HARMAN Luxury Audio Group has dropped a glut of new speakers while exhibiting at ISE 2026, introducing nine new loudspeakers to the JBL Synthesis Custom (SCL) line alongside three processing and amplification components, making it the brand’s largest product overhaul in a long while.
Designed as a System, Not Standalone Products
Rather than envisioning them as isolated products, JBL Synthesis says it designed the 2026 lineup with a system-level approach in mind for its immersive audio line.
“Loudspeakers, processing, amplification and subwoofers are developed together to ensure consistent voicing, predictable performance, and scalable system design across a wide range of residential applications,” notes JBL in a press release detailing the launch.
Adding onto this statement, Jim Garrett, Senior Director, Product Strategy and Planning, HARMAN Luxury Audio is quoted separately as saying, “With this new generation of JBL Synthesis loudspeakers and electronics, we’re delivering the most complete and flexible immersive audio ecosystem we’ve ever offered.”
More About the New JBL Synthesis SCL Lineup
The new JBL Synthesis Custom Loudspeakers span both architectural in-wall designs and new in-room and on-wall solutions with all models being timbre-matched and engineered to integrate simply within complete JBL Synthesis systems.
SCL In-Wall Loudspeakers

Designed for architectural installations, the new SCL in-wall models update and expand the flagship lineup with the latest JBL transducer technologies, compression drivers and HDI horn geometry. The series includes four models:
- SCL-2XL—A high-output, reference-grade speaker with quad 8-inch woofers for LCR applications behind acoustically transparent screens in large and extra-large rooms.
- SCL-4XL—A dual 8-inch speaker designed for wide, consistent coverage and balanced performance as a cinema speaker.
- SCL-6XL—A quad 6.5-inch speaker tuned to deliver high performance with installer-friendly features and efficient architectural integration.
- SCL-7XL—A dual 6.5-inch in-wall loudspeaker with an offset HDI horn design that allows sound to be precisely aimed toward the listening area, ideal for surround and center-channel applications.
SCL In-Room and On-Wall Loudspeakers

JBL Synthesis Processing and Amplification
Complementing the expanded loudspeaker lineup, JBL Synthesis is also introducing three advanced electronics designed to anchor modern immersive systems:
- SDP-70 Immersive AV Processor—A 24-channel processing platform offering advanced Dirac Live Active Room Treatment (ART) and network-ready architecture.
- SDP-60 Immersive AV Processor—A 16-channel processor equipped with reference-grade decoding, balanced outputs, Matrix Channel Assignment and support for Dirac Live ART optimization.
- SDR-40 Immersive AV Receiver—An all-in-one solution combining 16-channel processing with nine channels of Class G amplification, delivering high output, efficiency and streamlined system deployment.
The components also support supporting Dolby Atmos, DTS:X Pro, IMAX Enhanced and AURO-3D immersive formats.
