Thank you very much for the additional information, jpearson3131.
I suggest the Larsen 8 or Larsen 9 as candidates for your situation. Here is a review of the Larsen 9; the reviewer is a concert violinist (whose day job is high up in the math department at UCLA):
https://www.theabsolutesound.com/articles/larsen-model-9-loudspeaker I have no experience with the Sonus Faber Olympicas but my instinct is that they are designed to be placed well out into the room. They might well have too much bass up against the wall, and their relatively narrow baffle implies that a fair amount of midrange energy will wrap around and reflect off the wall behind them.
The Devore O/96 looks more promising to me, as the wide baffle makes them less susceptible to negative interaction with the wall behind them in the midrange region. I’d suggest that you try plugging one of the two rear-firing ports, which would lower the tuning frequency and make the bottom end’s native response synergize better with placement up against a wall.
If by any chance you are open to used speakers, you might consider the Snell Type A, preferably in one of its later iterations. You might need to invest in some refurbishing as they haven’t been made in decades. But the Type A is one of the most well thought-out up-against-the-wall designs. That being said, the Larsens will probably give a better soundstage for off-centerline listeners.
If you are willing to go off the beaten path somewhat, PiSpeakers offers designs which work well up against the wall. The GedLee Abbey comes up for sale used occasionally, and is imo (along with the Summa) among the most acoustically advanced designs ever, though subwoofers are required. The GedLees and PiSpeakers can be toed-in aggressively to give very good imaging across the width of the couch. The JBL 4367 is also a candidate. These are all rather large loudspeakers, which may be an issue.
My other thoughts about speakers for your situation involve products that I’m commercially involved with.
But let me at least suggest that, in this price ballpark, it might be worth attending an audio show where Larsen will be exhibiting, or traveling for an audition. They have a dealer in Los Angeles. No affiliation.
