Open Box ADAM Audio A77X Powered Studio Monitor Level 1 Right

In some setups, it can be advisable to use a horizontally designed speaker rather than a vertical one. Until now, such monitors were only available within ADAM Audio's SX top line.

The A77X dual 7" powered studio monitor, due to its outstanding features, might become a true game changer: Equipped with the same advanced technologies as the A7X, it therefore is very similar to the two-way speaker. The A77X, however, distinguishes itself by much higher, compression-free maximum sound pressure levels and dynamics. Due to its power and radiation characteristics, it also is perfectly suited for both near- and midfield monitoring.

Driver technology
Like all models of the AX series, the A77X features the ADAM Audio 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.

The two 7" woofers are identical with that of the A7X. With their large voice coils (1.5 mm) 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.

Amplifiers/Controls
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.
