B&C Speakers DE 700 TN

A B&C Compression Driver Designed for Stage and Installation

The DE 700 TN fits within B&C's approach: offering loudspeaker components intended for professional sound reinforcement, where consistency and power handling are paramount. This high-frequency driver aims for natural integration into horn-loaded speakers, whether for a two-way speaker, a multi-amplified system, or a fixed installation setup. With its ferrite magnet and performance-oriented design, it meets the typical needs of speaker manufacturers, contractors, and technicians seeking a directional, clear high-frequency driver capable of long-term stability.

Who Is the B&C DE 700 TN For?

This high-frequency driver is intended for users who design, repair, or optimize sound reinforcement speakers: repair workshops, integrators, manufacturers, or knowledgeable musicians and technicians working with horn systems. It is particularly suitable when a high-frequency driver that "carries" sound throughout the venue is expected, with good intelligibility and a comfortable margin for live use (vocals, guitars, keyboards, DJs, stage monitors) or installations (bars, clubs, multipurpose venues). Its recommended crossover frequency at 0.8 kHz allows for a relatively low crossover point for a high-frequency driver, provided filtering and system tuning are appropriately managed.

Performance and Design: Precision, Efficiency, and Power Handling

Frequency Response and Crossover

With a frequency response specified from 0.5 to 18 kHz, the DE 700 TN covers a wide useful range for high-frequency reproduction. The manufacturer recommends a crossover frequency of 0.8 kHz: this is an important reference for choosing the cutoff frequency and ensuring reliable operation in a horn-loaded speaker. In practice, the optimal setting will also depend on the horn used, the filter slope, and the overall system calibration.

Power and Efficiency

The driver is rated for 110 Watts nominal power and 220 Watts program continuous power. Combined with a sensitivity of 107.5 dB, this makes it an efficient transducer capable of producing a high sound level with moderate amplifier demand. This balance is sought after in sound reinforcement, as it provides headroom and limits the perception of "strained" highs when the system is pushed.

Materials: Titanium Diaphragm, Aluminum Voice Coil

The titanium diaphragm aims for clear and detailed reproduction, while the aluminum voice coil (75 mm diameter) contributes to thermal behavior and dynamic response. The stated flux density of 1.9 T emphasizes the "motor" focus of this model, designed to maintain impact and definition, especially on transients (vocal attacks, harmonic clarity, instrument articulation).

Maintenance and Parts Availability

For a speaker fleet, maintenance capability is a real advantage. The DE 700 TN offers a replacement diaphragm referenced MMD3ATN8, convenient for quickly restoring a driver to service while maintaining the system's sonic coherence.
