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.
First, ensure your amplifier delivers the right power: the speaker's RMS power rating should be within the amp's output range (ideally 1.5–2x the speaker's RMS for headroom), and the impedance must match (e.g., 8Ω speaker with an 8Ω-rated amp). Sensitivity (e.g., 98 dB 1W/1m) determines how loud the speaker gets per watt—higher sensitivity means more output with less power.
Next, consider the speaker's frequency response and coverage. For full-range sound, look for a response that covers at least 65 Hz–20 kHz, and a coverage angle (e.g., 90° x 60°) that suits your listening area. SSOUNDS passive speakers are engineered with advanced DSP-tuned crossovers and high-sensitivity drivers to deliver consistent coverage and high SPL even in challenging acoustic environments.
Finally, think about build quality and application. For portable use, choose a rugged cabinet with flypoints and a durable finish; for installed systems, consider weather resistance and mounting options. SSOUNDS passive line arrays and point-source speakers are designed for both touring and fixed installations, offering reliability and support across global markets including Africa and Europe.
Key things to consider
- Match amplifier power (RMS) to speaker's RMS rating, with 1.5–2x headroom for peaks.
- Ensure impedance compatibility (e.g., 8Ω speaker with 8Ω amp) to avoid damage.
- Higher sensitivity (≥95 dB) means louder output per watt—ideal for larger venues.
- Check frequency response and coverage angle to match your room acoustics.
- Choose robust construction (plywood, metal grille) for durability in portable or installed use.
