About this product
Engineered as an original equipment equivalent part, this speaker offers a reliable, low-cost solution for repairing existing products rather than replacing whole systems. The steel frame and standard 4" form factor ensure mechanical compatibility with thousands of legacy and current devices.
Features
• Maximum Output Power: 45W• Impedance: 4 ohms
This speaker delivers functional reliability at a competitive price point. With 45W peak power handling and a 4-ohm impedance, it pulls higher current from low-voltage amplifiers (common in automotive and portable devices) to achieve noticeable volume.
• Sensitivity: 88 dB/w/m • Frequency Range: 92-15KHz
The 88 dB sensitivity ensures acceptable efficiency for moderate-powered amps (5–20W RMS). The steel frame provides durability in vibration-prone environments (e.g., car doors or portable equipment)
• Magnet Dimension/Weight: 5.4 oz • Voice Coil: 0.76"
Aluminum-clad copper wire offers better heat dissipation than plain copper, improving long-term reliability in thermally constrained enclosures.
