ZERO series:
ZERO 1 XD (instead of ZERO 1 and ZERO 1 PRO). XD changes: XD version will automatically feature the PRO and "normal" software, the analog input and a new "band-less" equalizer tool (software applet) that allows for finest adjustments regarding frequency and level settings (with graphic interface). A room adaption measuring kit is previewed for Q4-2015/Q1-2016.

There will be only one UNO XD model (instead of UNO FINO and UNO), exact size and pricing at this point to be determined! XD changes: new OMEGA type midrange and tweeter drivers, revised CPC crossover design.

With the launch of the XD Series line of speakers approaching, the speaker portfolio will undergo a profound change.
The XD versions will feature our latest and most advanced developments and technologies, which will
advance the speakers to a new level of quality and flexibility, and we strongly believe that this justifies a
completely new line-up of the UNO range.
Thus the new UNO range (available October 2015) will comprise just one speaker, the UNO XD, which
will feature the technologies that have so far been exclusive to the DUO and TRIO lines (proprietary
OMEGA technology drivers, patent pending CPC crossovers, 1000 watt XD subwoofer amplification, 10-
band parametric DSP bass control).
Production of the current UNO-G2 and UNO FINO speakers will cease by the 4th quarter of 2015.
The XD versions will feature our latest and most advanced developments and technologies, which will
advance the speakers to a new level of quality and flexibility, and we strongly believe that this justifies a
completely new line-up of the DUO range.
The new DUO range (available August 2015) will comprise the DUO XD and MEZZO XD speakers (PRIMO
XD available on special request), featuring technologies that will further outline the unique virtues of
our horn speakers (such as the 8 times greater dynamic range and 90% less distortion than conventional
designs, as approved by the University of Aachen/Germany), achieved by new proprietary OMEGA
technology drivers, patent pending CPC crossovers, 1000 watt XD subwoofer amplification, and 10-band
parametric DSP bass control throughout the line.
Production of the current DUO line of speakers will cease by the 4th quarter of 2015.
The new TRIO and subwoofer range (available August 2015) will comprise the TRIO XD and TRIO Classico
XD, partnered by SUB231 XD, SHORT BASSHORN XD, or BASSHORN XD. The XD technologies
will further outline the unique virtues of our horn speakers (such as the 8 times greater dynamic range
and 90% less distortion than conventional designs, as approved by the University of Aachen/Germany),
achieved by new proprietary low-mid drivers, patent pending CPC crossovers, 1000 watt XD subwoofer
amplification, and 10-band parametric DSP bass control throughout the line.
