  • Adam Audio - A8X Nearfield Monitor 2-way, 8.5" woofer
  • Adam Audio - A8X Nearfield Monitor 2-way, 8.5" woofer



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.

Features & Benefits

  • 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 
    • Unbiased reproduction in a very wide frequency band
  • Maximum peak sound pressure per pair in 1 m ≥ 120 dB 
    • Powerful, compression-free sound reproduction even at very high sound levels
  • Simple, stepless room acoustic adjustments over tweeter gain, low and high shelf filters 
    • Allows optimal adaptation to acoustically difficult listening environments
  • Analog XLR and RCA inputs 
    • Optimized for balanced and unbalanced line signals
  • Acoustically optimized cabinet geometry 
    • Reduction of unwanted reflections on the cabinets
  • Directional sound radiation in vertical plane 
    • Reduction of early reflections on the surfaces of, e.g. mixing consoles, desks, etc.
  • Volume control and on/off switch on the front 
    • Very easy to use
  • 2 years warranty with optional extension to 3 years with the registration of the product 
    • Full repair service if required for 5 years
