DH2T-8/DH2T-16

2-Inch High Frequency

Transducer

Key Features:

Pure titanium dome provides extended high frequency response

Lightweight aluminum voice coil for maximum efficiency

Unique convex-drive phase plug

1-3/8” screw on connection

Available in 8 and 16 ohms

General Description:

The Electro-Voice DH2T high frequency compression driver is capable of high acoustic output over a wide frequency range. Precise engineering, along with careful selection of materials and advanced driver architecture, has resulted in a driver that is ideally suited for the most demanding presentation of high quality music and communications program.

Incorporating Electro-Voice’s exclusive Ring Mode Decoupling (RMD) through all design phases has produced drivers with unmatched accuracy while minimizing any acoustic resonances, or time domain ringing throughout the driver structure.

Years of dedicated research and experience in the field have yielded a new high performance solution for use in both two and three-way systems, as well as demanding stand alone horn applications

A unique, geometrically optimized 2" titanium diaphragm, consisting of a one piece dome and suspension structure, gives these drivers an ideal combination of superb high frequency response and resistance to fatigue. The DH2T provides smooth response from 800-20,000 Hz.

DH2T-8, DH2T-16 specifications

The Electro-Voice DH2T-16 and DH2T-8 are notable compression drivers designed for professional sound reinforcement applications. These drivers are distinguished by their advanced engineering and robust construction, making them suitable for a wide variety of audio settings, from concert venues to permanent installations.

One of the standout features of these models is their exceptional performance across a broad frequency range. The DH2T-16 is optimized for 16-ohm systems, while the DH2T-8 caters to 8-ohm setups. Both models deliver high output levels with low distortion, ensuring that vocal clarity and instrument detail are preserved even at high volumes. Their ability to reproduce sound accurately makes them ideal for use in demanding environments where audio fidelity is crucial.

Another key characteristic of the DH2T series is the incorporation of a titanium diaphragm. This material is known for its durability and ability to handle high power levels, contributing to the longevity of the drivers. The diaphragm's design, combined with an optimized phase plug, allows for efficient sound wave propagation, resulting in a smooth frequency response and reduced feedback.

Both models feature a compact and lightweight design, making them easy to integrate into existing systems or to mount in various configurations. Despite their small size, they deliver impressive acoustic power, making them a preferred choice for many sound professionals.

The heat resistance of the DH2T compression drivers is enhanced by their thermal management technology, which dissipates heat effectively. This feature helps maintain performance stability during prolonged use, preventing any degradation in sound quality or driver performance.

Electro-Voice has also incorporated advanced magnetic structures in these models. The high-performance neodymium magnet facilitates a strong magnetic field, which boosts efficiency and output. This technology not only results in a lighter driver but also ensures robust power handling capabilities.

In summary, the Electro-Voice DH2T-16 and DH2T-8 compression drivers represent a fusion of cutting-edge technology and practical design. With their titanium diaphragm, efficient magnetic structure, and robust build quality, these drivers offer unparalleled performance for professional audio applications. Their versatility, sound quality, and durability make them a trusted choice for audio engineers and sound system designers worldwide.
