I've used two pair of speakers with the Raven Blackhawk LE, Nola Boxer S1s that are 90 dB and currently the Reference 3A di Capo i. The di Capos are advertised as being 92 dB but SoundStage measured them at 89 dB.
The Raven will easily drive either to louder levels than I would ever want in my living room.
