The ADAM A77X is a 2.5-way, mid- or nearfield monitor with dual 7″ drivers, X-ART ribbon tweeter, and 2x 100W amplification

There are those who say that truthful monitors are good because they’re hard to listen to, while monitors that are easy to listen to are not necessary good for mixing. ADAM thinks you can have both, and proves it with the A77X. A horizontally designed monitor combining of all the innovations in the AX-Series, the A77X offers compression-free sound reproduction and excellent radiation characteristics. However, that’s not the whole story. The A77X has dual 7″ drivers, one of which functions like a subwoofer, covering the frequency range from 38Hz to 400Hz, after which, the midrange driver takes over. Thanks to its high-power output, the A77X is suitable both for nearfield and midfield monitoring.

ADAM A77X Mid-/Midfield Monitor in one take:

  • 2 x 7″ carbon/Rohacell®/glass fiber mid/woofer
  • X-ART tweeter
  • 50W/2 x 100W amplification
  • On/off switch and front-panel volume control
  • Tweeter gain and 2 shelf filters on the rear panel
  • Frequency response from 38Hz to 50kHz
  • XLR and RCA connectors
  • 122dB max. peak SPL per pair
  • 5-year warranty

Dual 7″ driver technology

The unique feature of the A77X is its 2.5-way system. Both 7″ woofers work together at 38Hz, but at 400Hz, one woofer fades out and only the second continues to operate in the midrange up to 3 kHz. This prevents interference 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.

Worthy of note in the A77X is its extremely wide stereo field and brilliant spatial imaging—in essence, a sweet spot for days. Treble and mids are reproduced with three-dimensional realism, and thanks to its double-woofer designs, the lows are massive without compromising precision.

While the A77X can be vertically oriented, it’s designed for horizontal placement. When placed horizontally, it matters which woofer is on the outside. As such, the A77X has an A and B model for proper response.

Precision X-ART tweeter

The X-ART tweeter comprises a corrugated ribbon diaphragm, in which the folds compress or expand according to the audio signal applied to them. By folding the X-ART diaphragm a larger foil can be used, increasing the acoustically effective area of the diaphragm by a factor of more than 2.5 times over conventional dome tweeters. This results in higher dynamic output with extremely wide dispersion. With the increased surface area, the X-ART tweeter shows an improvement in air loading by a factor of 4 over conventional transducers, providing 4dB higher efficiency and reproducing frequencies accurately all the way to 50kHz. The linear response to 50kHz reduces in-band phase shift, which has a profound effect in the audible spectrum: less coloration, more realistic space and depth, and better perceived dynamic realism,

In addition, the X-ART tweeter’s folded membrane avoids the typical breakup/distortion and subsequent dynamic limiting at higher frequencies found in dome and cone tweeters. Another positive result of the X-ART design is that the driving ”stripes” are in direct contact with the outer air and are cooled immediately.

A/B Amplifier

Since the X-ART tweeter has an extended frequency range, it presents problems with the use of pulse-width modulation, or switching amplifiers, which are known for their efficiency. However, PWM amplifiers require a low-pass filter to separate the modulation frequency from the audio band, which in turn could limit the high-frequency reproduction capabilities of the X-ART tweeter.

ADAM engineers put considerable time and effort into creating a high-frequency power amp to allow the X-ART tweeter perform up to its abilities. The result was an ultra-low distortion power amp module that delivers an ultra wide response up to 300 kHz. With nothing limiting the X-ART tweeter, the monitor has unsurpassed clarity and openness which will satisfy the most experienced professional ear.

The tweeter is driven by a 50-watt amplifier and the bass/mid-woofers by a dual 100-watt PWM (pulse width modulation) amplifier. The amplifier produces a very clean reproduction of the midrange frequencies with a seamless transition in the crossover at 400Hz and 3kHz.

The ADAM A77X are not only a pleasure to mix with, providing accurate mix translation while reducing ear fatigue, they offer considerable bang for the buck. For more information, call or chat online with your Westlake Pro Sales Consultant today.
