JBL Pair 8 2-Way In-Wall Speaker,

The Control 128W is a premium in-wall speaker within the JBL Professional Control Contractor line designed for applications such as foreground music, boardrooms, reception areas, airports, convention centers, cruise ships, retail outlets, restaurants, museums, surround locations, or any critical listening application where top performance from a loudspeaker with minimal visual impact is required.
The high-performance woofer features a polymer-coated aluminum cone for high performance down to 30 Hz and pure butyl rubber surround for long-life and high reliability along with extended-polepiece magnet design for long excursion and tight, low bass. The pure titanium dome high frequency driver is loaded with a built-in EOS (Elliptical Oblate Spheroidal) waveguide for low distortion and a smooth frequency response. A low-diffraction swivelmounting system enables the user to direct high frequencies where required without the diffraction distortion inherent in other aimable tweeter designs. A high-slope crossover network maintains natural midrange sound and produces more even coverage throughout the listening area. The optional Control 128WT version includes a multitap transformer for 70V/100V systems.
