JBL Intellivox DSX430 – 2-Way Long-Throw Digitally Steerable Column Array (Amp Bottom)

Product Overview

The JBL Intellivox DSX430 (Amplifier at Bottom) is a 2-way self-powered digitally steerable column loudspeaker from the DSX series, providing 50-meter long-throw coverage with DDS vertical beam steering for demanding commercial AV fixed installations. Combining 13 custom 4-inch full-range drivers with 8 horn-loaded 1-inch dome tweeters, the DSX430 delivers extended high-frequency horizontal dispersion and speech clarity suited to theatres, large conference halls, houses of worship, and atriums. The bottom-mounted 16-channel Class-D amplifier is the preferred configuration when wiring enters from the lower wall or floor level, facilitating clean cable routing in commercial installations. WinControl software provides full DSP beam steering control without requiring physical adjustment of the installed column.

Product Description

The DSX430 Amp Bottom uses the same 2-way 13 + 8 driver complement as the Amp Top variant, with all audio and coverage specifications identical — the only physical difference is the location of the integrated amplifier module at the bottom of the array. This configuration is selected by AV system designers when floor-level or lower-wall conduit entry points are dictated by the building infrastructure or architectural requirements of the installation. DDS technology delivers software-configurable vertical beam shaping through WinControl, allowing tilt angle and beam width to be adjusted remotely after installation. The 16-channel Class-D amplifier, paired with a switched-mode power supply, supports long-term reliable operation in fixed commercial deployments. Dual line inputs accommodate primary and backup signal routing, and onboard DSP handles equalization, delay, and beam management. The slim 5.28-inch column profile and black or white color options support discreet integration into varied commercial interior environments across large conference facilities, transport terminals, performing arts venues, and places of worship.

Key Features

• 2-Way Driver Configuration — 13 × 4-inch full-range drivers plus 8 × 1-inch dome tweeters extend high-frequency dispersion and improve speech clarity and program audio fidelity.
• Amplifier at Bottom — Bottom-mounted 16-channel Class-D amplifier suits installations where wiring enters from the floor level or lower wall, simplifying cable management in commercial spaces.
• 50-Meter Coverage Distance — Long-throw capability replaces distributed ceiling speaker systems in large lecture halls, theatres, atriums, and assembly spaces.
• DDS Digital Beam Steering — Digital Directivity Synthesis technology provides WinControl software-configurable vertical beam shaping, suppressing reflections in reverberant architectural environments.
• Integrated 16-Channel Class-D Amplification — Self-powered design eliminates external rack amplifiers, reducing system complexity and equipment room requirements.
• Up to 18 kHz Frequency Response — Extended frequency range supports both speech reinforcement and full-range program audio applications in commercial venues.
• Dual Line Inputs — Supports primary and redundant signal feeds for resilient commercial AV system configurations.
• Slim Architectural Column Profile — 5.28-inch width and black/white finish options enable discreet integration into architecturally sensitive commercial spaces.

Typical Applications

• House of worship — large sanctuaries requiring 50-meter 2-way coverage with DDS beam steering and bottom wiring access from floor-level conduit
• Auditorium — performing arts and lecture venues where bottom-entry wiring is preferred and 2-way HF clarity is required
• Conference room — large conference halls requiring long-throw speech intelligibility with enhanced high-frequency performance
• Transportation terminal — airports and transit facilities requiring long-throw wall-mount column paging with floor-level cable routing
• Training room — large educational and corporate training spaces requiring consistent long-throw coverage with high intelligibility
• Multi-purpose room — flexible-use commercial spaces needing remotely reconfigurable coverage without physical changes to the installed column

Frequently Asked Questions

What is the difference between DSX430 Amp Bottom and Amp Top?

Both models are electrically and acoustically identical. The Amp Bottom places the amplifier module at the lower end of the column — the practical choice when conduit and wiring enters from the floor or lower wall. The Amp Top version routes cabling from the ceiling or upper wall. Coverage performance, driver complement, and DSP capabilities are the same for both configurations.

How does the DSX430 differ from the DS430?

The DSX430 adds 8 dedicated 1-inch dome tweeters to the driver array, providing enhanced high-frequency horizontal dispersion for improved audio fidelity in 2-way operation. The DS430 is a single-way design without dedicated HF drivers. Choose the DSX430 when high-frequency clarity for music or mixed-use audio is a project requirement.

Does the DSX430 require an external amplifier?

No. The DSX430 is fully self-powered with an integrated 16-channel Class-D amplifier. It connects directly to line-level sources and requires no external rack amplification.

What software manages beam steering on the DSX430?

JBL's WinControl PC software is used to configure and manage beam steering, equalization, and system parameters. Contact Creation Networks for software setup guidance or project support.

What warranty applies to the JBL Intellivox DSX430?

JBL Professional products carry a limited manufacturer warranty. Commercial installation warranty terms should be verified with an authorized distributor. Creation Networks supports warranty coordination for commercial AV installations.
