How to Choose the Subwoofer Amps?

best subwoofer amp

Perhaps all the technical terms used to describe amplifiers can be confusing. However, we are here to make your life easier and guide you to the best subwoofer AMP.

What Does MOSFET Power Supply Mean?

MOSFET stands for Metal Oxide Semiconductor Field-Effect Transistor powered by a Mosfet power supply. Coping well with the wavering between non-conduction and full-conduction, it delivers impressive efficiency and output power.

What Does RMS Mean?

RMS is an abbreviation for route mean square. It is a mathematical calculation of the mean of a set of square numbers. This average is obtained by dividing the sum of numbers by the total number of terms. Seems confusing?

In other words, RMS means the highest level of output power that AMP can generate in a single split-second, for the loudest part of the audio. However, be aware that it doesn’t describe the maximum constant output power. As a rule, it is lower.

Amplifier Classes

Looking through the amplifiers offered by manufacturers, you may have noticed that they are marked with one or 2 letters. Remember that this categorization has nothing to do with alphabetical ordering or determining the worst and the best options.

These letters are not a grading system. They describe the efficiency of wave functions.

If you use an A-class amplifier, it should get a high-level current flowing continually. This type is a great option for those, who value sound quality above all else. The disadvantage of this class of amplifiers is that they need to conduct at all-times.

A B-class amplifier features similar single-ended push/pull functionality. The difference is that only half of the device is active at any given time. It covers one 180° portion of the 360° wave.

The D-class amplifier is considered by many experts to be the best subwoofer AMP on the market these days. Their design makes it easy to switch the devices connected between an on and off state. As a result, power is used as efficiently as possible during the idle.

Manufacturers also release G and H class amplifiers, but they are not suitable for subwoofers, so we will not consider them.
