BMW Z3 COUPE


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.

Speakers in your vehicle, or anywhere else, are 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 from M3 speakers and Z3 speakers is one of those that mean so much.

BMW Z3


Your BMW z3 is such a delight to drive. There is nothing like heading out on the open road in this wonderful vehicle, except taking a spin in your z3 while listening to your favorite music or books on tape. There are many online sources for BMW audio upgrades. Most carry a full line of customized BMW z3 speakers as well as BMW car stereo accessories and kits for ipod, bluetooth and satellite radio integration fitting into your car's existing radio and navigation interfaces. Your BMW z3 audio system can be much improved quickly and easily.

Your BMW z3 speakers will make or break the quality of sound that you can achieve in your z3. Popular aftermarket audio components include speakers for BMW z3 audio systems available in speaker packages, subwoofer systems and speaker pairs.

Customized speakers for BMW z3 audio systems are designed to fit in your z3 with no modifications to the interior of the vehicle at all. These speaker packages come as plug and play units, making it easy even for non-mechanics to change out the speakers. By simply upgrading your speakers alone you will notice a marked improvement in the sound quality of your BMW car stereo.

BMW subwoofer systems are the perfect choice for when you want your BMW z3 audio to have maximum bass capabilities. Typically, subwoofer systems take up a great deal of room in your trunk; however, many companies offers subwoofer systems that conserve your cargo space.

Speaker pairs make a great choice when you want maximum control over every aspect of sound quality produced by your BMW audio system. Select from tweeters, midranges and midbases designed to fit your BMW z3. Tweeters are used to amplify and improve the high-pitched sounds in your music. You can replace the tweeters that came from the factory in your z3 by simply plugging in the new ones. Look for customized midrange speakers for both the z3 roadster and coupe. Without properly functioning midrange speakers, you will have distorted vocals, guitars and other sounds in your music. Only basic tools are needed to switch out these types of speakers. New midbases are easy to replace by simply keeping the factory grilles that come standard in your z3 in place. This keeps your interior looking just as it did when you bought it. Durable materials are used in the construction of our midbase speakers, so that they will last for several years.

Your BMW z3 audio system can benefit from upgrades including ipod integration and speaker upgrades. Most audio solution providers carry auxiliary input and installation accessories to make your BMW z3 audio system upgrade a breeze.

BMW Z4 GTR



Unveiling in Geneva: On the occasion of the Automobilsalon, Prof Dr Burkhard Göschel, BMW Group Board Member Purchasing and Development, introduced a new racing car for customer motor racing. The Motorsport Version of the BMW Z4 M Coupé, which has already made a big impression as a production model, is the first two-seater BMW Motorsport offers for customer teams. When it came to the development, BMW faced a huge challenge: The car had to have what is needed to race successfully on the world’s most demanding and spectacular racetrack, the Nürburgring’s famous Nordschleife. The new motorsport coupé can be used by private BMW customer teams in the German Endurance Championship and in the Nürburgring 24-Hour Race. 
The power unit of the beefy coupe is a BMW Motorsport designed 3.2-litre in-line 6-cylinder engine delivering about 400bhp, with the suspension area in particular benefiting from the knowledge gained from the successful BMW M3 GTR project.

With its varied component ranges, BMW Motorsport and BMW Racing Parts Distribution offer customer teams a new technology platform for use in many miscellaneous international racing and club sport series, with the Nordschleife enthusiasts not being the only interested party, as the brawny coupe also represents the perfect car for use in the Belgian Belcar series and other, non-European, endurance series.

The kit can be ordered from May 2006 at BMW Motorsport and will be available for an estimated 
€ 250,000 (plus VAT).
