calling all Guru;s, Ideas on audiophyle high effeiciency speakers solicited


Wanting to enter the "Tube system" realm. After extensive research I've come to realize that my current low efficiency speakers B&W 803D2 require a lot of power and may not cut the mustard using tube gear. Although I truly love the speakers I may end up swapping them out in the future to accommodate my new found rabbit hole. Tube amps in general provide only minimal power certainly not enough for my listening habits. 
Anyway what , by any standard, constitutes a high efficiency speaker? is it a rating of 80....... 90, 92,......97? just what is it. Do speaker manufacturers fudge the number on occasions? How do we know? Is a 2 way design inherently more efficient than a 3 way? Does  the amount of speakers in a cabinet affect efficiency?
Last of all what are some audiophile grade speakers?

High eff is over 100db medium about 90+db up ohm load also effects ability to drive and must be considered. Most high eff designs use large cone area many need to be multiway over 3-5 way depending on end goal and range required. I would suggest you select tube amp maybe list budget system room and over all system goal you wish to achieve if you want more detailed information. I would say pursuing higher efficiency can be a laudable goal and can yield incredible sound over conventional systems but users need to have a bit more knowledge when selecting such over what one needs for standard audio fare.
