Glossary of Terms - Speaker Terminology

There are many terms used to describe features, functions, capabilities, and types of speakers. 

Dual Cone
A dual cone speaker is classed as a full range speaker, but instead of a separate tweeter it has a small cone directly connected to the voice coil that reproduces the high range frequencies. While less expensive than a separate tweeter, it is not as efficient.

Mid-range Speaker
A mid-range speaker is usually between 3.5” and 6.75” and reproduces mid-range frequencies. They are normally used in a system that has separate speakers for low, mid, and high range frequencies.

Tweeter
Tweeters reproduce high-range frequencies. In two and three way speakers the tweeter is mounted in the center of the cone on a pole piece, and are a separate unit on component speakers. Tweeters are ideally placed equidistant to the listener's ears.

Component Speakers
Component speaker systems are made up of more speakers (or "components") due to each part being highly specialized to reproduce one type of sound. This allows for much more customizable imaging which in turn allows much higher quality sound stage potential.

Sound Stage
Refers to the placement of speakers in relation to the "depth" of sound heard.

Imaging
The ability a stereo system has to reproduce the location of individual instruments. The greater the imaging ability, the greater potential of the sound stage.

Speaker Surround
The material attaching the speaker cone to the frame, most commonly butyl rubber. Some manufacturers use foam or cloth. The surround allows the cone to travel in and out without restricting the length of travel.

RMS
The ideal amount of power, usually expressed in watts, a speaker is designed to receive for best sound quality.

Maximum / Peak Power
The maximum amount of power, usually expressed in watts, that can be sent to a speaker without immediate risk of damage to components.
