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.
