Designed for AVMaxx shoppers who demand high output, scalability, and professional performance, this system is built for live concerts, mobile production, clubs, houses of worship, corporate events, touring applications, and rental companies that need dependable, concert-level sound.
The DVA T4 is a compact 3-way active line array module engineered to deliver impressive output from a lightweight and highly scalable enclosure. Its driver configuration includes an 8-inch neodymium low-frequency driver, 6.5-inch neodymium midrange driver, and dual 1-inch neodymium high-frequency compression drivers. Each enclosure features a 420W RMS Digipro Class-D amplifier, 24-bit/48kHz DSP processing, multiband RMS/peak/thermal limiting, and integrated professional rigging hardware. With 100° x 15° dispersion and output reaching up to 128 dB maximum SPL, multiple T4 modules can be combined to create powerful arrays for a wide range of professional applications.
Providing the low-frequency foundation is the DVA S20DP, a high-output active bass-reflex subwoofer equipped with dual 18-inch drivers featuring 4-inch voice coils. A powerful 2,000W RMS Digipro amplifier provides the muscle required for demanding live sound applications, delivering up to 138 dB maximum SPL. Selectable 90Hz/120Hz crossover settings, phase control, and integrated RMS, peak, and thermal protection provide additional flexibility when configuring the system.
The self-powered architecture eliminates the need for separate external power amplifiers while providing amplification, DSP, and protection engineered specifically for each enclosure. The modular DVA design allows additional line array modules and subwoofers to be deployed as system requirements increase, making it an excellent platform for both portable production and permanent professional installations.
Whether you're building a system for concert production, live entertainment, DJ events, clubs, churches, corporate events, or professional rentals, the combination of compact line array technology and powerful dual 18-inch subwoofers delivers the output, coverage, and flexibility demanded by professional applications.
