The first aspect that distiguishes the ADAM A7X is the X-ART tweeter. The 'X' stands for 'eXtended frequency response' and thus for one of the features of the Accelerating Ribbon Technology that has been drastically improved: the frequency response. It now extends all the way up to 50kHz. In addition, the X-ART tweeter has a higher efficiency and higher maximum sound pressure levels.
The perfect integration with the lower frequencies has been achieved with a 7" midwoofer. It has been redesigned with a much bigger voice coil (1.5") and is driven by an amplifier with twice the power compared to its predecessor. This combination produces an amazing sound and pressure levels with an almost distortion-free musical reproduction.
Each driver has its own dedicated amplifier. A 50W A/B amp is responsible for the X-ART tweeter, while the midwoofer is being driven by a 100W PWM amp. The front panel of the ADAM A7X includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.
On the rear panel of the ADAM A7X are several additional controls: a gain for the high frequencies (-¦ 4dB) and two shelf filters for high and low frequencies. To ensure greater compatibility, there are both XLR (balanced) and RCA (unbalanced) connectors.
