FAQs – Speakers

• Power Rated (RMS or nominal power): The continuous power the speaker can handle without damage.
• Power – Max (peak power): The highest short-term power the speaker can handle. Exceeding it can cause distortion or damage.

Speakers with lower impedance (4 Ω) draw more current, potentially delivering higher volume if the amplifier can support it. Higher impedance (8 Ω) reduces current draw, making it easier on the amp but sometimes delivering lower maximum volume.

Sensitivity indicates how loud a speaker is at a given input power. Higher dB ratings mean more sound output for the same power, translating to a louder speaker at the same wattage.

Manufacturers may provide multiple reference points to illustrate performance in various real-world scenarios. Sensitivity measured at different power levels or distances helps designers and users understand how the speaker behaves in diverse setups.

• 800mW speakers suit small devices or short-range applications (e.g., handheld gadgets).
• 8W speakers can handle higher power, suitable for slightly larger enclosures or scenarios requiring more volume, such as portable audio systems.

Vehicle speakers are designed for the automotive environment, featuring robust cones, higher power handling, and durable materials to withstand temperature extremes, vibrations, and moisture. They often have larger diameters and deeper enclosures for better bass response.

Car audio amplifiers are typically optimized for 4 Ω speakers, balancing power output and heat dissipation. Using 8 Ω or other impedances can affect volume levels and amplifier efficiency, requiring system recalibration.

Higher sensitivity means the speaker can reach louder volumes with less power—critical in a car environment where road noise competes with audio. Even a few dB differences can significantly impact perceived loudness.

Vehicle speakers are frequently exposed to dynamic peaks (e.g., bass-heavy music or sudden volume changes). A higher “Power – Max” ensures they can handle short bursts of extra power without damage, while the “Power Rated” (RMS) figure indicates safe continuous power handling.
