The ADAM Audio BUNDLEA77XSUB1 is a studio monitor bundle with (1) A77Xa right monitor, (1) A77Xb left monitor, and (1) SUB15 subwoofer.


The A77X is a horizontally designed monitor that combines all of the technical innovations in the AX-Series. Due to its powerful, compression-free sound reproduction and excellent radiation characteristics, it is suitable both for nearfield and midfield monitoring.

The special feature of the A77X is its 2 1/2-way system. Both 7” woofers start to work together at 38 Hz and at 400 Hz one woofer fades out and only the second woofer continues to operate in the midrange up to 3 kHz. This prevents interferences and possible phase cancellation in the critical midrange. Even though frequency transitions and potential distortions lie outside these areas, the human ear is particularly sensitive to midrange frequencies.


Especially noteworthy in the A77X is the extremely wide stereo foundation and brilliant stereo imaging. Treble and mids are reproduced with three-dimensional realism and the lows are, as expected from a double woofer design, massive without compromising on precision.


The Sub15 is an extremely powerful subwoofer capable of extending the frequency range of main and midfield monitors down to 20Hz. The sturdy 15" woofer is made of an exceptionally rigid aluminum membrane and is driven by two powerful magnets and a 100mm voice coil. With 1000 Watts (RMS) power capability, the PWM amplifier has an efficiency factor of nearly 90%. With these performance features, the Sub15 is easily capable of handling critical musical passages with intense and sudden bass peaks without showing signs of distortion or overheating. The downward firing bass port has been specially designed with ample dimensions and rounded edges to cancel any port noise.
