What should I look for in a passive speaker?
Quick answer
When choosing a passive speaker, prioritize sensitivity (efficiency), power handling, frequency response, and impedance matching with your amplifier for optimal performance and reliability.
Sensitivity, measured in dB SPL at 1W/1m, determines how loud a speaker gets with a given amplifier power. Higher sensitivity (e.g., 98 dB or above) means less amplifier power needed for high output, which is crucial for large venues or battery-powered setups. SSOUNDS passive speakers are engineered with high-sensitivity drivers to maximize efficiency and reduce amplifier costs.
Power handling (RMS and peak) tells you the continuous and maximum power the speaker can handle without damage. Always match this with an amplifier that delivers clean power within the speaker's range. Impedance (typically 8 or 4 ohms) affects how many speakers you can run per amplifier channel; lower impedance draws more current. SSOUNDS designs passive speakers with consistent impedance curves for stable amplifier loading.
Frequency response and dispersion are key for sound quality and coverage. Look for a wide, flat frequency response (e.g., 60 Hz – 20 kHz ±3 dB) and controlled dispersion (e.g., 90° x 60°) to ensure even coverage and avoid feedback. Build quality, including cabinet construction and driver protection, ensures longevity in touring or fixed installations.
Key things to consider
- High sensitivity (≥98 dB) for efficient use of amplifier power.
- Power handling matches your amplifier's output (RMS and peak).
- Impedance (4 or 8 ohms) compatible with your amplifier and wiring scheme.
- Wide, flat frequency response with controlled dispersion for even coverage.
- Robust cabinet and driver construction for durability.
