The JBL SCL-2XL 2.5-way Quadruple 8-inch In-Wall Loudspeaker brings reference-level JBL Synthesis performance to a completely integrated architectural design. Engineered for high-output left, center, and right channel applications behind acoustically transparent projection screens as well as demanding surround-channel installations, the SCL-2XL combines four 8-inch woofers with JBL's advanced compression-driver and horn technology to deliver the dynamics, clarity, and controlled dispersion required for large and extra-large home theaters.
At the heart of the SCL-2XL is JBL's patented D2815 dual-diaphragm, dual-motor compression driver coupled to a large-format High-Definition Imaging horn. Four cast-frame Advanced Aluminum Matrix cone woofers operate within a sophisticated 2.5-way network, allowing the loudspeaker to be installed vertically or horizontally while maintaining consistent acoustic performance. An integrated sealed MDF backbox, Sonoglass baffle, isolation mounting system, bi-wire/bi-amp capability, and zero-bezel paintable grille make the SCL-2XL equally focused on reference performance and professional architectural integration.
Key Features & Innovations
Reference-grade architectural loudspeaker — the JBL SCL-2XL 2.5-way Quadruple 8-inch In-Wall Loudspeaker is engineered for high-output LCR and surround applications in large and extra-large dedicated home theaters.
Quadruple 8-inch Advanced Aluminum Matrix woofers — four 200mm cast-frame woofers provide substantial cone area and dynamic capability for powerful midbass, effortless output, and the scale required for cinematic reproduction.
Patented D2815 compression driver — JBL's 1.5-inch dual annular ring Teonex diaphragm design uses a dual-diaphragm, dual-motor architecture engineered for high output, low distortion, and exceptional clarity.
Large-format High-Definition Imaging horn — the compression driver is coupled to JBL's patented HDI horn geometry to provide broad, controlled dispersion and consistent sound throughout the listening area.
Advanced 2.5-way architecture — the four woofers operate within a carefully engineered 2.5-way network that allows the SCL-2XL to maintain excellent dispersion characteristics whether installed vertically or horizontally.
500-watt RMS power handling — substantial power handling and 92dB sensitivity give the SCL-2XL the dynamic capability needed for demanding reference-level home cinema systems.
Integrated sealed MDF backbox — unlike open-back architectural speakers, the SCL-2XL incorporates its own optimized enclosure to provide predictable acoustic performance and greater isolation from the surrounding wall structure.
Sonoglass baffle and isolation mounting system — the rigid molded baffle integrates the HDI horn while JBL's isolation mounting design helps mechanically separate the loudspeaker enclosure from the wall structure.
Bi-wire and bi-amp capability — dual gold-plated input terminals and the premium crossover network provide additional system-design flexibility for advanced installations.
Zero-bezel paintable grille — the magnetically attached white grille can be painted to coordinate with the surrounding wall, allowing the substantial loudspeaker system to visually disappear into the room.
FAQ — JBL SCL-2XL
Can the JBL SCL-2XL be used as an LCR speaker?
Yes. The SCL-2XL is specifically designed for high-output left, center, and right channel applications. It is particularly well suited to installation behind an acoustically transparent projection screen, allowing three matching SCL-2XL loudspeakers to create a consistent front soundstage.
Can the SCL-2XL be installed horizontally?
Yes. Its 2.5-way network configuration is engineered to allow either vertical or horizontal installation without the significant lobing and dispersion problems commonly associated with conventional multi-driver horizontal speaker designs.
How much power can the SCL-2XL handle?
JBL rates the SCL-2XL for 500 watts RMS of power handling using the CEA-426B specification at its rated load impedance. Its 92dB sensitivity also helps it achieve substantial output for demanding home theater applications.
Does the SCL-2XL include a backbox?
Yes. The SCL-2XL incorporates a sealed MDF backbox as part of the loudspeaker system. This provides a controlled enclosure volume and helps isolate the speaker acoustically from the surrounding wall cavity.
Can the SCL-2XL be bi-amped?
Yes. The loudspeaker has dual sets of gold-plated spring-loaded binding posts and supports both bi-wiring and bi-amplification. The internal crossover remains part of the signal path when using these configurations.
How does the SCL-2XL compare with the SCL-2?
The SCL-2XL expands on the SCL-2 concept with four 8-inch woofers rather than three, a newer D2815 compression driver, 500-watt RMS power handling, and a larger enclosure. Both are high-performance 2.5-way in-wall designs, but the SCL-2XL is engineered for even greater output capability in demanding large and extra-large theater systems.
