Our take on the JBL Control® 28-1

Need a little "oomph" in the music you play in your bar or restaurant? The JBL Control 28-1 speaker handles a robust 240 watts of continuous program power, so you can crank the volume when you need to. And it's ready to do the same out on the patio as well, thanks to a weather-resistant design that incorporates an 8" fiberglass woofer with butyl rubber surround and a 1" polyetherimide tweeter.

The JBL Control® 28-1 speaker looks good and sounds great in your place of business.

Play it loud, indoors or out

Need a little "oomph" in the music you play in your bar or restaurant? The JBL Control 28-1 speaker handles a robust 240 watts of continuous program power, so you can crank the volume when you need to. And it's ready to do the same out on the patio as well, thanks to a weather-resistant design that incorporates an 8" fiberglass woofer with butyl rubber surround and a 1" polyetherimide tweeter.

And you can mount it just about anywhere, as well. The InvisiBall® mounting system lets you make a permanent, but flexible installation, allowing 37 degrees of movement in the vertical plane and 40 degrees of horizontal rotation. The cabinet and grille can be painted to match any decor.

Flexible options for your place of business

The JBL Control 28-1 offers tap settings at 7.5, 15, 30, and 60 watts. That means you can daisy-chain multiple speakers throughout your establishment, with a single wire run and just one or two amplifiers. That range of settings lets you vary the relative volume based on where the speaker is placed. See what our satisfied customers have to say.

Crutchfield Customer Review (What's this?)

These speakers are great. We are using them in the 70V setup. They provide an awesome amount of sound and bass even in a large outdoor area in a pair. I would definitely recommend them to anyone using them in a commercial setup or outdoors. They are also super easy to hang and lock with the provided allen key, which is great as they are left unattended outside.

Control Contractor Series Surface Mount Speaker: The Control 28-1 is a two-way surface-mount loudspeaker with rich sonic character, wide coverage, consistent coverage, versatile mounting, and a contemporary design that fits into a wide range of decors. This makes Control 28-1 an excellent choice for a wide variety of applications, including retail stores, restaurants, health clubs, theme parks, educational facilities, hospitality, music cafes, leisure venues, and anywhere where a top quality high-output indoor/ outdoor foreground/background music (and/or paging) speaker is required.

Note: All JBL Control Contractor loudspeakers (both ceiling speakers and surface-mount models) are designed with a similar sonic signature, allowing for mixing and matching of the various models within an application, providing a similar tonal character throughout the entire listening area.

Two-Way Speaker Design: The Control 28-1 indoor/outdoor speaker employs a 1" PEI horn-loaded tweeter and a 8" woven fiberglass cone woofer for high fidelity sound performance. The horn-loaded 1" tweeter features a PEI diaphragm, low-viscosity ferro-magnetic fluid, and a lightweight Kapton voice coil former. The 8" woven-fiberglass cone features a pure butyl rubber surround with Weather-Edge frame protection, high-temp fiberglass voice coil former, high-temp voice coil wire, optimized cone geometry, linear suspension spider, and FEA optimized motor structure. Its speaker design ensures excellent sound character, providing pleasant, enveloping sound throughout the listening area.

  • 1" Tweeter: The horn-loaded 1" tweeter's low viscosity ferro-magnetic fluid increases voice coil cooling for higher long-term power handling. The PEI diaphragm delivers a smooth high frequency sound quality. A light weight Kapton voice coil former increases durability while providing better high frequency response extension. All these factors also contribute toward making the driver especially rugged for outdoor and other stressful applications. The Control 28-1's horn-loaded tweeter provides an even 100° x 100° coverage area to ensure excellent sound quality throughout the listening area.
  • 8" Woofer: The 8" woven fiberglass cone woofer provides durability and weather capable performance. The light weight high temperature fiberglass voice coil former and high temperature voice coil wire ensures stable performance under long-term high-power working conditions while also providing high sensitivity and high power capability. The pure butyl rubber surround delivers clean sound and ruggedness, while terminating its circumference in JBL's WeatherEdge (a seamless, rubberized extension of the woofer surround that provides added protection to critical transducer elements). Cone geometry is optimized for smooth frequency response and good off-axis performance, while an FEA optimized motor construction and linear suspension spider helps to lower harmonic distortion

Weather Resistance Enclosure: In addition to the driver designs contributing toward a high degree of weather resistance, the cabinet provides excellent endurance against sun, salt and moisture. Weather resistance is maximized by the Control 28-1 speaker's high-impact polystyrene (HIPS) cabinet and heavily zinc-plated grille. The Control 28-1 is available in a black or white finish; the cabinet and grille also accepts a variety of paints to match any décor. The Control 28-1 indoor/outdoor speaker is IP-44 rated and exceeds MilSpec 810 for humidity, salt-spray, temperature & UV. It also passes MilStd-202F for salt spray and ASTM G85 for acid-air plus salt spray.

70V/100V Compatible: Control 28-1 includes a 30W multi-tap transformer for use in either 70V or 100V distributed-line systems. Taps are selected with a rotary switch  located on the rear-panel.

  • 70V Taps: 60W, 30W, 15W, 7.5W
  • 100V Taps: 60W, 30W, 15W
Note: The Control 28-1 also features an 8-ohm pass-through setting.

Screw-Down Terminals: Speaker wire connection is made via weather-capable, screw-down terminals.

Mounting Options: The unique InvisiBall mounting hardware is included, making short work of permanent installation. The InvisiBall mounting method provides a high degree of both vertical and horizontal rotation. And, because InvisiBall adjustments are made through a hidden access behind the logo badge, the grille never needs to be removed and there exists a high degree of theft deterrence as well. Integrated M6 mounting points for an optional U-bracket adds to the installation versatility.

SonicGuard Protection: JBL's exclusive SonicGuard overload protection is virtually inaudible to the listener, ensuring reliability while providing full fidelity sound.

1 question already asked

My Control 28-1 speakers are packed away in their box for the winter, so my options for answering your question are limited. I checked the outside of the box as well as the printed material provided with the speakers, and no where is there any information as to where the speakers were manufactured. With that said, I would guess that they were assembled in China. I know that Harmon the parent manufactures many of their products in China. Sorry that I coudn't give you a definitive answer. You might try calling JBL's tech support. They are pretty good about answering consumer questions. [ RICHARD  Feb 13, 2018 ]
