It has a high durability, powder coated and perforated steel baffle, with a lightweight speaker assembly that includes an 8", fire retardant speaker with 10 oz. magnet and 4 Watt, 25/70V transformer with rotary tap selector and a line supervision capacitor. By providing high intelligibility, visual appeal and typical Quam reliability, the UL22DM is designed for a wide range of demanding applications.
