I use to have Studio 40 v2's and have listened to the v3's. Paradigm addressed the harsh/bright tweeter but there is still some there. I would buy the v3's over the v2's. That is the only difference I could tell. Some people say the v3 does not have as much bass as the v2 but I think it is just a matter of break-in. My v2's took about 200 hours before the bass opened up. If you go to www.paradigm.com you can find the spec's on the v2's and v3's I believe.
Good luck,
Burton
