I have the the Proac Studio 140MK2 for a month and I am very happy with it : the sound is balanced ,neutral , natural and detailed . it took about 2 weeks of " running period " to open up and show what they are really capable to do . I didn't tried to listen to the Response D18 because I read
that the bass is weak and I really like the bass dominant in my system also I didn't try the D2 beacuse I thought that standmount speakers
can not preform as good as floorstanders speakers in the bass area . Now I have some second thought maybe I made a mistake not to the demo
the D18 and the D2 as well ?. Which one you think is the best option ?
