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?
