Description
LIS8T / LIS8+T / LIS8XT Description
The Penton Audio LIS Series full-range, lay-in speaker packages are economical one-piece assemblies designed to speed installation in traditional 2′ x 4′ and 2′ x 2′ suspended tile ceilings. Conservatively rated each unit combines a speaker, 70.7/25-volt transformer and enclosure, all attached to grid assembly that also serves as a tile bridge.
The LIS Series exclusives wedged support lines up the grille with the tile. It is not just pleasing to the eye, but is convenient for the installer. Enclosure has 6″ five-conductor wire exiting the housings through the top.
Models use different assemblies; LIS8T and LIS8+T employing twin-cones and a 5-watt transformer. (The LIS8+T has a 15-watt speaker with a 10-ounce magnet.) An 8-watt transformer is stock on the coaxial LIS8XT which has a treated cone with rubber surround and a post-mounted, 3″ paper-cone tweeter having a 1/2″ moving coil.

Applications
LIS8T / LIS8+T / LIS8XT Applications
This family of products is for lightning-fast installation. When mounting in a traditional 2′ x 2′ or 2′ x 4′ dropped ceiling, only one perpendicular cut to the acoustical tile is needed.
The LIS Series is ideal for voice transmission, music and signal reproduction. Use these in commercial locations including offices, banks, educational institutions, restaurants, hotel/motels and other industrial/institutional/governmental applications where precise transmission of audio is required.
