The SIGMA series is an active speakers Line, with digital Multi amplification composed by two speakers and one subwoofer. Sigma S115, woofer 15" and 1.4" driver, Sigma S215, double woofer 15" and 1, 4" driver, Sigma S118 subwoofer with 18" woofer. SIGMA series speakers are realized with Hybrid Enclosure Technology (H.E.T.), developed in the dB Technologies labs. The box in fact is made in light multilayer wood, coated in PVC with protection frames on top and bottom in polypropylene. The speakers of SIGMA series use digital amplifiers DIGIPRO G2 of last generation, power supplies featuring switching SMPS (Switched-Mode Power Supplies) technology which can delivering 1000W and 1400w to satisfy each kind of application. These highly efficient amplifiers provide high power with limited weight. Thanks to the low power dissipated, the cooling of the amplifier module does not require a fan. The digital preamplifier with DSP (Digital Signal Processor) controls the audio crossover of the acoustic components, the frequency response, the limiter and the acoustic phase alignment.
In the S115 and S215 speakers, a selector placed on commands panel, enables to select one of two different equalizations, "FLAT" and "BOOST", to assure high versatility for the different applications. In the S118 subwoofer, selector placed on commands panel, enables to select between two acoustic crossover frequencies: "80Hz" and "100Hz". The S215 bi-amped active speaker is equipped with a DIGIPRO G2 amplifier delivering 1400W. S215 is a quasi 3 way typology speaker, with two woofers 15" (voice coil 3") and compression driver 1.4" (voice coil 2.84") on a 60 Degree x 40 Degree aluminum CD-horn. The speaker's horizontal directivity is 60 Degree by default factory setting. The phase plug attached to the front of the upper woofer avoids the vertical phase modulation which usually take place in this type of configuration and ensures a precise horizontal coverage of the medium frequencies. The speaker is made of 15mm light multilayer wood, coated in PVC with protection frames on top and bottom in polypropylene; the four handles located on the sides of the speaker enabling easy transportation. In the bottom of the box there is retractable adjustable foot (in height) to inclinate the tilt angle up to a max. of 7 Degree. This allows to direct the sound radiation without using additional supports.
