JBL Control 28-1 8" Two Way Vented Loudspeaker, Black

DESCRIPTION

The Control® 28-1 is a two-way 8” speaker with rich sonic character, wide coverage, consistent coverage, versatile mounting, and a contemporary highdesign look that fits into a wide range of decors, This makes Control 28-1 an excellent choice for a wide variety of applications, including retail stores, restaurants, health clubs, theme parks, educational facilities, hospitality, music cafes, leisure venues, and anywhere where a top quality high-output indoor/outdoor foreground/background music (and/or paging) speaker is required. The unique InvisiBall mounting hardware is included in with each system, making short work of permanent installation. The InvisiBall mounting method provides a high degree of both vertical and horizontal rotation, and because InvisiBall adjustments are made through a hidden access behind the logo badge, the grille never needs to be removed and there exists a high degree of theft deterrence as well. Integrated M6 mounting points for an optional U-bracket adds to the installation versatility.
