Any experience with the Infinity Primus P363?


I am considering the purchase of a pair of these speakers for a secondary system. Need something that is an easy drive for a Dynaco ST-70. The P363 is rated at 93dB and 8 ohm. Received a great review by Robert Greene in TAS.

After doing a google search it seems that this speaker may be a 4 ohm speaker, at least based on the measurements by one reviewer. I am looking for a speaker that doesn't drop below 6 ohms across freq range. I will research further.
