB has low-impedance and high-impedance taps and integrated low-pass filter, which can flexibly meet various system requirements. SF 8CT SUB extends the low frequency range of any ceiling or program speaker system to increase impact.
