Power-Rating on Subwoofers: How to Choose the Best?

One of the confusing parts of buying a subwoofer is its power ratings. How much power do you need for your subwoofer? To find out, continue reading this.

If you are planning to purchase a subwoofer, whether your goal is to enhance the low-frequency audio production or to build a home theater system with ground-pounding bass, you need to know which subwoofer can support power and peak performances; this is where power ratings come in.

What is a power rating on the subwoofer?

One of the essential factors to consider when buying a subwoofer for a home theater system is its power ratings. Power rating is a measurement of how much energy a subwoofer need to support a specific audio peak over a specific period.

There are two power ratings that you need to understand – the RMS power and the Peak power.

RMS watts

RMS wattage power rating is a measurement of the continuous power handling of a subwoofer or a speaker. RMS’s values are often lower than the peak ratings, but it is an essential specification when choosing the right subwoofer. It is the average power that the subwoofer or speaker can handle every day or every time you turn on your surround sound system without compromising the quality of sound or suffering from damage.

How to choose?

If you have a sub with 800 RMS watts, you need to pair it up with an amplifier or a receiver that can produce 800 RMS watts too.

Peak power rating

Peak power rating is a measurement of how much power can the subwoofer handle during short and loud bursts of sound for a limited period without resulting o distortion. Take note, the peak power level is a measurement of the highest sound but can only be maintained at a fraction of a second. If the subwoofer is often at its peak, it may damage the wire, including damaging the voice coils.

How to choose?

If you are planning to purchase a subwoofer that can handle loud and deep bass, you need to choose a subwoofer with the right power rating.

Tips on how to choose the right subwoofer according to power handling:

  • Determine how loud do you want your audio when watching a movie or listening to music. If you want to experience great audio production, you may want to choose a 1000-watt powered subwoofer. Check this ELAC Debut 2.0 SUB3030 review to find out.
  • Closely check the RMS and the peak ratings.
  • Check compatibility with your amplifier or receiver.
  • Try reading reliable posts and reviews for additional details on power handling on subwoofers and speakers.

Final Thoughts

Understanding the power ratings on the subwoofer and other speakers will help you choose the right surround sound system for your home theater. And when matching the subwoofers to the amplifiers, you should not forget to compare the RMS value and the peak ratings of the two units to avoid sound distortion or permanent damage to the surround sound system.
