Optimal impedance of 4 ohms for the Rebec SA70 midrange driver

With an impedance of 4 ohms, the Rebec SA70 midrange speaker offers a perfect compromise between performance and compatibility. This impedance ensures compatibility with most commercially available car audio amplifiers, as 4 ohms is a common impedance for mobile audio applications. A lower value could increase efficiency, but also make the system warmer and less efficient, while a higher impedance might demand more power from the amplifiers. Thus, the SA70 hits the spot for optimal efficiency and load.

Reliable rated power of 25 W (RMS) for consistent sound

The Rebec SA70 boasts a rated power of 25 W (RMS), ensuring stable operation and balanced sound under normal listening conditions. This power ensures consistent sound output without distortion. A higher power output could result in louder output and potentially more distortion, which is risky for long-term use. A lower power output would limit the maximum volume, but efficiency could be slightly improved. In its current specification, the SA70 offers a solid balance between power and acoustic fidelity.

Maximum power of 50 W: Flexibility for dynamic peaks

For dynamic music or particularly loud passages, the Rebec SA70 boasts a maximum power output of 50 W. This peak power is essential for moments when the midrange driver briefly requires more power. Such peaks are important for reproducing the full dynamic range of an audio signal.
