Description
The Control 19CST is a high-performance in-ceiling subwoofer designed for distributed audio systems where deep, powerful bass is required from a discreet installation. It uses JBL’s advanced acoustic engineering, including the Nested Chamber™ design, to deliver strong low-frequency output from a compact ceiling-mounted enclosure.
This model features an 8-inch (200 mm) long-excursion driver that provides tight, controlled bass response suitable for commercial environments such as retail spaces, restaurants, hotels, and public venues. It is designed for use with 70V/100V distributed audio systems, making it highly flexible for large-scale installations.
The system comes pre-packaged with grille, backcan, and tile rails, ensuring fast installation, while its plenum-rated construction and safety certifications make it suitable for air-handling ceiling spaces.
