JBL VTX S28 - 4000W 2 x 18-inch Passive Arrayable Line Array Subwoofer with 8-Ohm Impedance in Black Finish

The JBL Professional VTX S28 is a powerful, high-output subwoofer designed to deliver maximum sub-low frequency performance with exceptional impact and precision. Engineered for demanding sound reinforcement applications, the VTX S28 features two JBL 2269H 18-inch transducers that utilize Differential Drive technology. These transducers, equipped with dual neodymium magnets and dual voice coils, are optimized for ultra-long excursion, enabling the VTX S28 to produce deep, resonant bass with outstanding clarity, even at extreme output levels. With a rugged, road-ready design, the VTX S28 is perfect for both touring and permanent installations that require consistent and reliable performance.

The VTX S28 offers versatility in deployment, supporting both front-firing and cardioid configurations. In cardioid mode, which is achieved by configuring multiples of three VTX S28 enclosures (two front-firing and one rear-firing), it provides significant broadband SPL rejection of up to 15-25 dB behind the array, making it ideal for environments where minimizing low-frequency spill is critical, such as live performances or broadcast events. The cardioid configuration reduces stage reflections and prevents low-end interference, ensuring a cleaner sound profile for the audience. The system's flexibility is further enhanced by its ability to be suspended or ground-stacked in any configuration, with integrated suspension hardware for quick and easy setup.

Equipped with BSS Audio OmniDrive HD V5 processing and fully integrated with JBL HiQnet Performance Manager control, the VTX S28 allows for precise system configuration and deployment. The HiQnet Performance Manager provides users with intuitive control over the system, ensuring optimal integration with the rest of the VTX Series systems. The VTX S28 can be deployed in various configurations, including as a companion subwoofer for the VTX V20 or VTX V25-II systems, with full compatibility for extending the low-frequency line length or enhancing underbalcony coverage in large-scale arrays.

The system is powered by two 2269H 18-inch Differential Drive subwoofers, which deliver a frequency range of 24 Hz to 400 Hz and a maximum peak output of 144 dB SPL (half-space). The system's impressive low-frequency output is coupled with JBL's advanced direct cooling design, ensuring that heat dissipation is maximized during high-output performance. This setup allows the VTX S28 to maintain superb fidelity and linearity, even at the highest power levels. With a continuous power rating of 2000 W per transducer and a peak power handling of 8000 W, the VTX S28 provides an uncompromising performance capable of handling even the most demanding bass requirements.

The VTX S28 features a sturdy 18 mm, 11-ply Finnish birch plywood enclosure with a black DuraFlex finish, offering durability and a sleek, professional appearance. The enclosure includes integral recessed handles and a powder-coated 14-gauge hex-perforated steel grille with acoustically transparent black cloth backing, ensuring protection for the internal components while allowing for optimal sound transmission. With a net weight of 183 lbs and dimensions of 19.5 x 48.1 x 36.3 inches, the VTX S28 is designed to be both robust and manageable, ensuring ease of transport and setup while delivering exceptional performance on stage or in the field.
