Technical Specifications CB152

CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CB152 is a two way, high-output, full range loudspeaker system intended for use in behind screen applications. It features a 15-in low frequency transducer mounted in a compact, vented enclosure and a titanium diaphragm compression driver mounted to a large diaphragm, 1.4-in throat, 90° x 90° coverage pattern, constant directivity horn.

The CB152 requires an external active electronic crossover. The recommended crossover point is 1200 Hz. Input connectors for the HF section are dual spring loaded push-button type, designed to accommodate bare or tinned leads, with a 2-terminal barrier strip for the LF section.

The low frequency enclosure is constructed of 3/4-in thick Medium Density Fiberboard. Extensive internal bracing is employed to minimize panel resonances resulting from the large acoustical energies generated within the enclosures. The enclosure and all external parts are coated with a black finish.

The high frequency horn is constructed from a specially formulated structural polyurethane foam which is non-resonant, lightweight and non-reflective. The LF enclosure has 2 mounting points on both top and bottom to allow optimum front/rear positioning of the mid/ high component for either right or left channel. The adjustable steel bracket attaching the HF horn to the LF enclosure allows the HF horn to be aimed independently of the LF section in both the horizontal and vertical planes and can be locked once it is positioned.

CB152 specifications

The EAW CB152 is a remarkable loudspeaker system that exemplifies the advanced engineering and sound reproduction capabilities of Eastern Acoustic Works (EAW). Designed as a compact yet powerful solution for various sound reinforcement applications, including live events, permanent installations, and corporate environments, the CB152 stands out with its blend of versatility, reliability, and high-quality audio performance.

One of the main features of the EAW CB152 is its dual 15-inch low-frequency drivers, which deliver substantial bass response and high output levels. This is particularly beneficial for applications that demand impactful low-end presence, such as concerts and DJ performances. The integration of a specialized high-frequency compression driver ensures that the mid and high frequencies remain clear, crisp, and well-defined, allowing for a balanced sound across all frequency ranges.

The CB152 incorporates advanced technologies that enhance its performance. EAW's proprietary Dynacord technology is utilized, which optimizes the loudspeaker's sensitivity and efficiency, allowing it to produce higher sound levels with minimal distortion. This translates to a loudspeaker that not only sounds great at high volumes but also maintains audio fidelity during prolonged use.

The enclosure of the CB152 is constructed from durable plywood and features a rugged finish, designed to withstand the rigors of both mobile and installed applications. The cabinet's design is carefully tuned to minimize unwanted resonance, further enhancing the overall sound quality. Additionally, a built-in rigging system facilitates easy mounting and transport, making it a practical choice for those on the go.

In terms of connectivity, the EAW CB152 offers multiple input options, allowing for various signal types to be used seamlessly. This flexibility makes it a suitable choice for diverse audio setups, whether in a small venue or a large outdoor event.

In conclusion, the EAW CB152 loudspeaker system is characterized by its impressive sound quality, robust build, and advanced technologies. Its combination of dual 15-inch drivers, high-frequency compression technology, and practical design make it a versatile choice for professionals seeking a powerful and reliable sound reinforcement solution. Ideal for a multitude of applications, the CB152 continues to set a high standard in the audio industry.
