CM500i specifications

The Phase Technology CM500i is a sophisticated solution designed for audio enthusiasts seeking high-quality sound reproduction in a compact form factor. Renowned for its innovative features and advanced technologies, this loudspeaker is engineered to deliver an exceptional audio experience, making it suitable for both professional and home audio setups.

One of the most notable features of the CM500i is its advanced driver configuration. It typically includes a high-performance 5.25-inch polypropylene woofer and a 1-inch tweeter, which work in harmony to produce a balanced frequency response. This design allows the speaker to handle a wide range of audio frequencies, ensuring that both deep bass and clear highs are accurately represented. The polycarbonate cabinet is specifically designed to minimize resonance, which contributes to clearer sound reproduction.

In terms of technology, the CM500i incorporates Phase Technology's unique "AcoustiSeal" technology. This innovative approach enhances the acoustic performance by providing an airtight seal around the woofer, which prevents air leaks and ensures that the sound produced is robust and undistorted. This technology, combined with the speaker's precision crossover network, allows for seamless transitions between the woofer and tweeter, resulting in a cohesive soundstage.

The CM500i also features a visually appealing design, making it a stylish addition to any audio setup. The speaker is available in a range of finishes, allowing users to choose a look that complements their home décor or recording studio. The front grille can be easily removed, giving the option to showcase the driver accents for a more modern aesthetic.

Portability is another advantage of the CM500i. Weighing in at a manageable size, it is easy to integrate into various environments, whether on stage, in a studio, or within a home audio system. The unit also includes versatile mounting options, making it adaptable to different listening environments.

Overall, the Phase Technology CM500i stands out in the crowded speaker market. With its cutting-edge driver technology, robust acoustic design, and user-friendly features, it offers an unbeatable combination of performance and style. Audio professionals and casual listeners alike will appreciate the quality and versatility that this speaker brings to their audio experience.
