ADAM Audio A77X Active Studio Reference Monitors (Pair)

These active 3-way studio monitors from Adam are simply sublime! The A77X features a ribbon tweeter and 2 x 7" low frequency drivers. Extremely clean sounding with very low distortion, even at high SPL. 
The A77X is a horizontally designed monitor that combines all of the technical innovations in the AX-Series. These speakers are great for a mid sized room. 


        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.
