How The M3 And Z3 Speakers Are Engineered To Work With 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 V8 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 gobetween 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 higherpitched 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.

History Of The Mercedes
We associate the name of Mercedes with wealth or car quality. What many of us dont know is that the car itself dates back to over a hundred years.
To tell the story of Mercedes brand cars you first must know the characters involved with the company. Those characters are Gottlieb Daimler and Carl Benz. Both men were born only 60 miles apart in southern Germany. Daimler was born March 17 1834. A decade later on November 25 Carl Benz was born. Although they grew up with little in common machines from an early age fascinated both boys. Because their approach to building cars was quite different it is doubtful though that they met or even knew what the other was doing.
In 1886 Carl Benz built a motorized tricycle. His first fourwheeler the Victoria was built in 1893. The first production car was the 1894 Benz Velo which participated in the first recorded car race the ParisRouen race. In 1895 Benz built his first truck.
In 1886 Gottlieb Daimler literally built a horseless carriage. Although we think of the car as being German its history dates far back into America as well. In 1888 Daimler made a business deal with William Steinway of piano fame to produce Daimler’s products in the US. From 1904 until a fire in 1907 Steinway produced Mercedes passenger cars Daimler’s light trucks and his engines on Long Island.
Ironically history says Daimler generally considered to be the father of modern automobiles never liked to drive. On March 6 1990 Daimler died leaving control of his company to his chief engineer Wilhelm Mayback. By November 22 of that year DaimlerMotorenGesellschat had produced a special car for Emil Jellinek. Jellinek named the car after his tenyearold daughter Mercedes. This car was lighter and smaller than the standard car of its day and because of this was able to reach a top speed of 55 miles per hour.
Up until 1908 Daimler had overshadowed Benz in racing endeavors. At the 1908 French Grand Prix Benz took second and third place behind Lautenschlager driving a Mercedes.
At the beginning of the First World War both factories were converted into production sites for war materials although both resumed producing cars after the war. Social unrest and a falling economy characterized postwar Germany. Little or no fuel for cars and a 15 luxury tax made automobile production increasingly disastrous.
The German economy continued to worse and a new Benz automobile eventually cost 25 million marks. Although nearly 15 million cars were registered in the world in 1923 over 80 of them were registered in the US and over 1/2 were Fords. The Mercedes was too expensive.
In 1924 from sheer economic necessity Benz and DMG signed an “Agreement of Mutual Interest.” Although both companies retained their identities the agreement was valid until the year 2000. The two companies merged with relative ease on June 28 1926.
A new insignia was needed to represent the merger. The design was a threepointed star wreathed with laurel. The word “Mercedes” was at the top and the word “Benz” was at the bottom. The merger did the new company well. Production of MercedesBenz rose to 7918 MercedesBenz automobiles in 1927. The MercedesBenz diesel truck was put into production in 1927 also.
The first two automobiles to sport the MercedesBenz name were the Stuttgart and the Mannheim. Then in 1928 the Mercedes SS was introduced by MercedesBenz. This graceful body was made possible by a hood line that barely cleared the engine.
MercedesBenz launched their biggest and most prestigious car to date in 1930. The 770 Grosser was powered by an 8 cylinder 7.6 liter engine. A car for the truly wealthy of the world it was quite an automobile for showing off in a world economy still reeling from the Wall Street Crash of 1929.
The cars of the 1930s produced great racing success for MercedesBenz. The silver metal bodywork gave rise to the name Silver Arrows when the W25 racer of Rudolph Caracciola fame had the white paint removed to lower its weight.
W125 200 mph top speed won seven out of thirteen races in 1937 followed by the successful W154. In 1939 MercedesBenz built a small V8 races specifically to win the Tripoli GP. It did win!
The MercedesBenz 170V gave Mercedes the capability of surviving and then recovering from WW II.
Today the Mercedes of course is still being built and is still revered as a car of quality.
