ADAM Audio has announced a new model within the AX range of studio monitors. The A77X is a horizontal dual driver design suited to nearfield and midfield monitoring and includes the advanced technologies found in the A7X. The A77X, however, distinguishes itself by much higher, compression-free maximum sound pressure levels and dynamics. With their large voice coils (1.5”) and powerful amplifiers, they are capable of both very high maximum sound pressure levels as well as very deep registers. The woofers do not cover the same frequency bands: while both of them are responsible for the (sub-) bass frequencies up to about 400Hz, only one of them reproduces the midrange. This prevents interferences between the two drivers. Like all models of the AX series, the A77X features the ADAM proprietary 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 higher efficiency and higher maximum sound pressure levels.
Each driver has its own dedicated amplifier. A 50W A/B amp is responsible for the X-ART tweeter, while the bass-/midwoofers are driven by a 100W PWM amp each. The front panel includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.
The rear panel features 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
“Producer/engineer Ed Buller has installed ADAM Audio A77X monitors in his North London studio. Ed is long-time ADAM fan and has owned A7 nearfields for many years. ‘The A77X was perfect for my set-up. I love the top-end on ADAM’s and the unique tweeter means that I can listen at high levels for hours with no fatigue. The size and the sound of the A77X is brilliant, there was no other choice,’ he said.” - Resolution
