Points Im about to make are expressed in many online reviews, so Im going to be short. Speakers are kinda bulky in size, compared to Yamaha, but they also have 0,5" bigger speaker. Volume knob is in the back, and 0dB position is on a weird spot (like 2 o`clock) and with NO NOTCH, so its difficult to know where you are. There are HF and LF +/- 2 dB corrections and a power on light IN THE BACK, which is just not practical.
Very well build, no problems here.
Here we go. A lot of people find this monitors to be more like Hi-Fi than monitors, and I agree. When you compare them to Yamahas and listen to some produced music, they sound lively and not dull in comparison. But when you mix music and compare to Yamahas or different speakers (car, headphones,...), you see that Adams portray mix much nicer than it really is. On them, guitars sound rich and full, bass is just at a right spot, drums are very articulate and so on. But other sources show that guitars are dull, bass is to low because Adams project too much bass, drums get covered up and so on. Yamahas show all that, and those corrections in the mix would be possible listening on them.
So in conclusion, Adams are great for producing to give you a nice feeling when composing. For mixing, I wouldnt pick them over Yamaha HS7 in this price range. Feature flaws are kind of embarrassing for company like Adam, but the build quality is very nice. Maybe EDM and hardbass guys find these monitors usefull due to extended bass range, but for a guitar/drums/bass/vocals music I dont reccomend them.
