Egglestonworks Andra II: How difficult a load?

I'd like to upgrade to these speakers. They will be paired with Cary CAD 211 AE monoblocks in a 20ft x 25ft room. Will I have enough power to drive them given their 4ohm load with 89dB efficiency? I like to play loud rock at times, although I mostly listen to jazz/blues/pop at moderate volumes. Unfortunately, I'm buying used and I can't audition them with my amps.

Thanks all.
