What is your favorite High EFF speaker


Hello Everyone!


The most interesting item on my horizon lately are high efficiency speakers. 


Better said, speakers which can easily be driven by amps whose output is from 15 to 70wpc. And likely lower, ala 300B  amps, or a pr of Els or KTs, etc. there are a ton of 30 to 75wpc tube amps out there that perform at fascinating levels, and are very interesting. 


Having exactly no EXP in this realm other than a former interlude with Silverline Sonata IIIs (reputedly 93db, @ 8 ohms) some time back, I’m asking for members EXP on current or  recent production  speakers  still available you have used which check all the boxes IYO.


 imaging, resolution, bottom end accuracy, impact and honesty.


I listen to sensible  music. Nothing urban or inner city, rave, etc.., but I do enjoy twisting up the ‘fun’ knob on the preamp from time to time. 


Many thanks.

Not efficient but easy load not huge or bulky and amazingly one of best of show last year off a low watt headphone amp: Fritz Carerra.
My favorite is the Rethm Saadhana (101 dB)  I have owned the Maarga also.  My other speakers have all been in the 85 dB range.  I would say you will obviously have to listen for yourself, but I think you cant go wrong with a good horn.  I like the Rethm as they have built in powered bass for the lows, have a small footprint, are aesthetically nice (IMO) and the sound is heaven.  Currently driving with a First Watt SIT-3 and getting a AUDION Super Sterling KT120 SE to demo (for a tube experience).  
I've used klipsch heresy iii with a 12 watt set amp and I think they sound great.  Not enough bottom end for some people but you can add a subwoofer.  Currently using forte iii with a 22 watt set amp, and they rock.  Reviews on Devore orangutan 0/93 and 0/94 are excellent, but they're pricey.  I've ordered a pair of zu audio dirty weekend omen 2s and am looking forward to listening to those as well.  All of these speakers are 98db or higher, so they would be considered high efficiency.
