JBL Intellivox DSX430D Top-mounted Powered Column Speaker

The JBL DSX430D is a professional-grade powered column speaker engineered for high-intelligibility speech reinforcement and distributed audio in medium-to-large venues. Its integrated Class D amplification and Dante networking capability make it a flexible solution for installed sound systems, conference facilities, and venues requiring consistent, even coverage across wide listening areas.

Recording & Mix Presence

This system captures and reproduces 92 dB continuous and 95 dB peak SPL with a frequency response of 130–10 kHz, optimized for speech clarity and vocal presence in recording sessions. The 130° horizontal by adjustable vertical coverage pattern with a 50-meter typical throw ensures even sound distribution across large spaces without hot spots or dead zones—critical for accurate multi-mic placement and consistent phase relationships in studio recording scenarios.

Amplification & Signal Path

The onboard Class D amplifier provides 16 × 40W RMS continuous power (4 Ohm) with 470W peak capacity, delivering sufficient headroom for dynamic content and sustained output during tracking and playback. Dual connectivity options include transformer-balanced analog inputs via 3-way Phoenix connectors and full Dante digital audio networking with primary and secondary RJ-45 connectors, enabling seamless integration into modern networked audio systems and DAW workflows.
