How do I choose a passive speaker?
Quick answer
Choose a passive speaker by matching its power handling, impedance, and sensitivity to your amplifier, and by evaluating its frequency response and dispersion for your venue size and application.
First, ensure your amplifier can deliver the speaker's RMS power rating at the correct impedance (typically 4 or 8 ohms). A good rule is to have an amp that provides 1.5 to 2 times the speaker's continuous power rating for headroom. Sensitivity (dB SPL at 1W/1m) indicates how efficiently the speaker converts power into volume; higher sensitivity (e.g., 98 dB+) requires less amplifier power for the same loudness.
Next, consider the speaker's frequency response and coverage pattern. For full-range sound, look for a response that extends low enough (e.g., 50-60 Hz for music) or plan to add a subwoofer. Dispersion (e.g., 90° x 60°) should match your listening area: wider for short throws, narrower for long throws to avoid reflections. SSOUNDS passive speakers are engineered with optimized waveguides for consistent coverage and high intelligibility.
Finally, evaluate build quality and application. Passive speakers are ideal for permanent installations or when you want separate control over amplification. Look for robust enclosures (plywood or polypropylene), reliable drivers, and protection circuitry. SSOUNDS offers a range of passive point-source and line array elements designed for touring and fixed install, with rigorous testing for durability and sonic performance.
Key things to consider
- Match power handling (RMS) and impedance (ohms) to your amplifier.
- Higher sensitivity (dB) means louder output with less power.
- Choose frequency response and dispersion based on venue size and content.
- Consider enclosure material and driver quality for reliability.
- SSOUNDS passive speakers deliver professional-grade performance for any application.
