Technical Specifications CB153

CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CB153 is a compact, biamplified (passive mid/high), three-way, high-output, full range loudspeaker system intended for use in behind-screen cinema applications. The two component system consists of a BV154C low frequency enclosure and an HK153 passive mid/high system.

The system requires the use of an external active electronic crossover between the LF and mid/high sections with a maximum recommended crossover point of 350 Hz. The mid/high component includes a internal passive crossover/filter network with the cross- over set at 1.8 kHz. EAW's complex, computer-designed passive filter networks are tightly aligned to the loudspeakers they control and go beyond merely dividing the signal, performing critical equalization functions.

The BV154C low frequency component features a single 15-in low frequency driver mounted in an asymmetrical, vented enclosure for excellent bass extension and high output level capability with low distortion.

The HK153 mid/high component features a 1-in exit compression driver loaded with EAW’s proprietary WGP® (Wave Guide Plate) and a direct radiating 8-in mid frequency cone transducer.

The LF cabinet is constructed of 3/4-in Medium Density Fiberboard (MDF) with the exception of the baffle, which is constructed of 15mm void-free, 18-ply-to-the-inch Baltic birch plywood. The mid/ high enclosure is constructed entirely of the MDF. Extensive internal bracing is provided for both the LF and mid/high sections to minimize panel resonances resulting from the large acoustical energies generated within the enclosure while maximizing acousti- cal energy transfer into the audience area. The enclosures and all external parts are coated with a textured black finish.

Input connectors for both the LF and mid/high sections are 2- terminal barrier strips. Separate input connectors for the LF and mid/high sections are located on the side of the enclosure for convenient access in cramped installation areas.

The adjustable steel bracket attaching the mid/high component to the LF enclosure allows the mid/high section to be aimed indepen- dently of the LF section in both the horizontal and vertical planes and can be locked once it is positioned. The LF enclosure has 2 mounting points to allow optimum front/rear positioning of the mid/high component.

CB153, CINEMA Series specifications

The EAW CINEMA Series, specifically the CB153 model, represents a significant advancement in cinema audio technology, designed to enhance the auditory experience in commercial theatres and venues seeking exceptional sound quality. This high-performance loudspeaker is engineered to deliver superior clarity and power while maintaining fidelity across a range of frequencies, ensuring that every detail of a film's audio is presented accurately.

One of the main features of the CB153 is its three-way design, which includes a 15-inch low-frequency woofer, dual 6.5-inch midrange drivers, and a 1.5-inch compression driver. This configuration allows the system to effectively reproduce a wide spectrum of sound, from deep bass to crisp highs, making it perfect for cinematic applications where dialogue, effects, and music must be delivered with precision.

The CB153 utilizes advanced technologies like the patented EAW Focusing which allows the system to optimize the frequency response. This technology helps in creating a more uniform sound field throughout the theatre, ensuring that every seat receives an equally immersive audio experience. Adding to its effectiveness is the use of a sophisticated passive crossover network that minimizes phase distortion, providing an even clearer soundstage.

In terms of build quality, the CB153 is designed with durability in mind. Its robust construction includes high-quality materials that can withstand the rigors of high-performance environments. The loudspeaker is also finished with a sleek, professional appearance that can seamlessly blend into various cinema designs.

Yet another defining characteristic of the CB153 is its versatility in deployment. It can be used in a variety of configurations, whether in arrays for larger auditoriums or as standalone units in smaller spaces. This adaptability makes it a valuable asset for theatres looking to customize their audio setup based on specific requirements or venue acoustics.

Connectivity options further enhance its appeal, featuring options that allow for easy integration into existing sound systems. With its combination of innovative technologies and thoughtful design, the EAW CINEMA Series CB153 stands out as a top choice for venues aiming to deliver an unmatched cinematic audio experience. Whether it's for blockbuster films or intimate screenings, the CB153 ensures that every audience member is transported into the heart of the story.
