AD-44DE Compression Driver

The AD-44DE Compression Driver 1-inch throat compression driver designed for clear and powerful high-frequency audio. It is perfect for professional PA systems and sound reinforcement setups. Built for both efficiency and durability, the AD-44DE delivers consistent clarity across a wide frequency range. Its compact size also makes it ideal for portable setups without compromising performance.

At the core of the AD-44DE is a 44.4mm (1.75″) CCAW voice coil, offering superior conductivity and thermal stability. With an RMS power capacity of 80W, it delivers ample output while maintaining exceptional audio detail, even during extended use. The driver boasts an impressive sensitivity rating of 106 ± 2dB, ensuring high output levels with minimal power input — making it an excellent choice for stage monitors, portable PA systems, fixed installations, and compact horn arrays.

Covering a frequency response range of 800Hz to 16,000Hz, the AD-44DE ensures crisp and accurate reproduction of mid and high frequencies. This broad range allows it to handle vocals, cymbals, and other treble-rich content with exceptional clarity and presence.

The unit features a 25mm (1 inch) throat diameter and a standard bolt-on mounting design. This makes it compatible with a wide range of horn flares and enclosures. With an overall diameter of 115mm and a lightweight build of just 1.62 kg, it integrates easily into both portable and fixed systems. Despite its compact size, it delivers powerful performance without compromise.

The diaphragm is made from durable PEN (Polyethylene Naphthalate), a material known for its stiffness-to-weight ratio and fatigue resistance. This ensures long-term reliability in high-performance applications. The driver is paired with a Strontium Ferrite Y35 magnet, which delivers stable magnetic flux and excellent dynamic response. This combination makes the AD-44DE ideal for demanding live sound environments.

Available in 8Ω and 6Ω impedance variants, this driver gives system designers the flexibility to match amplifier and speaker configurations with ease.

Whether you’re building a new sound system or upgrading your high-frequency components, the AD-44DE offers the perfect balance of performance, efficiency, and reliability.

FAQ Section

1. What makes the PEN diaphragm in the Audiotone AD-44DE suitable for high-frequency audio?

The driver utilizes a Polyethylene Naphthalate (PEN) diaphragm, which combines lightweight agility with high structural stability. This material offers exceptional damping properties, reducing high-frequency harshness and delivering smooth, natural-sounding vocal and treble reproduction up to 16 kHz.

2. What sound system setups are ideal for this 80W RMS compression driver?

With an 80W RMS power rating and a high sensitivity of 106 dB, the AD-44DE is tailored for 2-way PA cabinets, stage monitor wedges, and compact line arrays. It delivers clear vocal projection and crisp top-end detail that cuts through live sound mixes and DJ environments cleanly.

3. What horn lens mounting configuration does the AD-44DE require?

This driver features a standard 25mm (1-inch) throat diameter with a bolt-on mounting pattern. It pairs smoothly with standard 1-inch exit horn waveguides to ensure controlled high-frequency dispersion across your audience coverage area.

4. What crossover frequency is recommended to protect the 1.75-inch CCAW voice coil?

Given its wide frequency response starting at 800Hz, configuring an active or passive high-pass crossover filtered between 1.2 kHz and 1.8 kHz (with a minimum slope of 12dB or 24dB/octave) prevents low-frequency strain and maximizes diaphragm life.
