Broad Band Voice CapableHarsh Environment Voice Capable

The KSN 1090A and 1103A are extended fre-quency range piezoelectric speakers designed to provide voice reproduction as well as higher frequencies. These speakers are lightweight with thin proles, but robust enough to handle 50 W (EIA). The KSN 1090A and 1103A are de-signed for applications that require a broad fre-quency range, small size, lightweight, non-magnetic, rugged speaker.

The KSN 1103A utilizes a high strength pheno-lic cone which provides the resistance to hu-midity required for use in harsh environments.
