AD-551XLS Compression Driver – High-Output Precision

The AD-551XLS Compression Driver – High-Output Precision is a robust and high-efficiency 1-inch throat compression driver, designed to deliver powerful, detailed, and reliable high-frequency performance across a wide range of professional audio applications. Whether you’re building a premium PA system, configuring line arrays, or upgrading your stage monitoring setup, the AD-551XLS offers the clarity, control, and durability that professionals demand.

At its core, the AD-551XLS is powered by a 51.3mm (2-inch) copper-clad aluminum (CCAW) voice coil as can be seen This component offers excellent thermal conductivity and high efficiency. It ensures stable, distortion-free output even at high volume levels. The AD-551XLS supports 100W RMS power and up to 200W program power, making it ideal for demanding sound reinforcement tasks. Its 108 ± 2dB sensitivity rating delivers strong output with minimal power input—perfect for large venues and high-SPL environments.

The frequency response range of 800Hz to 16,000Hz covers a broad high-frequency spectrum. This allows the AD-551XLS to reproduce vocals, instruments, and effects with precision and accuracy.

Whether you’re pushing mids or crisp treble content, it delivers with confidence.

The AD-551XLS features a 25mm (1-inch) throat diameter and a screw-on mounting type, allowing for easy integration with various horn flares and enclosures. It has an overall diameter of 134mm and weighs 2.7 kg. This offers a stable, solid structure while keeping the weight manageable for both portable and fixed sound systems.

A major highlight of the AD-551XLS is its composite diaphragm, engineered to balance strength, responsiveness, and fatigue resistance. This material helps maintain sonic consistency over time, even in high-demand applications. Paired with a Strontium Ferrite Y35 magnet, the driver generates strong magnetic flux for enhanced sensitivity and dynamic range.

Available in 8Ω and 6.5Ω impedance options, the AD-551XLS gives system designers flexibility in configuration and amplifier matching.
