TECHNICAL SPECIFICATIONS CB259X

COMPONENTS & CONSTRUCTION continued

15 mm void-free, gross-grain-laminated birch plywood. Extensive internal bracing is employed to minimize panel resonances resulting from the large acoustical energies generated within the enclosures.

The high frequency horn is constructed from a specially formulated compound which is non-resonant, lightweight and non-reflective.

The LF enclosure has 3 mounting points to allow optimum front/rear positioning of the HF component. The adjustable steel bracket attaching the HF horn to the LF enclosure allow the HF horn to be aimed independently at the LF section in both the horizontal and vertical planes and can be locked once it is positioned.

All components feature a textured black finish to eliminate the reflection of light through perforated cinema screens.

COMPONENTS & CONSTRUCTION

The CB259X is a two way, high-output, passive, full range loud- speaker system intended for use in cinema applications. It features dual 15-in low frequency transducers mounted in a vented enclosure and a titanium diaphragm compression driver mounted to a large, 2- in throat, 90°x40° coverage pattern, constant directivity horn.

The CB259X requires no external active electronic crossover. An internal passive crossover/filter network integrates the LF and HF sections. 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 input connector is a 2-terminal barrier strip located on the side of the LF section for convenient access in cramped installation areas. A jumper cable is provided to extend the signal chain to the HF component.

The low frequency enclosure is constructed of 3/4-in thick Medium Density Fiberboard (MDF) with the exception of the baffle which is

CB259X specifications

The EAW CB259X is a cutting-edge loudspeaker designed for professional audio applications, blending advanced technology with user-friendly features. This speaker is part of Eastern Acoustic Works' renowned line, known for its outstanding sound performance and durability, making it a preferred choice for concert venues, theaters, and events.

One of the standout features of the EAW CB259X is its two-way design that ensures optimal sound reproduction across a wide frequency range. The speaker is equipped with a high-output 15-inch LF (low-frequency) driver, which delivers deep, punchy bass that is essential for both music and vocal applications. Complementing the LF driver is a 1.4-inch compression driver mounted on a precision-engineered waveguide, providing exceptional clarity and presence in the higher frequencies.

The technology behind the CB259X includes a sophisticated crossover network that efficiently divides audio signals between the LF and HF drivers, allowing for smooth transitions and minimizing distortion. This ensures that listeners experience a balanced sound stage, whether in a loud concert or a quiet acoustic performance.

The EAW CB259X features a compact and portable design, making it convenient for transport and setup. Its rugged enclosure is constructed from high-quality plywood, finished with a durable coating that can withstand the rigors of touring and frequent use. Additionally, the speaker includes multiple rigging points, facilitating various mounting options for installation in different environments.

Versatility is another key characteristic of the EAW CB259X. It can be used in various configurations, whether as a standalone loudspeaker, in conjunction with subwoofers for enhanced low-frequency response, or as part of a larger line array system. This flexibility makes it suitable for a wide range of applications, from mobile DJ setups to permanent installations in clubs and auditoriums.

Furthermore, the CB259X is optimized for use with the EAW's proprietary alignment tools, ensuring that sound engineers can easily achieve the desired acoustic performance. The speaker's performance can be fine-tuned with the use of digital signal processing (DSP), providing users the ability to customize settings for specific venue requirements.

In conclusion, the EAW CB259X is a remarkable loudspeaker that combines high-quality sound, durability, and versatility. Its advanced technologies and thoughtful design make it an ideal solution for professionals seeking reliable audio performance in various settings. Whether for live events or permanent installs, the CB259X is engineered to meet the demands of contemporary audio requirements, solidifying its position as a top choice in the professional audio market.
