Evo nakon nekog vremena i kod sebe sam primjetio samo na jednom monitoru "simptome".
Iskren da budem, ocekivao sam na oba jednako! 
Serijski brojevi su im jedan za drugim.
Konkretno kod nizih/dubljih kikova i samo na dvije tri isproducirane stvari, ne sjecam se tacno sta je bilo u pitanju.
Kod kikova koji su bili bas,bas fat a kod tih par songova je bila zbilja jedva osjetno.
Ipak, kontaktirao sam support i odmah su reagovali.
"Hello Angel,
sorry to hear that you have a problem with one of your ADAMs. Both of your A7X definately have the new port design. By design, every basereflex system produces a kind of port noise ? but it shouldn?t desturb during normal work. Do you have already exchanged the speakers against each other? Just to make sure, that the room and your source have no impact to this phanomen. If you think your mointor is defective, we have to service it - in this case the normal procedure is that you go to your dealer, where you bought your monitors. They will tell you, how to proceed.
If you have any further question please feel free to contact them or ask me again!
Mit freundlichen Gr??en / Best regards "
E sad, mene interesuje da li se taj noise pogorsava ili je takav kakav je?
