Some Key Specs to Consider

There are a few key factors to keep in mind when shopping for boat speakers. You’ll want to consider key specs such as sensitivity, power handling, frequency range, impedance…etc. All of these factors can be helpful in making your decision. However, if you’re interested in buying the loudest marine speakers, speakers’ sensitivity and power handling should be the main two specs to pay close attention to.

That’s not to say that the other key specs aren’t of much importance. Quite honestly, they do matter. But in this case, the most critical key specs to look out for are sensitivity and RMS power handling.

  • Sensitivity — measures the amount of sound a speaker yields from the power applied to it. It goes hand in hand with power handling. A pair of speakers with high sensitivity rating require less power to produce the same amount of sound as a pair of speakers with a lower sensitivity rating.
  • Power handling — It is A measure of how much power (watts), a speaker can take before it is damaged.
    • Peak Power Handling: It refers to the maximum amount of power a speaker can handle during a brief musical burst.
    • RMS Power-Handling: It refers to the maximum amount of power a speaker can handle on a continuous basis.
