Speakers & Subwoofers

Repairing speakers can be a tedious task. Without a steady hand, it is easy to permanently damage a speaker. When replacing the speaker cone or working on its voice coil, it is necessary to remove...

Audio loudspeakers produce sound by converting electrical energy into vibrations. The resulting vibrations meet air molecules, creating sound waves for each frequency in the audio spectrum. The...

Home speakers and auto speakers are more similar than you might think, but the main differences come in the the function of each and the overall look of your set-up. These differences are...

A dual-coil magnet or bifilar coil magnet, first created and patented by Tesla, is used most often as a resistor in electronic appliances, a device created to oppose electric currents. Like other...

As wonderful as the sound that comes from them, speaker coils are, by their nature of sensitivity, very brittle. They can be repaired---several times over, even---but the sound might never be the...

Speakers are analog devices similar to human ears. Woofers and tweeters produce sound when an electrical current is applied to a magnetic coil, causing the speaker's diaphragm to shift and create...

A speaker converts electrical energy into audible sound waves. These sound waves are created using a complex device made of metal, magnets, wire, plastic and paper. The vibrations are created by...

Physical vibrations, or sound waves, are interpreted through electrical signals that create the amplified sounds emitted from speakers. But the process that creates the amplification and...

Speakers may come in all different shapes, sizes and, of course, prices. However, their construction is relatively simple and similar. Though it may seem like there is a whole slew of advanced...

Given that some audio speakers can cost hundreds of thousands of dollars, you might think that the science behind speakers is equivalent to rocket science. While meticulous design and engineering...

While a subwoofer may sound like a fancy peripheral, it's actually just a large speaker, often with its own built-in power supply. The subwoofer uses a large woofer to replicate only the lowest...

The voice coil of the speaker gets its name because it is an electromagnetic coil (wire around a piece of metal) that produces sound. The voice coil is the heart of the speaker and converts...

Speakers--from tiny earphones to the colossal ones used at rock concerts--all work on the same principles, and they all work much like our ears do. Sound travels in waves through the air. We hear...

A speaker relies upon an electromagnetic coil, referred to as a voice coil, to oscillate and vibrate a cone or dome, which is attached to the coil. If the cone or dome becomes disattached,...

You've been listening to music for years, but have you ever really thought about how a speaker actually creates sound? The speaker cone is the heart of the speaker and provides essential...

To understand how a computer speaker works, you must first learn how sound works. It is a vibration that can travel through air, liquid or a gas. Contrary to science fiction, sound can not be...

Speakers have a number of moving parts, making them highly susceptible to ware and tear over extended periods of time. As the cone of your speaker dries out over time, it can develop cracks and...

Neil Young may keep on "Rockin’ in the Free World," but anyone who’s ever blown a speaker knows how much of a damper this can put on your next party or air guitar concert. Use these steps to fix a...
