EAW LS432i White 150W 2-Way Passive Column Speaker

Modern Column Array Loudspeaker for Fixed Installations
The EAW LS432i in white is a passive 2-way column loudspeaker designed for permanent installation in speech-focused environments requiring precise directional control. It features four 4-inch low-frequency drivers and three 1-inch soft dome tweeters arranged in a curved vertical array, creating a compact line source that delivers focused vertical dispersion with wide horizontal coverage. The LS432i is ideal for reverberant spaces such as churches, public buildings, transportation hubs, and corporate facilities where clarity and consistent sound distribution are critical.

Line Source Design Maintains Tight Vertical Control
Engineered to behave as a curved line source, the LS432i maintains a narrow 20° vertical coverage angle all the way down to 1000 Hz and retains an 80° vertical pattern even at 500 Hz. This focused vertical dispersion helps prevent excessive energy from exciting ceilings or floors, maintaining intelligibility in acoustically reflective environments. By limiting vertical spread, the LS432i improves speech clarity while reducing problematic reflections common in tall rooms or long corridors.

Wide Horizontal Dispersion Enhances Room Coverage
While the LS432i keeps vertical coverage narrow, it delivers a full 140° of horizontal dispersion thanks to its direct-radiating driver layout. This wide spread makes it a practical solution for spaces with broad seating areas or sidewall mounting locations. Listeners across the room receive balanced sound, reducing the need for multiple speakers and improving overall system efficiency without compromising fidelity.

Integrated Drivers with Frequency Shading for Consistency
To create a uniform output from top to bottom, the LS432i uses a combination of frequency shading and all-pass filtering. This technique ensures the four woofers and three tweeters blend as a coherent acoustic source without introducing lobing or inconsistent response. The result is consistent intelligibility and even frequency distribution throughout the listening area, whether used singly or in an array configuration.

Advanced Internal Crossover Provides Accurate Integration
The LS432i includes a complex internal crossover with asymmetrical filter slopes, going beyond basic signal splitting. This network aligns the frequency and phase response of the individual drivers, integrating them into a seamless whole. In addition to routing signal between woofers and tweeters, the crossover provides crucial equalization to maintain tonal balance and clarity at all volume levels.

Slim Profile and White Finish for Visual Integration
The enclosure’s slim, column-style form factor makes it visually unobtrusive in architecturally sensitive venues. Its white finish blends well into light-colored walls or pillars, making it an excellent choice for modern interiors, performance halls, or liturgical spaces where aesthetics matter. Though compact in appearance, the LS432i delivers the performance required for professional installation scenarios.

Ideal for Intelligibility in Reflective Spaces
When speech clarity is a priority, especially in reverberant or difficult acoustic spaces, the LS432i is a highly effective solution. It provides focused coverage that enhances spoken word intelligibility, particularly in distributed audio systems or as a standalone reinforcement source in small to medium installations. Its high-performance design and predictable pattern control help solve problems where traditional point-source speakers may struggle.
