What is xMax?
The company has commercialized some of these technologies to create xMax, the world’s first carrier-class cognitive radio network. xMax’s standards-based IP architecture minimizes network deployment, management and operational costs while simplifying the delivery of fixed and mobile services.
What is xMax mobile voice and data?
Fig:1.1 Logo of xG 1.3 xMax Mobile Voice and Data Overview: xMax is a mobile voice and data solution from xG Technology that has been designed to address the issues raised above and more.
What type of modulation does The xMax use?
The system uses orthogonal frequency division modulation (OFDM) which is found in other state-of-the-art wireless systems such as LTE, WiMAX, WiFi and other solutions. The xMax system utilizes proprietary long OFDM symbols, which allow longer cyclic prefixes.

What is the difference between xMax and XLIM?
Xlim is always larger than Xmax but is often not published by the supplier. Some unscrupulous suppliers actually state the value for Xmax as what should be Xlim so it is always wise to test carefully. The diagram shows what is known as an overhung design because the voice coil windings extend beyond the magnetic zone.

What is a good xMax for a subwoofer?
For entry-level 10- and 12-inch subwoofers, rated for 300 to 450 watts, an Xmax of 10 to 12 mm is good. Stepping up to mid-level woofers with power ratings between 500 and 600 watts typically results in the Xmax spec jumping up to 14 or 16 mm in each direction.
What is xMax and how is it calculated?
The simplest way to calculate the Xmax specification is to subtract the thickness of the top plate from the height of the voice coil winding and divide it by two. This calculation describes how far the woofer (or midrange or subwoofer) cone can move forward while keeping the voice coil inside the magnetic gap.
How to specify the xMax parameter of a speaker?
A second way to specify the Xmax parameter involves using acoustic test equipment and laser-based cone excursion measurement. Using this method, a signal is fed to the driver being tested at an increasing level until the speaker’s output reaches a distortion level of 10%.

What does xMax mean on a speaker?
Xmax is commonly measured as the amount of 1-way excursion while staying within 70% of the Bl value (motor strength). As the coil moves outside of the magnetic gap of the motor, the woofer looses strength, and as a result, control over the cone. You can’t simply look at xmax to determine what will be louder, there are too many other variables.

What is The xMax of the Sony es xs-w104es 10-inch subwoofer?
The Sony Mobile ES XS-W104ES 10-inch subwoofer has an Xmax of 6.5 mm and is rated for 450 watts per the CTA-2031 standard. Those who care less about sound quality and are interested only in achieving maximum sound pressure levels can continue to increase the power to a speaker beyond the Xmax value.
