but AD-518 Compression Driver – Precision High Frequencies
The AD-518 Compression Driver – Precision High Frequencies is a precision 1-inch throat driver, built to deliver crisp and powerful high-frequency audio. It offers exceptional efficiency, clarity, and long-term durability generally Ideal for use in PA systems, line arrays, fixed installations, and stage monitors, the AD-518 performs reliably even in the most demanding environments.
At the heart of the AD-518 is a 51.3mm (2-inch) copper-clad aluminum (CCAW) voice coil. This component provides excellent thermal conductivity and high efficiency. The driver supports 80W RMS power handling and up to 160W program power, making it capable of handling intense sound pressure levels. Despite as much as its power, it maintains tonal balance and clarity. With a sensitivity of 108 ± 2dB, it delivers strong output with minimal input—perfect for professional setups that demand maximum projection.
Its frequency response of 1200Hz to 20,000Hz ensures smooth, detailed reproduction across the high-frequency spectrum. The 1-inch (25.4mm) throat diameter and screw-on mounting design offer universal compatibility with a variety of horn flares and enclosures.
The AD-518 has an overall diameter of 134mm and weighs 2.5 kg. It is built for durability while still allowing easy integration into professional audio systems.
The diaphragm is crafted from pure titanium, known for its strength, light weight, and resistance to heat and fatigue. This material choice ensures exceptional transient response and consistent sound quality over extended use. The Strontium Ferrite Y35 magnet delivers strong magnetic flux and stable performance across the full frequency range. This ensures a powerful and dynamic output. Its rugged construction and reliable performance make it an excellent choice for rental systems, touring applications, and permanent installations.
FAQ Section
1. How does the 2-inch voice coil in the Audiotone AD-518 enhance high-frequency clarity?
Featuring a 51.3mm (2-inch) CCAW voice coil, the AD-518 provides enhanced power handling (80W RMS) and greater voice coil surface area compared to standard 1.75-inch drivers. This results in smoother mid-high vocal presence, improved thermal dissipation, and effortless high-frequency throw during loud live shows.
2. What horn lens mounting style does the AD-518 compression driver use?
Built with a standard 25.4mm (1-inch) throat diameter, this driver uses a screw-on mounting type. It threads directly onto standard 1-inch screw-mount horn flares, making it a versatile option for upgrading or replacing HF drivers in 2-way PA speakers and DJ tops.
3. How does the titanium diaphragm hold up under demanding stage environments?
The premium titanium diaphragm provides high structural rigidity and quick acoustic recovery, allowing it to reproduce bright, distortion-free highs. It ensures sharp vocal clarity and detailed treble response even when operated continuously at high output levels.
4. What crossover protection is recommended for this 80W RMS driver?
To safeguard the 2-inch CCAW voice coil from low-frequency strain, connect it through an active high-pass crossover or 2-way passive crossover network filtered between 1.5 kHz and 2.0 kHz (with a minimum slope of 12dB or 24dB/octave).
