The JBL Professional Control 128WT is a premium in-wall loudspeaker from the Control Contractor line, designed to provide exceptional performance for applications where minimal visual impact is essential. Perfect for venues such as boardrooms, conference rooms, airports, retail outlets, museums, restaurants, cruise ships, and other critical listening spaces, this speaker offers a blend of high-performance audio and a sleek, unobtrusive design. The Control 128WT is particularly well-suited for situations where the speaker needs to deliver clear, full-range sound while blending seamlessly into its environment.
At the heart of the Control 128WT is an 8-inch polymer-coated aluminum-cone woofer, designed for deep, accurate low frequencies down to 30 Hz. The pure butyl rubber surround ensures a long lifespan and high reliability even under heavy use, while the extended-polepiece magnet design allows for greater excursion and tighter bass response. The speaker's high-frequency driver is a 1-inch pure titanium dome, which is mounted on a low-diffraction swivel mount with -10° aimability. This configuration provides precise control over the high frequencies, ensuring smooth, distortion-free sound and consistent coverage across the listening space. The built-in EOS (Elliptical Oblate Spheroidal) waveguide further enhances the high-frequency response by reducing distortion and ensuring a more accurate, natural sound reproduction.
With a frequency range of 30 Hz to 20 kHz and a sensitivity of 90 dB at 1W/1m, the Control 128WT is capable of delivering powerful sound while maintaining clarity, making it ideal for both music and speech applications. The speaker features a high-slope crossover network to ensure a seamless transition between the low and high frequencies, preserving the integrity of the midrange and providing even coverage throughout the space. The speaker's wide coverage pattern of 180° horizontal and 160° vertical (average, 1 kHz - 8 kHz) makes it an excellent choice for spaces that require broad sound dispersion without the need for multiple speakers.
One of the standout features of the Control 128WT is its versatility in installation. The speaker includes multiple transformer taps for 70V and 100V systems, with settings for 50W, 25W, and 12W taps, as well as an 8-ohm direct input. This makes it easy to integrate into distributed audio systems in a variety of configurations, whether for low-impedance or high-voltage applications. The multi-tap transformer ensures that the speaker can be used in both commercial and residential installations, offering flexibility in power handling and impedance options.
In terms of installation, the Control 128WT fits into standard stud-wall construction with a cutout size of 11.9 x 8.9 inches, and a shallow depth of only 4 inches from the wall to the back of the speaker. This slim profile makes it ideal for applications where space is at a premium, such as in-wall installations in offices, retail spaces, or multi-purpose rooms. The included cutout template and paint shield ensure a professional installation, and the baffle and grille are paintable to match any decor. For new construction, the optional WB8 Rough-In Frame allows for easy installation into wall studs.
Built for durability, the Control 128WT features an IP54 rating for dust and water resistance, making it suitable for both indoor and outdoor installations. The drivers are water-treated, and the grille has a water-backing to protect against environmental factors. This rugged construction ensures reliable performance in a variety of settings, even in areas with high humidity or exposure to the elements.
