ELK-SP12F is a flush mount, interior speaker. It is ideal for alarm or voice applications and flush mounts for a clean, designer look. Installers will applaud the easy installation, utilizing standard, single gang electrical boxes. The low profile design and single gang wall plate size allows the unit to be unnoticed at outlet height. The impedance of 32 ohms allows multiple speakers to be connected in parallel, while maintaining an overall load rating that is acceptable for most security, access, and automation control panels.
