The DE-4402, also designated DE-160, is a high-capacity 1-inch compression driver that pairs an oversized 44.4 mm voice coil with a polyimide diaphragm for a unique combination of thermal muscle and smooth, controlled highs. Delivering 106 dB sensitivity and a robust 60 watts RMS power rating across a wide 1.2 kHz - 20 kHz bandwidth, it is built for applications that demand both output and refinement.
The engineering story of the DE-4402 centres on its 44.4 mm (1.75 in) voice coil - among the largest in any 1-inch exit driver. This massive coil spreads thermal energy across a vast surface area, allowing the driver to sustain high SPL output for extended periods without power compression or thermal degradation. The coil is wound with ALR pure aluminium wire - a flat-ribbon conductor that maximises fill factor, reduces moving mass, and provides superior heat dissipation compared to traditional round wire.
The polyimide diaphragm is the tonal differentiator. Unlike titanium's bright, aggressive character, polyimide offers a smooth, controlled high-end with excellent internal damping. It produces a natural, fatigue-free sound that flatters a wide range of program material - from vocal-heavy content to full-range music. This makes the DE-4402 particularly appealing for applications where listener comfort matters as much as output level.
A 1.75 T flux density magnetic circuit provides strong, consistent motor force for tight diaphragm control and low-distortion performance across the entire operating range.

The DE-4402 occupies a sweet spot in the compression driver landscape: it has the thermal muscle of a flagship driver (44.4 mm coil, 60 W RMS, 1.75 T magnet) but pairs it with a polyimide diaphragm that prioritises smoothness over aggression. The result is a driver that can play loud all day without ever sounding harsh - a quality that audiences notice even if they can't name it. For system designers who want professional-grade output and listener comfort, the DE-4402 is an exceptional choice.
