What speakers work with low wattage class A amps

Hi everyone. I am setting up a system and have been really impressed by some low volume listening I was able to do through a class A amp. Class A amps usually have lower watts in a given price range, and are not as practical for big power. What speakers have sensitivity that would make sense for an amp with 25 Watts or less (eg some of the entry level class A options from Pass Labs)?  Are we limited to horn speakers? The speakers I have are said to require “high current amps”. Is this a factor as well? Thanks for your help.

The Harbeths as a group are very efficient and a favorite among the Harbeth users. I have 2 pair of p3 xd and 30.2 demo if you might be interested. Don

Altec-Lansing 604-8G drivers in a 620 9cf cabinet. Classic that will sound good with 25 watts or less.

Reference3A DeCapoI.  No crossover electronics that waste power.  Just a high pass cap for the tweeter,  The Midwoofer is allowed to roll off naturally.

Relatively large cabinet for a stand speaker.  And the midwoofer also is relatively large.  Both characteristics combined yield excellent bass.

I drive my DeCapos with either a 25wpc OTL tube amp or a 35wpc Musical Fidelity Class A.

Sound magnificent, most musical I have ever heard except for ProAcs.  But the ProAcs need a lot of power and the DeCapos do not.

Zu, Tannoy, JBL, Klipsch, Fyne..something with +90dB sensitivity

Not all models by the above brands may be high sensitivity but I believe that they all of them do produce some models that are. The all new Martin Logan "Motion" series are all +90dB and they appear to be significantly improved.
