Buying Guide: Class D Audio Amplifiers

1What power output should I look for in a Class D audio amplifier?

Look for at least 50-100 watts per channel for home use, with 150+ watts for larger rooms or car audio. Class D amplifiers are efficient, so higher wattage doesn’t always mean more heat, but it does mean better dynamic range and volume headroom.

2How does Class D compare to Class AB amplifiers in terms of sound quality?

Class D amplifiers are more efficient and compact, but Class AB often provides warmer, more detailed sound. For audiophiles, Class AB may be preferable, but Class D is ideal for portability and power without sacrificing too much sonic quality when built well.

3What should I check for in terms of frequency response and distortion?

Aim for a frequency response of 20Hz–20kHz for full-range audio, and look for total harmonic distortion (THD) under 0.1% at 1kHz. Lower distortion ensures cleaner, more accurate sound reproduction, especially at higher volumes.

4Are there specific features that make a Class D amplifier worth paying more for?

Look for built-in DSP, crossover controls, and support for high-impedance speakers. These features allow for better sound customization and compatibility, making the amplifier more versatile for different speaker setups and music genres.

5What size and type of speakers work best with Class D amplifiers?

Class D amplifiers pair well with active speakers, subwoofers, or passive speakers with impedance between 4–8 ohms. They’re especially effective with modern, high-efficiency speakers that don’t require as much power to reach loud volumes.
