best high sensitivity full range speak under 15k


I am looking at opinions on full range( ie down to 25hz), easy to drive speakers that can be driven by 60 watts or less, even SE. Do they exist?
or do you have to go to the big speakers that need SS and lots of watts to drive if you want full range. Something like my Vienna Mahlers would be an example fo this breed.

I have the Reimer Tetons and am using Lamm ML1's 90 watt push pull tubes. The Tetons go down to around 16hz. These speakers will give you full range sound and have a very flat response throughout the frequency range. They can be run on as little as 8 watts.
Forgot to mention, that I also had the VA Mahlers and replaced them with the Tetons. The Teton's have a deeper and tighter bass response than the Mahlers in my system.
Zu Definitions would fit into your classification of requirements for full range easy to drive speakers.
