Suitable for both nearfield and midfield monitoring, the Adam A77X horizontal active studio monitor offers superior stereo imaging and great low end response. The A-Side and B-Side speakers can be stereo paired for optimal waveform dispersion in any acoustic space.

PWM Amplifiers and X-ART Ribbon tweeters offer unparalleled clarity and performance

The special feature of the A77X is its 2.5-way speaker 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. As a result, ear fatigue is reduced and a much more accurate stereo image is produced.

Adam A77X Key Features:

  • German Handmade Precision X-ART Tweeter
  • 2 x 7“ Woofer (Carbon/Rohacell/Glass fiber)
  • Amp. Power RMS / Music: 250 W / 375 W
  • Frequency Response: 38 Hz - 50 kHz
  • Max. SPL per pair at 1 m: 122 dB

Optimised Bass Tuning

The chambered upper corners of the sturdy cabinet fronts minimize edge diffraction so that phase cancellation is not an issue. The speaker interior is equipped with a special fleece that prevents disturbing internal resonances as well as ensuring a better bass reflex tuning.

Ribbon Tweeter Technology

As with other models in the Adam AX Series, the A77x features the X-ART Ribbon Tweeter technology - one of the most dynamic and accurate high-frequency tweeters available to date. The precise transient response and capability of reproducing every detail of your music make Adam Audio the only choice for professional engineers and producers around the world.
