ADAM Audio A8X

The A8X adds to the AX-Series as a unique model because its power and radiation characteristics allow it to be used as both a nearfield and midfield monitor. It represents a particularly attractive entry-level model for midfield monitoring which offers transparent reproduction of higher frequencies, clear mids and an excellent transient response.

The extra large, front-positioned bass reflex ports are perfectly matched with the bass/midrange driver that has a 1.5″ voice coil. Thus the A8X can play very low registers with a powerful punch, and the greatest possible precision. The 150 Watt PWM amplifier for the midrange speakers in conjunction with the 50 Watt A/B tweeter amp enable the A8X to generate impressive maximum sound pressure levels of 120dB per pair at one meter.

German Handmade Precision X-ART Tweeter

8.5“ Woofer (Carbon/Rohacell/Glass Fiber)

Amp. Power RMS / Music: 200 W / 300 W

Frequency Response: 38 Hz - 50 kHz (-10 dB)

Max. SPL per pair at 1 m: ≥120 dB

The A8X is no longer being produced. Please have a look at its successor: The ADAM Audio A8H!

With an absolute transparent reproduction of the high frequencies, a good midrange and an excellent pulse fidelity in the lower frequency area, the A8X shows its abilities as a very capable nearfield monitor. Workmanship and design is, just as expected from ADAM, top-notch quality.

Its performance is comparable to much more expensive mid-field monitors (…), the A8X will seduce the masses effortlessly!


The winner of this test was the A8X from ADAM Audio that showed excellent linear sonics and a solid build. (…) Complex orchestral recordings were well structured and single instruments easily identifiable. All in all it offered a very precise soundstage. This astonishing soundstage and detail is due to the tweeter that is powered by its own amplifier. What impressed us was how our Flamenco dancer could literally be heard turning in perfect circles. Impulsive kettledrums sounded dry and powerful, this being due to the 8.5” mid/low woofer and the cabinet dimensions.

Features & Benefits

Product Feature
Benefit to the customer
X-ART tweeter, handmade in Berlin
  • Allows longer operation with fewer signs of fatigue
  • Their breakup is prevented by the folded diaphragms, distortions are effectively reduced to a minimum
  • Advanced dynamic range due to acoustically effective diaphragm surface that is 2.5 times bigger (compared to a classic tweeter according to the piston principle)
The air velocity ratio of 4:1 during the sound generation by folded X-ART membrane

Direct, fast response in the high-range even with complex transients

Ultra-light but extremely dimensionally stable woofer material (Carbon/Rohacell/Glass fiber)

Excellent transient response even at high sound levels without breakup of the diaphragm

Vertical 2-way system with 8.5” woofer

High resolution of the stereo image

Spacious bass reflex ports on the front
  • Bass reproduction with very low compression
  • Allows positioning close to walls
Highly efficient PWM amplifier for the woofer coupled with an A/B amplifier for X-ART tweeter

Low-distortion amplification at both low and high volume levels

Linear frequency response of 38 Hz to 50 kHz (-10 dB)

Unbiased reproduction in a very wide frequency band
