as, at equivalent power capability, their mounting complexity is remarkably reduced.
1.2 Technological Solutions
The choice of AXIOM Systems project specifications was made considering the actual needs of our
customers, the final users. Analysing such needs and combining the results with our professional expe-
rience in this field we laid the basis for our project of building functional versatile vertical array systems.
We overlooked no detail. We privileged the choice of components that assured quality and reliability.
Every product was extensively tested before its actual industrial production. Each system set up was
studied both in labs and in the field, on stage during important national and international events.

1.2.1 Components

We accepted no compromise in the choice of components, woofers and custom drivers: we wanted high
performance when handling power and excellent audio features, nothing less.
AX3210P Systems feature a double-membrane, coaxial driver that, if compared with traditional single
membrane drivers, offers better muffling at the highest frequencies, resulting in an exceptionally soft
sonority for a professional component with such a high output. The two membranes in the driver are
piloted through a purpose-designed, passive filter. The coaxial driver is mounted on a wave guide with
a CAD profile which allows the correct wave front curvature and the correct directivity with respect to the
vertical axis, minimizing distortion effects and vibration.
Figure 1.6: AX3210P components: (a) internal detail of coaxial driver; (b) wave guide mechanical plan detail.
The compression driver features a neodymium magnet, a 1" throat and is equipped with a special
titanium membrane which enables it to work well even at 1.3 kHz despite its small size.
The wave guide, entirely built aluminium die-cast, allow to minimize losses whilst mantaining a very
high efficiency of the driver, in particular at the higher extreme of the audio band.
All woofers adopted for AXIOM Systems have been especially designed according to state-of-the-art
technology for moving coil transducers.
ISV (Interleaved Sandwich Voice) Coil; a coil wound around its bearing both inside and outside allows
better dissipation of heat and, consequently, power compression reduction.
SDR/DDR (Single and Double Demodulating Rings); demodulating rings minimize modulation effects
due to inductance and, as a result, harmonic and inter-modulation distortion are reduced through
the entire frequency spectrum reproduced.
DSS (Double Silicon Spider); a double spider improves excursion control and temporal stability of the
component features.
