Technical Specifications CB423MX

CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CB423MX is a biamplified (passive mid/high) three-way, high- output, full range loudspeaker system intended for use in behind- screen cinema applications. The two component system includes a BV423 15-in low frequency enclosure and an HK523MX 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 an internal passive crossover/filter network with the crossover set at 1.43 kHz integrated via a complex passive crossover/ filter network. EAW's computer-designed passive filter networks are tightly aligned to the loudspeakers they control and go beyond merely dividing the signal, performing critical equalization func- tions.

The BV423 low frequency component features a single 15-in woofer mounted in a vented enclosure for excellent bass extension and high output level capability.

The HK523MX mid/high component features a horn-loaded 10-in midrange driver and a 1.4-in exit compression driver mounted to a medium format 90° x 45° constant directivity horn.

Input connectors for both the LF and mid/high components are 2- terminal barrier strips that accommodate bare wire, tinned leads or spade lugs. Separate input connectors are provided for the LF and mid/high components. A pre-installed "jumper cable" continues the signal chain to the HF section.

The LF cabinet is constructed of 3/4-in Medium Density Fiberboard (MDF). The HK523MX mid/high section is constructed of 3/4-in MDF with the exception of the mid frequency flare which is void-free, 18- ply-to-the-inch, Baltic birch plywood backed with high density polyurethane foam. Both sections are coated with a non-reflective, textured black finish and the HF horn is constructed of flat black structural foam plastic.

Coupled with a 1.4-inch neodymium HF compression driver, the speaker offers crystal-clear highs, resulting in a well-rounded sound profile. The carefully tuned crossover network seamlessly blends the low and high frequencies, allowing for a smooth audio experience that is ideal for both live music and speech applications.

The cabinet construction of the CB423MX employs high-quality plywood, providing both rigidity and durability. This allows the speaker to withstand the rigors of transport and repeated use while maintaining acoustic performance. The finish is scratch-resistant, and the design includes multiple rigging points, making it easy to integrate into various setups, whether flown or ground-stacked.

EAW's proprietary technologies enhance the overall performance of the CB423MX. The speaker is equipped with advanced thermal management systems to prevent overheating, ensuring reliability even during extended use. Additionally, the speaker's dispersion pattern is meticulously designed to deliver consistent sound coverage across large areas. This makes it particularly effective in larger venues where uniform sound distribution is essential.

Connectivity options are simplified with integrated speakON and binding post connectors, allowing for easy integration with other audio components. The CB423MX is also actively supported by EAW's software tools, providing real-time monitoring and measurement capabilities for sound engineers.

In summary, the EAW CB423MX is designed for professionals who demand high fidelity, versatility, and durability in their audio systems. Its combination of powerful drivers, robust construction, and user-centric features makes it a valuable asset for anyone seeking reliable sound reinforcement solutions in diverse environments.
