Product Overview
The DE-4403TS-2 is a high-power 1-inch compression driver engineered for the most demanding professional audio applications. At its core is an oversized 44.4 mm (1.75 in) voice coil - one of the largest in its class - combined with a high-flux 1.75 T Y35 strontium ferrite magnet structure. This design delivers 50 Watts RMS power handling and 107 dB sensitivity, producing effortless, high-SPL output with remarkable clarity and low distortion from 1.2 kHz to 20 kHz.

Key Advantages
• Class-leading 44.4 mm voice coil - exceptional power handling and superior thermal dissipation for sustained high-output operation.
• High sensitivity (107 dB) - achieves maximum SPL with lower amplifier drive, improving overall system efficiency.
• Titanium diaphragm - delivers crisp, natural high frequencies with outstanding stiffness-to-weight ratio.
• Round & ribbon aluminium voice coil wire - optimises heat transfer and ensures fast, accurate transient response.
• High flux density (1.75 T) with Y35 magnet - produces a strong, stable magnetic field for consistent, repeatable performance.
• Extended low-end crossover (1.2 kHz) - enables flexible multi-way system design with seamless driver integration.
• Dual mounting (screw-on 1 3/8″ / bolt-on) - compatible with a wide range of industry-standard horns and waveguides.
• Rugged construction - built to withstand the rigours of touring, outdoor events, and long-term fixed installation.

Typical Application Scenarios
▸ Large-Scale Concerts & Festivals
   Capable of cutting through dense, high-SPL mixes at long throw distances, making it ideal for outdoor stages, arena tours, and festival main PA systems.

▸ Professional Touring Line Arrays
   The oversized voice coil and robust thermal design ensure reliable, consistent performance night after night under the most demanding touring conditions.

▸ High-Output Fixed Installations
   Perfect for large houses of worship, sports arenas, convention centres, and theatres where long-term reliability and high-fidelity HF reproduction are essential.

▸ Premium Active & Passive Loudspeakers
   An excellent HF engine for two-way or three-way speaker designs, offering system designers the flexibility of a 1.2 kHz crossover point.

▸ Stage Monitors & Side-fills
   Provides performers with accurate, detailed high-frequency feedback on stage, maintaining clarity even at high monitoring levels.

▸ DJ, Nightclub & Dance Music Systems
   Handles high-energy programme material with authority, keeping the top end crisp, articulate, and fatigue-free during extended playback at elevated volumes.

▸ Broadcast & Cinema Monitoring
   When paired with the appropriate waveguide, it offers the smooth, extended high-frequency response required for critical listening in post-production and broadcast environments.
