Adam Professional Audio A77X
The A77X features an X-ART tweeter, new woofers and amplifiers, and completely re-designed speaker cabinets. It is equipped with the same advanced technologies as the A7X, but it produces much higher, compression-free maximum sound pressure levels and dynamics. Due to its power and radiation characteristics, it is suited for near- and midfield monitoring. The "X" stands for "eXtended frequency response" and the Accelerating Ribbon Technology has been improved in terms of frequency response that now extends all the way up to 50kHz. The A77X's two 7" woofers feature 1.5" large voice coils and powerful amplifiers. The woofers cover different frequency bands: one handles the (sub-) bass frequencies to approximately 400Hz, while the other reproduces most of the midrange.
