Driver Classification
Driver type: Compression driver
Intended system topology: 2-way PA loudspeaker
Design focus: Cost-controlled, reliable, mid-tier SPL applications

Electro-Acoustic Parameters (Driver-Intrinsic)

Impedance & Resonance Characteristics
(measured without horn loading)

Primary diaphragm / rear-chamber resonance: approx. 1200 Hz
DC resistance (Re): approx. 5.5 Ω
Note: Resonance data is provided as an indicator of the mechanical stress region and is not intended as a usable crossover frequency.

Sensitivity (Horn-Loaded, System-Dependent)
Typical sensitivity with appropriate 1” PA horn: approx. 110 dB (1 W / 1 m)
Actual sensitivity depends on horn geometry and measurement conditions.

Recommended System Integration
Typical system type: 2-way PA loudspeaker
Recommended crossover frequency: ≥ 1.5 – 2.0 kHz (system dependent)
Recommended filter slopes: ≥ 12 dB/oct (24 dB/oct preferred)
Compatible horn types: 1” throat PA horns (constant-directivity or exponential)

Design Intent
The 140FCD is designed for compact PA systems requiring predictable performance, mechanical reliability, and production consistency. The design prioritizes stability and repeatability over maximum SPL, making it suitable for high-volume professional audio products where uniform voicing and long-term availability are essential.

Application Guidance

Recommended for:
● Budget-sensitive PA products
● Compact 2-way loudspeakers using 8”–15” LF drivers
● Portable and installed PA systems
● OEM and DIY designs prioritizing consistency and reliability

Not intended for:
● Large-format, high-SPL touring systems
● Very low crossover frequency applications (below approx. 1.2 kHz)
