The DE-2501 is a compact, versatile compression driver designed for professional and commercial audio applications where clarity, flexibility, and ease of integration are the primary requirements. With a 1-inch throat and a choice of titanium or phenolic diaphragm materials, this driver offers system designers the freedom to tailor tonal characteristics to specific application needs while maintaining reliable, high-quality performance.
Flexible Diaphragm Options
The availability of both titanium and phenolic diaphragm materials gives users the ability to optimize the driver's signature. The titanium option delivers crisp, detailed highs with excellent transient response, while the phenolic variant offers a smoother, more natural midrange character with enhanced damping - ideal for applications where vocal warmth and reduced harshness are prioritized.
Round Copper or Aluminium Voice Coil
The 1-inch (25.4mm) voice coil is available with either round copper or aluminium wire, allowing further customization of performance characteristics. Copper wire provides excellent conductivity and smooth frequency response, while aluminium wire reduces moving mass for improved transient response and extended high-frequency reach.
Efficient Performance
With a sensitivity of 106 dB (1W/1M), the DE-2501 produces strong output with modest power input, making it an efficient solution for systems where amplifier headroom may be limited or where energy efficiency is a priority.
Compact Neodymium Motor
The N-38 grade neodymium magnet generates a flux density of 1.35 Tesla in a remarkably compact form factor. This high-strength, lightweight magnetic structure ensures accurate diaphragm control and low distortion while keeping overall driver weight to a minimum - a significant advantage in space-constrained installations.
Standard Screw-On Mounting
Featuring a 1 3/8" screw-on mounting interface, the DE-2501 is compatible with a wide variety of standard horns and waveguides, simplifying system integration and replacement.
The DE-2501's compact size, flexible configuration options, and reliable performance make it well-suited for a broad spectrum of audio applications:
Compact Portable PA Systems - Ideal for small to mid-sized mobile sound systems used by DJs, musicians, and event organizers who need lightweight, easy-to-transport equipment.
Fixed Installation Venues - Perfect for restaurants, bars, retail spaces, conference rooms, classrooms, and houses of worship where clear, consistent sound reinforcement is needed without complexity or excessive cost.
Stage Monitors and Wedges - The detailed midrange and high-frequency response ensures performers can hear vocals and instruments with clarity on stage, helping them deliver their best performance.
Distributed Sound Systems - The efficient design and standard mounting make it an excellent choice for multi-zone commercial audio systems in offices, hotels, shopping malls, and public spaces.
Background Music and Paging Systems - The flexible diaphragm options allow system designers to choose between bright, articulate highs (titanium) or warmer, more natural tones (phenolic) depending on the environment.
Compact Line Arrays and Column Speakers - The small form factor allows seamless integration into slim, modular array designs for distributed sound coverage in venues of all sizes.
OEM and Custom Speaker Projects - The flexible diaphragm and voice coil options make this driver an excellent choice for custom speaker builders and OEM integrations.
Rated at 20 Watts RMS with an 8 Ohm nominal impedance, the DE-2501 is engineered for applications where clarity, compactness, and configurability matter more than raw power output. The combination of a 1-inch throat for precise acoustic coupling and a lightweight neodymium motor structure makes it an ideal solution for modern audio systems that demand high performance in a small footprint.
Whether you need the bright, articulate character of a titanium diaphragm or the warm, natural tonality of phenolic, the DE-2501 delivers professional-grade high-frequency performance in a package that is as flexible as it is reliable.
