I128SYS specifications

The Atlas Sound I128SYS is a versatile and innovative speaker system designed to cater to a variety of audio applications. Engineered for high-performance sound reinforcement, the I128SYS is ideal for venues that require robust audio output with clarity and precision.

One of its standout features is the dual 8-inch woofers, which deliver impressive low-frequency response. These woofers are designed to handle high power, ensuring that the I128SYS can produce deep, rich bass that fills large spaces without distortion. Complementing the woofers are a 1-inch titanium compression driver and a high-frequency horn, which together provide smooth and articulate highs, enhancing the overall sound quality and ensuring a balanced audio experience across different sound frequencies.

The I128SYS incorporates advanced technologies such as passive crossover networks that optimize the signal distribution between the woofers and the drivers, allowing for efficient power usage and reducing the risk of speaker damage. This thoughtful design ensures that the speakers can handle high levels of input power while maintaining audio fidelity.

Durability is another key characteristic of the Atlas Sound I128SYS. Constructed with a rugged plywood cabinet, the system is built to withstand the rigors of professional use, making it suitable for touring, installations, and live events. The enclosures are treated with a durable finish that helps resist scratches and dents, preserving the system’s aesthetic appeal over time.

The system is also user-friendly, equipped with multiple connection options, including professional-grade speakON connectors and binding posts, providing flexibility for various audio setups. This makes it easy to integrate the I128SYS with existing gear or to use it in a standalone configuration.

Lastly, the I128SYS is designed with sound dispersion in mind, featuring an innovative waveguide that broadens the coverage area. This ensures that sound is evenly distributed throughout the venue, allowing audiences to enjoy a consistent listening experience regardless of their location.

In summary, the Atlas Sound I128SYS is a powerful and reliable speaker system that combines advanced technology, rugged construction, and user-friendly features, making it an excellent choice for professionals seeking high-quality audio reproduction.
