How do I choose a passive speaker?

Quick answer

Choose a passive speaker by matching its power handling and impedance to your amplifier, and by evaluating its sensitivity, frequency response, and coverage pattern for your venue.

Selecting a passive speaker starts with matching it to an external amplifier. Check the speaker's power handling (RMS and peak) and impedance (typically 4, 8, or 16 ohms) to ensure your amp can deliver sufficient clean power without overloading. A good rule is to choose an amp that provides 1.5 to 2 times the speaker's RMS rating for headroom.

Next, consider sensitivity (dB SPL at 1W/1m) – higher sensitivity means louder output with less power. Frequency response tells you the bass extension and overall tonal balance; for full-range use, look for a response down to at least 50–60 Hz. Coverage angle (e.g., 90° x 60°) should match your listening area to avoid dead spots or excessive reflections.

Finally, assess build quality and application. Passive speakers are ideal for permanent installations or when you want to choose your own amplification. SSOUNDS passive series offers robust construction, high sensitivity, and consistent coverage for professional sound reinforcement. Always audition speakers in your space if possible.

Key things to consider

  • Match power handling (RMS) and impedance to your amplifier; amp should deliver 1.5–2x RMS for headroom.
  • Higher sensitivity (e.g., 95 dB+) means louder output per watt – crucial for efficient systems.
  • Check frequency response for your needs; subwoofers may be needed for deep bass.
  • Coverage angle must suit your venue shape and size to ensure even sound distribution.
  • Consider durability, warranty, and manufacturer support – SSOUNDS passive speakers are built for reliability.
