405-4T, 405-8H specifications

Electro-Voice is well-regarded in the audio industry for its innovation and quality, and the Electro-Voice 405-8H and 405-4T drivers are prime examples of the brand's commitment to delivering superior sound reproduction. The 405-8H and 405-4T are high-performance compression drivers designed to meet the demands of professional audio applications, including live sound reinforcement and installed sound systems.

The Electro-Voice 405-8H features an impressive 8-ohm impedance, making it compatible with a variety of amplifiers. With a power handling capacity of 250 watts, this driver can deliver excellent sound pressure levels without compromising clarity. The 405-4T, on the other hand, operates at a lower impedance of 4 ohms, which allows for increased power handling, reaching up to 400 watts. This makes the 405-4T particularly suitable for applications where maximum efficiency and output are paramount.

Both models utilize advanced neodymium magnet structures, which contribute to their lightweight design while maintaining high efficiency. This characteristic is especially important for touring applications where weight can significantly impact transportation and setup times. The neodymium magnets also enhance the drivers' magnetic flux, resulting in improved responsiveness and overall performance.

One of the standout features of the 405 series is the patented phase plug design. This technology minimizes phase distortion, ensuring that the sound remains true to the original source across all frequencies. Coupled with a high-frequency response that extends to 20 kHz, these drivers excel in delivering clear, articulate sound even in challenging acoustic environments.

The diaphragm construction is another area where the Electro-Voice 405 drivers shine. They utilize a lightweight yet durable diaphragm material that ensures high sensitivity and quick transient response. This results in a sound output that is both dynamic and detailed, perfect for crisp vocals and intricate instrumentals.

Furthermore, the 405-8H and 405-4T are designed with versatility in mind. They can be integrated into a wide range of cabinets and configurations, making them suitable for various applications, from large concert systems to smaller events. Their robust construction also ensures long-lasting durability, allowing for consistent performance in rigors of touring or permanent installations.

In summary, the Electro-Voice 405-8H and 405-4T drivers represent the culmination of advanced technology and quality craftsmanship. With features such as neodymium magnets, phase plug design, and durable diaphragm materials, they deliver unparalleled sound quality and reliability, making them a top choice for audio professionals worldwide.
