Many people seem to complain about the ability of the cc-370 v.3 or v.4 to handle lower frequencies. If, you use a X-over setting of 80 Hz, then personally I am not sure where that is such an issue. I use to own a cc-170 v.3 and thought it was a decent center. Furthermore, the cc-370 v.3 or v.4 is definitely a better sounding center speaker than the cc-170 v.3. To date, I am still mesmorized by how well the Atom v.3 or v.4's sound--truly "giant" killers. All in all though, it is still worth mentioning that the Studio series is CLEARLY a huge step-up from both the Performance and the Monitor lines all across the board. Anyways, hope this helps.
