Product Description
DE-7501
Specifications:
Product Overview
The DE-7501 is a heavy-duty compression driver designed for high-output sound
reinforcement where maximum SPL and extended low-mid driver integration are critical.
Built around a large 3-inch pure aluminium ribbon (ALR) voice coil and your choice of
titanium or composite diaphragm, it delivers exceptional power handling, low distortion,
and smooth off-axis response. The high-flux ferrite Y35 magnet system generates 1.80
T of magnetic density, providing outstanding efficiency and dynamic headroom. With a
remarkable 109 dB sensitivity and an 80W RMS pink-noise power rating, the DE-7501
is engineered to perform under the most demanding acoustic loads.
Key Features
• Dual throat options (1.4" / 2.0") for flexible horn matching and dispersion control
• Choice of titanium or composite diaphragm to balance brightness and warmth
• 3-inch pure aluminium ribbon voice coil for superior thermal dissipation
• 109 dB sensitivity - class-leading output with minimal amplifier power
• 80W RMS power handling (pink-noise rated) for continuous high-SPL operation
• Dual impedance (8 Ω / 16 Ω) for versatile system design
• 1.80 T flux density from high-grade ferrite Y35 magnet assembly
Typical Applications
• Large-format line array modules and touring PA systems
• High-power full-range and bi-amped loudspeaker cabinets
• Stadium, arena, and outdoor festival sound reinforcement
• Theatre, concert hall, and house-of-worship main systems
• Cinema surround and premium installed sound systems
• Rental and backline equipment requiring bulletproof reliability
Usage Notes
The DE-7501's extended low-frequency response down to 800 Hz allows it to
seamlessly cover the upper midrange in three-way system designs when paired with an
appropriate horn. For two-way configurations, a crossover frequency of 1.2 kHz or
higher (24 dB/octave slope recommended) will ensure optimal diaphragm protection
and tonal balance. The dual-throat design enables acoustic engineers to select the
optimal entrance aperture for a given horn's dispersion and loading characteristics.
In high-SPL, long-duration applications, ensure adequate cabinet ventilation around the
magnet structure to manage voice coil temperature. The bolt-on mounting system
should be periodically inspected-especially in touring or outdoor environments-to
maintain a consistent acoustic seal and prevent hardware fatigue.
