these are KRK's but the VXT series. Its krk's high end line. I have them, the VXT 6's are excellent and they go as low as 49hz. They are really crisp and if you but them on isolators you can really hear where your bass is sitting in your mix nicely. They are fantastic for listening and even having a room party because of how nice they sound, but even these are slightly flattering. These here would set you back about 650 CAD, if you have a grand you could get a new pair of of CMS 65's which are the golden standard right now Im told by two friends (one who works at a studio and runs his own mastering gig at home with a pretty impressive hardware summing chain).
These will set you back about 500 or 600 USD a peice i think?
The guy that recommended them recently got signed to Hospital records and has been doing a lot of the mastering work for up-and-commers in the city here for a few years.
