XFire BMW 3 Way Audio Upgrade
Understanding the Basics of Speaker Drivers
To avoid any confusion let’s go over a couple of basic points regarding car audio speakers. These basics are also applicable to regular speakers. You will hear a lot about speaker drivers in the next few paragraphs. When you open a speaker box or enclosure, you will see one or two different cone-shaped round parts (or even ribbons or domes, in some cases). These are the drivers. They vibrate when sound is produced.
Sounds have various ranges of frequencies, from low to high. Different sized drivers are equipped to handle different ranges of frequencies. The human ear can handle frequencies between 20Hz and 20,000Hz. There is no one driver capable of handling that full range. So speakers usually have more than one driver, to better produce different ranges of sound.
The three main types of drivers are woofers for low frequency or bass (below 200Hz), tweeters for high frequency or treble (above 2,000Hz), and a mid-range driver for everything in between (200Hz – 2000Hz). And the system uses a device called a “crossover” to split the original sound signal into two or three different signals of different frequencies to feed the various drivers.
2-Way vs. 3-Way Speaker Upgrades
This is just a simple, general method of distinguishing between different car speaker systems, based on the number of drivers they have. When a speaker system has more than one driver, the input sound signals have to be split into the different frequencies that they specialize in. The low-frequency sound signals are sent the way of the woofer, and the high frequencies are pushed to the tweeter.
So a two-way speaker has the sound signals split two ways, while in a three-way speaker they are divided in three ways. This is a very simple and easy way of classifying different kinds of speaker designs. You can have a single speaker box with two or three drivers (a coaxial/full range design), or a speaker system made up of multiple drivers in individual boxes (components system design).
A 2-way component car audio system will have a set of woofers and set of tweeters, in separate boxes. You can have multiple pairs or tweeters and woofers, but the system remains a 2-way system.
The addition of external crossovers adds to the overall quality of component systems, and 3-way systems really benefit more than 2-way in this format. The mid-range becomes more accurate, and the ability to better position individual tweeters and woofers really create a different sonic experience.
When done right, and using high-quality components, a 3-way system is generally better than a 2-way speaker system regarding overall audio quality and fidelity in component systems.

BMW XFIRE Audio Upgrades
XFire BMW 42S Speaker Upgrades are specially developed for BMW and are 100% custom. BMW standard audio system vary from ‘Base’ delivered without tweeters and woofers are small Or ‘Hifi’ with tweeters but with small woofers. The result is dull noise and reduced dynamics. The lack of clarity and volume is to most the disappointment you would expect with a premium car brand.
XFire BMW 42S Speaker Upgrade is made as a factory replacement, but without any compromises. Only the finest materials are chosen to ensure a true enhancement of your audio experience. Whereas the standard system will use common materials in midranges such as ferrite motors, XFire opted for neodymium.
Neodymium is a lightweight design, yet costly, but more powerful than standard magnets. One of the benefits, besides less weight, is also the increased performance in both audio reproduction and sensitivity. In addition we increased the thermal capacity of the speaker by using a vented pole, this will minimize both distortion and impedance rise, that way you are sure you won’t have as much loss of power sent from your factory amplifier system.
