NB One speaker is boxed and new, the second is boxed but has been repaired and has some surface damage.
"The A8X is a powerful link between ADAM’s AX Series and the formidable and more expensive SX Series. Its all-in-all homogenous tuning, the deep and precise bass as well as the brilliant mid- and high-frequency reproduction make this speaker a huge recommendation." (Harald Wittig, Professional Audio) http://www.adam-audio.com/en/pro-audio/products/a8x/description
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.
