AD-4591 2″ Ferrite Compression Driver

The AD-4591 2″ Ferrite Compression Driver is a robust and precision-engineered designed for professional audio systems requiring exceptional output, clarity, and efficiency. Built to deliver high sound pressure levels with minimal distortion, this driver is perfect for large venue PA systems, touring rigs, line arrays, and installations where reliability and performance are critical.

Powerful Performance with Extended Frequency Response

The AD-4591 delivers a peak power handling capacity of 1000W (above 500Hz). It offers a wide frequency response of 200Hz to 9000Hz. This makes it ideal for applications such as vocal clarity, instrument definition, and ambient sound projection. Whether you’re reinforcing speech or music, the AD-4591 offers consistent performance and acoustic detail.

High Sensitivity and Magnetic Strength

This driver boasts a sensitivity of 118dB (1W/1m on 2242 horn), ensuring efficient sound production even at low input levels. The ferrite magnet produces a strong flux density of 1.95 Tesla. This helps the driver perform efficiently across its full frequency range. With an efficiency rating of 35% between 300Hz and 5000Hz, the AD-4591 stands out for its excellent power-to-output ratio.

Durable Materials for Long-Term Use

Internally, the AD-4591 uses a 3.5-inch copper-clad aluminum voice coil wound on a Kapton former, offering high thermal resistance and consistent operation under high loads. The polyester diaphragm is lightweight yet durable, contributing to the driver’s clear and precise sound reproduction over long-term use.
