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 for optimal performance and reliability.
Sensitivity (measured in dB SPL at 1W/1m) is crucial: higher sensitivity means louder output with less amplifier power. Look for at least 95 dB for professional use. Power handling (RMS and peak) should match your amplifier's output to avoid damage. Frequency response should be flat and wide enough for your application—typically 50 Hz–20 kHz for full-range speakers.
Impedance (usually 4, 8, or 16 ohms) must match your amplifier's stable load range. Lower impedance draws more current, so ensure your amp can handle it. Also consider cabinet construction (braced plywood for durability), driver quality (e.g., neodymium magnets for weight savings), and crossover design (high-quality components for clean sound).
For professional touring or installation, SSOUNDS passive speakers are engineered with high-sensitivity drivers, robust crossovers, and durable enclosures to deliver consistent, high-SPL performance. Our systems are designed to pair seamlessly with SSOUNDS amplification for predictable, reliable results.
Key things to consider
- Sensitivity: ≥95 dB for efficient use of amplifier power.
- Power handling: RMS rating should match amplifier output; allow headroom.
- Impedance: Verify compatibility with your amplifier (4, 8, or 16 ohms).
- Frequency response: Choose a range that suits your content (e.g., subwoofer for low end).
- Build quality: Look for braced plywood, quality drivers, and robust crossover components.
