The JBL CONTROL 128W is an 8-inch in-wall loudspeaker from the Control Contractor series, specifically engineered for high-performance distributed audio systems in commercial and upscale residential installations. This model is designed for flush mounting within standard wall construction, providing a discreet, space-saving audio solution that delivers robust, full-range sound. Its primary application is in environments where aesthetic integration is paramount, such as boardrooms, restaurants, hotels, retail spaces, and custom home theaters, offering high-fidelity background music and voice reinforcement without occupying floor or shelf space. The speaker's design ensures it can be seamlessly incorporated into interior design, with only a paintable grille visible on the wall surface.

The speaker features an 8-inch mineral-filled polypropylene woofer and a 1-inch soft-dome tweeter, configured in a two-way design for balanced frequency response and clear audio reproduction. It is equipped with a built-in multi-tap transformer, making it fully compatible with 70.7V and 100V constant-voltage amplifier systems, which are standard in commercial installations for their ability to drive multiple speakers over long cable runs efficiently. This transformer allows installers to select the appropriate power tap to match the acoustic requirements of the specific zone, optimizing system headroom and performance. The speaker also supports a direct 8-ohm mode for low-impedance applications, adding to its installation versatility.

Installation is facilitated by a rigid, rust-resistant steel frame with integrated dog-ear mounting brackets that secure firmly to wall studs or cross-bracing. The design includes a depth-adjustable baffle to accommodate varying wall thicknesses and ensure a flush, professional finish. The grille is magnetically attached and paintable to match any wall color or finish. With its combination of substantial output capability, flexible voltage operation, and a purpose-built in-wall design, the JBL CONTROL 128W provides a reliable and high-quality audio solution for integrators seeking to deliver powerful, clear sound from an invisible source.
