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.
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)
Aluminum-clad copper wire offers better heat dissipation than plain copper, improving long-term reliability in thermally constrained enclosures.
