How do I choose a passive speaker?
Quick answer
Choose a passive speaker by matching its power handling (watts RMS) and impedance (ohms) to your amplifier, and by evaluating its sensitivity (dB SPL), frequency response, and coverage pattern for your venue size and application.
Start with your amplifier: ensure the speaker's RMS power rating and nominal impedance (typically 8 or 4 ohms) are compatible. The amp should deliver 1.5–2 times the speaker's RMS rating for headroom without clipping. Sensitivity (e.g., 95 dB @ 1W/1m) determines how loud the speaker gets per watt; higher sensitivity means more output with less power.
Consider the speaker's frequency response and dispersion. For speech clarity, look for a wide, flat response and controlled directivity (e.g., 90° x 60°). For music, check low-frequency extension. SSOUNDS passive speakers are engineered with optimized crossovers and high-sensitivity drivers to deliver consistent coverage and high SPL even with moderate amplifier power.
Finally, match the speaker to your venue: small rooms need 8–10" woofers; medium venues, 12–15"; large spaces, multiple cabinets or subwoofers. Factor in durability, rigging options, and warranty. SSOUNDS offers a range of passive enclosures designed for reliable touring and installation, backed by expert support.
Key things to consider
- Match speaker RMS power and impedance to your amplifier (amp should deliver 1.5–2x RMS).
- Higher sensitivity (dB) means louder output per watt; aim for 95 dB or more for efficiency.
- Choose frequency response and coverage pattern based on content (speech vs. music) and venue size.
- Consider build quality, rigging hardware, and manufacturer support for long-term reliability.
- Test with your source material if possible; SSOUNDS provides detailed specs and application guidance.
