High-Efficiency 1.5″ Dual Diaphragm Neodymium Compression

Engineered for precision and power, this High-Efficiency 1.5″ Dual Diaphragm Neodymium Compression is a top-tier component for professional audio applications where high-frequency clarity, reliability, and efficiency are essential. Designed for use in line arrays, concert speakers, theater systems, and premium PA cabinets, it offers outstanding performance in a compact and durable form.

Powerful Output with Dual Coil Efficiency

The driver is equipped with two 76.2mm voice coils, delivering a combined AES power handling of 160W (2×80W above 1000Hz). This ensures excellent thermal capacity and reduced distortion at high output levels. It delivers a maximum SPL of 110dB at 60W, while offering impressive sensitivity figures—105dB at 2×1W/1m and 102dB at 1W/1m/2.83V. As a result, it produces powerful output with minimal amplifier load, making it ideal for energy-efficient systems.

Precision Across the High-Frequency Range

Covering a wide frequency range from 1000Hz to 20,000Hz, this driver ensures accurate reproduction of vocals, cymbals, strings, and effects. Whether used for lead vocals or high-frequency instrument detail, it ensures clarity and definition across the upper frequency spectrum.

High-Grade Components for Superior Durability

The compression driver features a Kapton voice coil former, known for its excellent heat resistance and mechanical stability. The polyester diaphragm offers lightweight strength and delivers detailed sound reproduction. A Neodymium N50 SH magnet generates a powerful flux density of 1.95 Tesla, enabling high output in a compact form. This advanced magnet also reduces the unit’s weight to just 2.2 kg, making it perfect for portable or flyable systems.

Installation Flexibility and Build Quality

The driver features a 38mm (1.5-inch) throat diameter with a 4x M6 bolt pattern at 90° on an 82.5mm circle. This ensures secure mounting and broad compatibility with various horns and enclosures. Whether you’re upgrading a touring rig or designing a new speaker, this driver provides consistent, high-performance audio output.
