Demystifying Hifi Speaker Terminology: A Beginner's Guide

If you are new to the world of hifi speakers, the technical terminology can seem overwhelming. However, understanding these terms is essential in order to choose the right speakers that meet your needs. In this guide, we will explain some common hifi speaker terminology so that you are better informed when making a decision.

1. Frequency Range

The frequency range refers to the range of sound frequencies that a speaker can produce. It is usually expressed in Hertz (Hz) and indicates how low and how high a speaker can play. A wider frequency range means that the speaker is capable of reproducing a greater range of sounds, resulting in better sound quality.

2. Sensitivity

The sensitivity of a speaker refers to how efficiently it produces sound at a given power. It is measured in decibels (dB) and indicates how loud a speaker can play with a certain amount of power. A higher sensitivity means that the speaker can play louder with less power.

3. Impedance

Impedance refers to the resistance of a speaker to the current flowing through it. It is measured in Ohms (Ω) and indicates how much resistance a speaker offers to the amplifier. It is important to ensure that the impedance of the speaker matches the impedance of the amplifier to avoid damage to both.

4. Woofer, Midrange, and Tweeter

A hifi speaker typically consists of different drivers, including a woofer, midrange, and tweeter. The woofer is responsible for producing low frequencies, while the midrange reproduces the mid-tones and the tweeter produces the high frequencies. By using different drivers, a speaker can achieve a wide frequency range and create a detailed sound image.

5. Crossover

A crossover is an electronic circuit that ensures the correct frequencies are sent to the appropriate drivers. It divides the audio signal into different frequency bands and sends them to the corresponding drivers. A well-designed crossover ensures a seamless transition between the drivers and prevents distortion in the sound.

6. Bi-wiring and Bi-amping

Bi-wiring and bi-amping are techniques in which the speaker cables are split and individually connected to the drivers of a speaker. Bi-wiring divides the audio signal between the woofer and the midrange/tweeter, while bi-amping separately amplifies the audio signal for each driver. These techniques can improve sound quality by reducing interference between the drivers.


As a beginner in the world of hifi speakers, understanding the technical terminology can seem overwhelming. By learning the basics, such as frequency range, sensitivity, impedance, and the different drivers, you can make better-informed decisions when choosing the right speakers for your needs. Remember to always listen to the speakers before purchasing them, so that you can assess if they produce the sound you are looking for.
