Recommendations for against the wall high efficiency speakers

I’m a believer in synergy, not individual components.   I’m setting up a new system in my condo and like most condos, I’ve got some limitations.   My room is 16’ wide and 35’ long, 9’ height.   The system will be placed 2/3 down on the long wall.   It’s the living room and my wife says no ugly room treatments as it’s our living room.   Just to head this off - I don’t need a new wife.    I listen at moderate levels (usually 70-85db).   Mostly progressive rock and jazz, all streamed, no phono.   Budget is $8k, for used speakers.   Once the speakers are mostly set, I'll work on amps, preamp, DAC, streamer, & cables ($25k all in budget, all used components).


The speakers will need to be placed right up next to the wall, so I was thinking of Ohm or Larsen, but these aren't very efficient – are there other options?   I’d like much higher efficiency as I like the dynamic presentation I generally get with that setup, but I don’t know of any efficient speakers I can place next to the wall.


I can add subs, if necessary, but I do need to take into account my neighbors above and below me.


I should add that historically, I've really preferred the sound of dipoles or open-baffle designs, but I don't have the space for them here.


Any suggestions or recommendations for my new-to-me main speakers?


Also, why of they have to be high efficiency? There are lots of high power amps for not much money that can give you dynamics.

@roxy54, Interesting idea.   I've not heard the Audio Note, but they are well reviewed.   I'll see if I can find a pair to audition somewhere.


@rar1, I love Zu and had not thought about them.   Can they be placed up against the wall?   I've only heard the Druid 5 out in the room a ways, and figured that ruled them out for me.


@paradisecom, I used to own a pair of La Scala's way back in the late 70's.   I loved them, particularly after I modded the crossovers and adopted the new (1980) mid driver.   They would be too large, but the Cornwall IV...   Hmmm.


@hedwigstheme, they don't have to be high efficiency, I just generally like the sound and dynamic contrasts of high efficiency speakers.   I've never heard of Gradient revolution, but I'm looking them up right after i hit send on this reply.


Thank you all.

Definitely should check Audio Note Speakers. If you would like their speakers , Audio Note has some great sounding Integrated amps like the Oto and the Soro to go with their speakers. They also make fantastic DACs like the DAC 2.1x Sig and the DAC 3.1x/II Balanced. Audio Note makes everything ,so you can even try their cables.
