EAW Passive 4" Column Speaker. 4 x 4" LF and 3 x 1" HF. Horz: 140˚ Vert: 20˚. White

The EAW LS432i White is a passive two-way column loudspeaker designed for permanent installation in professional sound reinforcement systems. It uses a line-source column design that integrates four 4-inch low-frequency woofers and three 1-inch soft dome tweeters to deliver clear and consistent full-range audio. The speaker employs advanced frequency shading and all-pass filtering to maximize line-source coupling while minimizing grading lobes and maintaining smooth sound coverage.

Its curved driver arrangement helps maintain a stable vertical coverage pattern, preventing collapse in the crossover region and ensuring uniform sound distribution across the listening area. At the same time, the drivers operate as direct radiators in the horizontal plane, producing wide horizontal coverage for improved intelligibility and fidelity. The internal passive crossover network uses complex asymmetrical slopes to properly integrate the low-frequency and high-frequency drivers while performing critical equalization functions.
