B&C DE250 – 1″ High-Efficiency Compression Driver

The DE250 by B&C Speakers is a premium 1-inch exit compression driver engineered for professional sound reinforcement where clarity, power, and smooth wide‑band performance are crucial. Featuring a polyimide diaphragm, optimized aluminium voice coil, and efficient ferrite motor, the DE250 delivers precise, high‑output audio from 1 kHz up to 18 kHz.

Developed in Italy, the DE250 offers consistent acoustic performance and rugged reliability, making it a preferred choice for horn-loaded systems, coaxial setups, and high‑efficiency PA installations.

Consistent, Controlled High-Frequency Performance

The DE250 is built around a 44 mm (1.7 in) aluminium voice coil paired with a polyimide diaphragm. This combination provides clean, distortion‑resistant HF reproduction with excellent thermal behaviour under continuous use. The driver yields a frequency range of 1 kHz to 18 kHz, ensuring vocal and treble detail are delivered with accuracy and consistency across diverse program material.

Power Handling and Integration Flexibility

Rated for 60 W nominal power handling and 120 W continuous program power, the DE250 is capable of sustaining high output with headroom for dynamic peaks. Ideal for high‑efficiency systems, compact tops, and distributed loudspeaker setups, it performs reliably without thermal compression or performance loss.

Efficiency and Compatibility

The DE250 has a nominal impedance of 8 Ω with a minimum impedance of 7.8 Ω, making it broadly compatible with common amplifier configurations. With a sensitivity of 108.5 dB (1W/1m), it offers high acoustic output with minimal amplifier drive, boosting overall system efficiency in demanding sound reinforcement scenarios

Compact Form Factor, Wide Utility

Its compact motor and throat design suit horns and waveguides designed around a 25 mm (1 in) throat diameter, achieving smooth coupling without excessive bulk. With its optimized materials and precise build, the DE250 integrates cleanly into coaxial systems, compact speakers, and horn-loaded tops where space is limited.

Performance Overview

The DE250 combines efficient thermal engineering with a high‑output diaphragm design to deliver controlled highs with minimal distortion. Whether used in horn‑loaded mid/high speakers, coaxial or direct‑radiating setups, the DE250 excels at delivering intelligible vocals and crisp treble in both music and speech applications.

Its high sensitivity means lower amplifier demands for a given SPL, ideal for distributed systems, fill loudspeakers, or mid‑sized PA systems where power efficiency affects the overall system cost and acoustic performance.

Applications

Touring Systems: With its robust power handling and clean output, the DE250 is a strong choice in live sound rigs and powered column systems, especially where weight and reliability matter.
Compact Passive Cabinets: Excellent for horn‑loaded top boxes or coaxial designs built around 1″ throat drivers, the DE250 allows small-format enclosures to deliver clarity and presence.
Installations: Ideal for fixed installations in clubs, houses of worship, or venues with limited HF driver space but high intelligibility demands.
OEM Speaker Builds: Manufacturers designing lightweight, high-efficiency yet small‑profile products benefit from the DE250’s mechanical simplicity and reliable performance.

Conclusion

The DE250 is engineered to offer precision, reliability, and high acoustic efficiency in a compact compression driver format. Its aluminium voice coil, polyimide diaphragm, and effective thermal design deliver smooth response, low distortion, and consistent output across its 1 kHz–18 kHz range.

For designers and engineers needing a robust, high‑efficiency 1″ driver that integrates cleanly into coaxials, horns, or compact passive systems, the DE250 delivers the sonic clarity, durable build, and performance headroom required in professional environments.

When clarity, efficiency, and compact form factor are priorities—DE250 is the go‑to driver.
