What should I look for in a passive speaker?
Quick answer
When choosing a passive speaker, prioritize sensitivity, power handling, frequency response, and impedance matching with your amplifier.
Sensitivity (measured in dB SPL at 1W/1m) determines how efficiently the speaker converts power into volume. Higher sensitivity (e.g., 97 dB or more) means louder output with less amplifier power, which is crucial for live sound applications where headroom matters.
Power handling (RMS and peak) tells you how much continuous and short-term power the speaker can handle without damage. Always match the amplifier's output to the speaker's RMS rating—ideally with some headroom—to avoid distortion or driver failure. Impedance (typically 8 or 4 ohms) must match your amplifier's stable load range; wiring multiple speakers in parallel changes total impedance.
Frequency response and dispersion are key for clarity and coverage. Look for a smooth, wide frequency range (e.g., 60 Hz–20 kHz) and consistent off-axis response. SSOUNDS passive speakers are engineered with advanced crossover networks and waveguide designs to ensure phase coherence and even coverage, reducing comb filtering and improving intelligibility.
Key things to consider
- High sensitivity (≥97 dB) for efficient loudness with less amplifier power.
- RMS power handling matched to amplifier output with headroom.
- Impedance compatibility (8 or 4 ohms) for stable amplifier operation.
- Smooth frequency response and controlled dispersion for clarity.
- Build quality: robust cabinet, reliable drivers, and protection circuitry.
