|Adam Audio launched the A77X monitor at Prolight+Sound 2011, Frankfurt and made its US debut at 131st AES convention, New York. The A77X features the company’s X-ART tweeter, new woofers and amplifiers, and completely re-designed speaker cabinets.|
The brand new A77X is equipped with the same advanced technologies as the A7X. The A77X, however, distinguishes itself by much higher, compression-free maximum sound pressure levels and dynamics. Due to its power and radiation characteristics, it is suited for both near- and midfield monitoring.
Like all models of the AX, 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 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.
Adam's AX-Series used to include four high performance systems, ranging from the compact and fully professional A3X, to the high performance A5X, A7X and A8X systems. All models feature the new X-ART tweeter. In addition, the woofers and amplifiers have also been re-engineered from scratch, with larger voice-coils and more powerful amplifiers for greater linear excursion and more output. In some set-ups it can be advisable to use a horizontally designed speaker rather than a vertical one.
The two 7” woofers feature large voice coils (1.5”) and powerful amplifiers. As a result, 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 one of them is responsible for the (sub-) bass frequencies up to about 400Hz, the other takes over most of the midrange.
