The Bmw Car Stereo

M3 speakers, Z3 speakers

BMW owners know that their cars come with many special features. Leather interiors and superior handling are commonly enjoyed. Perhaps you are in possession of the new M3 Coupe, with its V-8, 414 horsepower engine and flared fenders. Drivers in love with a sports drive likely have a BMW Z3 Coupe or Roadster sitting in their garages. The control you get behind the wheel of a Z3 is what many sports car drivers relish. Many savor their morning and evening commutes much more now that they have chosen their BMWs. The ride in your BMW can be made even more pleasurable when you use quality M3 speakers or Z3 speakers in conjunction with your car's audio system. Speakers can make or break your enjoyment of your music as you drive along, so it makes sense to invest in speakers that do their job well.

The M3 speakers and Z3 speakers, like other speakers, act as the go-between to convert the digital signals stored in various formats into sounds that you can hear. Sound is created by changes in air pressure that produces a wave that, when it reaches your eardrum, vibrates it, which our brains receive as a sound. Your favorite musical artist, for example, sings his or her song into a microphone, and it is encoded as an electrical bit or byte on whatever recording media is being used. When you play these electrical signals back on your iPod, for example, the amplifier in your iPod sends the electrical signal to the speaker, which turns it into vibrations that your ears can pick up as sounds, and thus you can hear your song.

A good set of speakers is quite sensitive to changes in air pressure, which results in a better quality sound when your songs play on those speakers. Speakers consist of a diaphragm, voice coil, magnets, and some type of enclosure. The diaphragm, which is also known as a driver, is held in suspension over the voice coil, which is attached to the bottom of the diaphragm. Under the diaphragm and the voice coil is the permanent magnet. Vibrations to the diaphragm are caused when electricity flows through the voice coil. Fluctuations in the electrical current cause the vibrations to occur in the voice coil, because the electromagnet of the voice coil is both attracted to and repelled by the permanent magnet beneath it. Thus, vibrations in the diaphragm occur, based on the electrical signal from your song, which leads to the production of sound waves. Because higher-pitched sounds are produced at higher frequencies of vibration, those sounds are best produced on a driver designed to accommodate more vibration. Those are tweeters. Low sounds come across as most lifelike on drivers called woofers, while midrange drivers capture the midrange frequencies best.

It's the simple things in life that can make it most enjoyable, and excellent sound produced on your BMW's speakers is one of those that mean so much.
