TECHNICAL SPECIFICATIONS CB259X

APPLICATION

For medium cinemas

Passive 2-way screen channel loudspeaker

Requires only one amplifier channel and no external crossover

PRODUCT INFORMATION

The CB259X two-way passive screen loudspeaker system fills medi- um-sized theaters with all the high-impact, full-range sound encoded on today’s digital soundtracks while reproducing voices clearly and naturally.

The two component system includes a BV253C vented dual 15-in low frequency unit and a HK294 high frequency system - a medium for- mat 90°x40° HF horn loading a large diaphragm 2-in exit compression driver.

The HK294’s constant directivity horn assures even distribution of high frequency information to every seat in the house. Its shortened horn throat minimizes horn throat distortion, eliminating the 700 Hz “honk” that has plagued cinema HF horns.

The BV253C’s optimally vented enclosure uses the enclosure’s reso- nance to increase LF response while limiting driver excursion. This method produces less distortion and minimizes driver strain while extending LF response to the lowest octaves.

The sections are integrated via an internal passive crossover/filter network. 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 adjustable steel bracket attaching the HF horn to the LF enclo- sure can be positioned at one of three mounting points for optimum front/rear HF horn placement. The bracket 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.

The LF section includes a barrier strip that accommodates bare wire, tinned leads or spade lugs. A jumper cable is supplied to extend the signal chain to the HF component. The input connector is located on the side of the enclosure for convenient access in cramped installa- tion areas. HF component connection is made directly on the compression driver.

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.
