So choosing is not only based on formal criteria. It is also necessary to take into account their preferences and acoustic properties. Among them:

• output power;
• format;
• number of lanes;
• subwoofer;

Number of lanes

The column can be selected depending on the number of speakers corresponding to a certain band of frequency range. They are:

• SSB - a versatile loudspeaker for all range of frequencies;
• two-way - with two speakers for high and low frequencies;
• three-way - with three speakers for medium, high and low frequencies.

subwoofer

This loudspeaker for the low frequency range and improve the quality of their reproduction. Subwoofer gives a well-defined saturated bass enhancing overall harmony of sound transmission.

The energy source should be selected based on the conditions of use.

For home provide better availability of the network adapter. for biking suitable internal batteries with less than the battery weight and higher capacity. For long journeysWhen there is no place to recharge the power supply, the battery will be the best choice.
