Best monitor's in this price range, Frequency response is real good. I just use 5-8% of the total volume level in a 10x9 room & it already explodes my room. The acoustic compensation on the back panel helps a lot with acoustically treated & not treated rooms. The best part about this monitors is there's no pop's / clip's while turning it on or turning it off. The build quality is nice, the kevlar mid drivers produce enough of low end which you need in your mix! The silk dome 1" tweeter produces crystal clear High freq! Very accurate sound with no brightness in neither Low end or High end. It's a must buy product if you're looking for a monitor in the range of 40-50k.
