One of the key features of the LA400 is its highly efficient low-frequency performance. This is achieved through its robust 15-inch neodymium driver, which is capable of delivering deep and powerful bass response. With a frequency range that extends down to 32 Hz, the LA400 ensures that it can handle the low-end demands of various musical genres and performance types.

Coupled with its impressive driver, the LA400 incorporates advanced technologies that enhance overall sound quality and maintain clarity even at high output levels. The integration of a high-performance crossover network allows for seamless integration between the low and high-frequency components, ensuring that sound remains coherent and balanced.

Another standout aspect of the LA400 is its flexible configuration options. The enclosure can be deployed as a standalone subwoofer or integrated into a larger audio system for increased bass extension. Its design allows for both horizontal and vertical placement, offering adaptability to different venue specifications and ensuring optimal sound distribution.

The cabinet of the LA400 is constructed from robust, lightweight materials that provide durability without sacrificing transport ease. The enclosure features a multi-ply birch wood construction, which not only enhances the acoustic qualities but also helps withstand the rigors of touring and frequent transportation.

Additionally, the LA400 includes multiple rigging points and transport handles, making it convenient for setup and breakdown. With its sleek and unobtrusive aesthetic, it fits seamlessly into various environments, from concert halls to outdoor festivals.

EAW’s commitment to innovation is reflected in the LA400’s compatibility with advanced DSP (Digital Signal Processing) technologies. This allows users to customize sound profiles and optimize performance based on the unique acoustics of any venue.

In summary, the EAW LA400 is a powerful and versatile subwoofer that excels in low-frequency performance while offering exceptional build quality and adaptability. Its cutting-edge technology, combined with thoughtful design elements, makes it an ideal choice for audio professionals looking for reliability and top-tier sound performance in any setting.
