Thankfully the Hawks (according to Totem) have a 88db sensitivity (but no other units are given as far as distance or voltage), because I've seen some Totems of the past with extremely low sens like 81-82.
And they used to have lot of Dynaudio drivers in their speakers, yes? I think those drivers were actually supposed to be pretty robust, but I don't know if it would be the rest of the speaker design that may have led to your impressions.
Anyways, my impression was that older Totems nearly required robust amplification, if perhaps not for the Hawks.
