Most homes today have some kind of entertainment centre in their living room. It is possible to enjoy the latest blockbuster from the comfort of your sofa while taking advantage of the latest technology, and those special effects seem to get better with each new movie. Yet while you may have a big-screen TV to make the most of those visual effects, you may be receiving the sound through built-in speakers. If you really want to enjoy this form of entertainment properly, then you need to get some quality, standalone units instead. But what is the difference between the speaker you currently have and this other kind of speaker, and how can take full advantage of this change?
How Speakers Work
It pays to understand exactly what sound is. When engineers, singers or musicians record music in the studio, it is converted into the digital representation of a sound wave. When the music is played back through your equipment, the digital data is converted back into electrical signals and sent to the speaker. When it arrives, the speaker will vibrate at a certain frequency, and this will send out sound waves that recreate the original sound.
Within each speaker is a driver. This is made up of a magnet attached to a frame on one side and a diaphragm device on the other. This has a membrane, which is a very thin layer of material, directly attached to the magnet on one end and to a circular frame on the other.
Within the magnet is a copper coil. As a signal is sent to the driver, the coil will begin to vibrate, and this will cause the membrane to fluctuate. As it does so, it will push air out in front of it, and this movement is the sound wave. As soon as these waves reach the ears of the listener, the brain will interpret them as the appropriate sound.
High-quality speakers have multiple drivers to produce the full spectrum of frequencies effectively. They will have a subwoofer for bass sounds, a tweeter for high-frequency sounds and a couple of other drivers in between. These will all be managed through a crossover device.
When you place your speakers, you need to take into account the length of each sound wave. You don't need to worry too much about the subwoofer as the sound waves produced by it are probably bigger than your room, so you can place it anywhere within reason. However, you will need to place your main speakers so that they are level with your ears and directly in front of you, due to the fact that the sound waves here are only a couple of centimetres long.
Buy the Best
It pays to buy the best speakers you can find, as they will replicate the sound more authentically. Ask your supplier for further advice to help you with placement.
