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.

The picture on the left 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, on the right,  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, on the left, and to a loudspeaker realized by SACC Technology, on the right. In the graphs we can see 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!

But we were able to improve the “almost perfect” SACC ...

The natural evolution of our “almost perfect” SACC Technology is the new SACC-2. Based on the previous concepts and philosophy the new technology join all characteristics of the SACC with the new EA-U.HDR material and with some little “elements” inside the chamber of the midrange and tweeter. Using these new elements we are now able to reach the highest performances in the the vocal range frequencies giving better feeling and quality in the music reproduction.

The previous SACC, today used in all other models, can cancels and avoids the generation of reflection waves and resonances inside the cabinet giving more realist sound and more speed in the midrange and high-midrange frequencies. And over all SACC permits to avoid the use of the damping material inside!

The new SACC-2 adds to the SACC’s characteristics another important element. Now SACC-2 is able to does all SACC does but joined with a small absorption thanks many small elements placed on the single slices. This different from the damping material action because these small elements don’t cover the walls inside but work together the SACC!

The new SACC-2 is the biggest improvement done in the audio market!
