Architectural Specifications

The loudspeaker shall consist of a 133

mm(5.25 in) low-frequency transducer and a 25 mm (1.0 in) high-frequency transducer with a crossover network installed in the enclosure. The low-fre- quency voice coil diameter shall be 25 mm (1.0 in).

Performance specifications of a typi- cal production unit shall be as follows: Useable frequency response shall extend from 55 Hz – 22 kHz (-10 dB, half space, no external equalization). Measured sensitivity (2.83 Volt input, 1 meter) shall be at least 88.5 dB. The speaker

shall have a nominal impedance of 8 Ohms and be available for 25, 70.7 & 100 Volt modes with voice coil/8 Ohm direct. The frequency-dividing network shall have a crossover frequency of 3 kHz with slopes of 12 dB per octave (2nd order) for both low & high pass filters. Rated power capacity shall be at least 75 Watts continu- ous power (RMS) and conform to EIA-426- B testing. Maximum continuous output at 1 meter shall be 107.5 dB.

The low-frequency transducer shall have a polypropylene cone with rubber surround. The high-frequency transducer shall be constructed of aluminum with a proprietary BroadBeam® waveguide.

Installation for the CM500i shall be by 2-screw, blind-mount, constant tension winged assembly and shall attach to ceil- ing thickness tolerances ranging from

6.4mm (0.25 in) to 42.9 mm (1.69 in). The fixed-wing assembly shall be constructed of glass-filled ABS material. The external wiring input connector shall be a 4-pin,

5 mm Euroblock for 8 Ohm or distributed systems and shall accept from 10 – 22 gauge wire.

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. The CM500i truly exemplifies Phase Technology's dedication to innovation and excellence in sound reproduction.
