Soundstream X05-Pro Processors Spectrum Review

The technique of high-efficiency full-range.

The race to the increase in sound pressure reproducibly led to what today we call full-range systems. Unlike plants that reproduce high-SPL sound pressure only a small range of low frequencies and more behind closed doors, the full-range systems accurately cover the entire audio range (or at least the 100 Hz and up).

A car with a full-range system is so enjoyable every day, several people at once and can literally transform an evening open: opening doors and trunk and inserting the latest dance hits is easy to involve all those present, like disco summer, thanks to high-volume sound reproduction complete and intelligible.

Unfortunately, enthusiasm and excitement, do not go hand in hand with performance and reliability of components, which is why it is good that a full-range system is designed, built and used with knowledge of the facts, just as with an implant or SQ SPL.

By following the instructions in the manual 'PRO' Unicars made by Italy, will be able to exploit the huge potential of Soundstream PRO Series drivers and enjoy the exceptional performance of your system with high efficiency.

To compose an ad hoc system, so you should choose the door configurations that you find in the manual 'PRO' and combine it with a subwoofer section as efficient as possible.

Given the special characteristics of these speakers is absolutely necessary to follow the filter cutoff frequencies shown in the bottom of this page. Would not obey them work outside the confines of the project, with exaggerated levels of excursion, resulting in distorted sound and a premature rupture of the same.

To help in this task, there is the electronic x-over-PRO Series PRO STXO5 the possibility that these speakers are ideal for special operations. With the 5-way and wide range of cutoff frequencies selectable, even allows the creation of full-range systems are particularly complex.

Make responsible use of your full-range system Soundstream!

Crossover Knowledge

The crossover is a device which allows the subdivision of the range-range multiple audio (commonly called "streets"), each of which will power the corresponding speaker. To operate the attenuation of frequencies "unwanted" property is exploited reactive electrical components, especially inductors and capacitors. 

In particular, the inductance shows a low resistance (typically one of the wire that is) from 20 Hz to the frequency of intervention, beyond this value will increase the resistance with a progression of 6 dB per octave (remember that is the eighth ' interval between any frequency and its double) up to 20000 Hz capacitor behaves exactly the opposite, its resistance will decrease with increasing frequency with a progression of - 6 dB per octave Let's apply this concept in practice . Suppose we want create a system consisting of a woofer and a tweeter, so we split the audio range into two parts (two-way system) and identify, based on the characteristics of the speakers and the objective of the project, which will be the frequency separation between the two zones (crossover frequency), for our example a frequency of 3000 Hz  then adding a series inductance to the woofer to reduce frequencies above 3000 Hz (low pass) and a capacitor in series with the tweeter to mitigate the frequencies below 3000 Hz (high pass).
