Description

The Penton Audio LIS Series full-range, lay-in speaker packages are economical
one-piece assemblies designed to speed installation in traditional 2Â’ x 4Â’ 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 exclusive swedged 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 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.
