JBL AC28/26-WH - 750W 2 x 8-inch Passive 2-Way Installation Loudspeaker with 120 x 60-Degree Coverage in White Finish

The JBL Professional AC28/26-WH is a compact, high-performance passive loudspeaker that combines powerful audio output with versatile mounting capabilities. Designed for professional installation, this 2-way full-range system offers exceptional clarity and coverage in both horizontal and vertical orientations. Finished in a sleek white DuraFlex finish, the AC28/26-WH is well-suited for environments where both performance and aesthetics are important. The loudspeaker features dual 8-inch low-frequency transducers, paired with a 1-inch exit compression driver and a 120° x 60° rotatable Progressive Transition (PT) waveguide, providing even and consistent coverage throughout the listening area.

With JBL's innovative technologies, the AC28/26-WH ensures that sound reproduction is natural and highly accurate. The dual woofers utilize Symmetrical Field Geometry (SFG) for improved bass response and reduced distortion, while the copper-clad aluminum edge-wound voice coils and copper-clad pole pieces further enhance performance by minimizing voice coil inductance. Filtered Array Technology (FAT) independently controls the magnitude and phase response of the dual woofers, ensuring smooth power response and constant coverage, regardless of the speaker's orientation. Whether used in the vertical or horizontal plane, the user-selectable crossover network guarantees precise high-frequency coverage pattern and performance.

Built to withstand the rigors of professional installation, the AC28/26-WH features a rugged 12 mm and 15 mm multi-ply hardwood plywood enclosure, designed for both durability and acoustic performance. The compact enclosure allows for easy installation even in tight spaces, making it ideal for under-balcony, column, or wall mounting. The heavy-duty, powder-coated steel grille with acoustically transparent foam backing ensures protection for the drivers while allowing for optimal sound quality. The speaker's versatile design includes multiple mounting points for an optional U-bracket, OmniMount type bracket, or a stand mount accessory, giving users the flexibility to install the speaker according to their specific needs.

With a frequency range of 53 Hz to 20 kHz and a frequency response of 65 Hz to 20 kHz, the AC28/26-WH delivers full-range sound with deep bass and clear highs. The speaker's 94 dB SPL sensitivity and 120 dB maximum SPL ensure high output and consistent performance even in larger spaces. The AC28/26-WH is capable of handling 375W continuous, 750W program, and 1500W peak, making it well-suited for demanding audio reinforcement applications. The loudspeaker is equipped with Neutrik Speakon NL4 connectors and covered barrier strip terminals, offering flexible and secure input options.

With an IP53 rating for environmental protection, the AC28/26-WH is designed to perform reliably in indoor and semi-outdoor environments where dust and water spray may be present. For higher environmental protection, optional weather-resistant versions (WRC and WRX) are available. The AC28/26-WH is a versatile, high-performing loudspeaker that delivers professional-quality audio with ease and reliability.
