Narrative:

We were vectored onto final approach for a visual approach to 9R at atl. We joined the localizer at a lower altitude than the aircraft ahead of us. Well outside the marker; we encountered two noticeable wake turbulence events. The aircraft remained on autopilot for the duration of the sequence of the wake turbulence encounters. After the second wake encounter; the autopilot was disconnected and the aircraft was hand flown for the remainder of the approach. The maximum bank angle was approximately 25 degrees during the sequence of events. We were stabilized and configured well prior to the final approach fix. Cause: ATC vectored us onto the approach below the aircraft that was preceding us. This caused us to encounter wake turbulence that could have led to an aircraft upset and potentially loss of control.
