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.

Zu Definitions would fit into your classification of requirements for full range easy to drive speakers.
Von Schweikert DB99. Designed for low power driving such as by tube amplifier. Superb.
Devore Silverback References. Full range (21Hz to 40kHz), stable 8 ohm impedance, 91db efficiency, $14k. They replaced a pair of Vandersteen Model 5s in my reference system. They sound wonderful with tubes or solid state. I've stepped off the updgrade merry-go-round.
Check out the new Bastanis Apollo, i heard them at RMAF, they sounded incredible.
