Please Recommend Highly Efficient Floor Standing Non-Horn Speaker Suggestions

Apologize if this is redundant but the threads here all seem to recommend horn speakers for tube amps.

HMMMM maybe there's a reason?

Since no price range was mentioned:
Arion Apollo 105db efficient AMT line array but are 4 ohm. 

Omego Audio in Ct . 

Strictly speaking “highly efficient” means more than 100dB sensitivity, and there’s no way around that sans horns - indeed we’d be in all-horn territory here. If the 90-95dB sensitivity range will suffice - that is, it seems it must - that are some options. Have you considered Daedalus Audio?

Check out Reference 3A  i use their standmount speakers with my 4 watt tube amp Decware mini Torii and if it nice and loud in a 12 by 20 room

Flies under the radar as a Canadian company, but Verity Audio makes some of the best speakers I’ve ever heard and are also high efficiency.
