Suggestions for high efficiency speakers?

@fosolitude yep.  I am sure we met at CAF 2019.  
 

Avantgardes are a pain to setup.  With the powered bass, you have a ton of flexibility in terms of DSP to get the bass just right and timed perfectly but by extension it is not speedy and super easy.  
 

Placement though is a breeze.  For demo, when I have them setup here I have the left speaker tucked into a corner.  Because of its directional nature they are easy to get into a room.  Corners, windows.  No problem.  
 

There are exceptions within the line though.  There is a ported Uno, the Uno Fino, is actually quite difficult to place but that is more the exception rather than the rule.  

@psag ,

Thanks for the link. I wasn’t aware of the field coil option for that Musical Affairs model. Available as a 16 ohm load option, nice. I bet this speaker sounds fabulous! The vast variety of choices in High End audio is truly admirable. So many ways to make that Art Audio Jota SET amplifier literally sing!😊

If you can find field coil speakers audition them.

We recently played around with the Horning speakers - excellent mid-range.  That being said, just because you put a low wattage tube amp with them does not mean sonic beauty.  The 845 and 45 tubes make a big difference that just any low powered tube amp.

+1 on Klipsch and BorderPatrol.

I second with Volti. Additionally have you considered Devore 096? Only 96 in efficiency. Oh.. perhaps the DeVille Fleetwood loudspeaker  They offer a trial period  

Best luck!
