ADAM will introduce its A77X monitor at Musikmesse.
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 improved, according to the company: the frequency response. It now extends all the way up to 50kHz.
The two 7" woofers are identical with that of the A7X. Their voice coils are 1.5". 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, ADAM explains.
