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.
