APX 6.5 APX 6.5 features a concentric coaxial tweeter: with one single point of sound emission it is possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter. The 6.5″ cones surround features the exclusive shallow “Triple Wave” profile, for maximum excursion linearity. CompTwo way coaxial

AP 1 The AP 1 tweeter features a 26 mm diameter emission diaphragm, an acoustic lens designed to compensate for the frequency response within the 10kHz – 13kHz range, a Neodymium REN magnet and extremely small sized dedicated passive crossover

APX 4 APX 4 features a concentric coaxial tweeter: with one single point of sound emission it is possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter. The 4″ cones surround features the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.

APBX 10 DS The APBX 10 DS, a 10” subwoofer loaded in a 12-litres sealed enclosure, is the line’s “flagship”. It is dedicated to the highest performing Prima systems, using the AP1 D amplifier for the sub section. The speaker’s mechanical excursion of more than 18 mm provides for incredible authority, while the refined Thiele&Small parameters set-up provides the ideal balance for all music genres.

bit Tune SOUND TUNING TOOL The Audison bit Tune is a revolutionary system of automatic calibration for Audison bit processors developed with bit Drive technology. Bit Tune also includes a multitude of additional features for electro-acoustic verification and analysis of any car audio system. The Audison team’s goal in developing the bit Tune was to speed up the setting of basic parameters for the calibration of the bit processors (time alignment, equalization, levels, etc.), ensuring an excellent level of acoustic performance. This phase also includes the diagnosis of common “errors” (channel inversion/phase, no signal on one channel/cable, etc.) to set the specialist free from his “routine” work and allow him to focus on the art of “fine-tuning”. Only personal interpretation and experience can achieve what a machine could never do: create “Your Sound”!

AUDISON - Bit Ten D Bit Ten D is a multi-function digital processor conceived and built to process digital and analogue signal both on the input and on output to the amplifier (featuring AD Link connection) and create top-performance system with any source typology. Provided with a 32 bit, 147 MHz clock speed DSP as well as 24 bit A/D and D/A converters, bit Ten D processes the signal with extreme accuracy and wide configurability thanks to a software especially designed for car acoustic peculiarities. Bit Ten D features an optical digital input, minimizing interference and degradations of the signal found in traditional analog interconnects, also by-passing the A/D conversion phases of analog signals. Thanks to the AD Link connection, the available outputs become 8 in total, all in digital format; they can also be used simultaneously with the analog ones (for a maximum of 8 outputs total). The AC Link is completely dedicated to the “remote control” of the system. The system is comprised of one connector for the provided DRC and one for the amplifiers present in the system. The DRC is supplied with the bit Ten D product.
