The basic idea of the SACC Thechnology is very simple!
The cabinet of the loudspeaker must be neutral and deaf as much as possible, therefore incapable to add information to the original musical signal. Moreover, it was necessary to create a loudspeaker with an innovative shape and design. To do so, it was been essential to give up the traditional constructive technique, inventing a new, different one.
So it’s born SACC (Simulated Anechoic Cabinet Construction) Technology. With the use of SACC Technology for the realization of a loudspeaker we have two important results. The first one is concerning the cabinet design that for the first time it’s not dependent to a constructive technique, but on the contrary only to the imagination of the designer. The second one concerns the loudspeaker audio quality. From the outside of the cabinet it’s easy to appreciate the design of a loudspeaker but, to understand the constructive technique of it and how it works on the musical message, it’s necessary to look to its inside.

Fig. 1 - Constructive Structure of EVENTUS Audio Loudspeaker
The Fig.1 shows the structure of a loudspeaker EVENTUS Audio. You can easily notice the difference with a conventional one since a loudspeaker with SACC is realized through the overlap of elements with a particular shape, Fig.2, that joined together form the cabinet with the relative load volume for the low frequencies driver.

The inside wall have numerous prominences of different length. The inside of the loudspeaker can be compared to an anechoic room in miniature. The aim is to eliminate the onset of stationary waves thanks to the absence of parallel walls. The presences of the inside wedges allows to reduce drastically the spurious reflections in medium high frequencies. This results in an amazing audio quality of the EVENTUS Audio loudspeakers.

The graphs are referred to the measures of a conventional loudspeaker, Fig.3, and to a loudspeaker realized by SACC Technology, Fig.4. From the graphs we notice how SACC operates toward the proof signal. In the specific case, it’s a sinusoidal signal of 1.250 Hz. The proof conditions are the same for both cases: same power level of amplifier, same load volume for the driver and same low frequencies driver, a 13 centimeters put in a traditional cabinet in the first case and in a SACC cabinet in the second case. In the measure concerning the traditional cabinet we notice the presence of the harmonics which are superior than the fundamental one reproduced with almost comparable levels to it.
In the case of the SACC cabinet, some of them are completely disappeared by the graph. Others are attenuated up to 15 dB in comparison to the preceding case. This give a better acoustic combining between the mid-woofer and the tweeter. In fact, the result of SACC Technology towards the acoustic curve response of the mid-woofer allows to increase the performance of the crossover notably. Subsequently this confirm the thesis that the loudspeaker cabinet to the peer of the other components, drivers and crossover, covers a fundamental role, that as a whole, goes to constitute the final product.
The SACC Technology realizes audio loudspeaker with the superior quality compared to the traditional construction process and with characteristics of design and construction deprived of the ties to the classical methodology. Moreover, the way used to realize a loudspeaker through SACC Technology opens new future possibilities regarding the materials to use and to new constructive structures.
Using the SACC Technology with our private EA-HDR material we were able to improve many times the final performances of our loudspeakers. Our High Density Resin with Aluminum, special metal inside the cabinet walls permit to produce a best sound in terms of details and purity!
