A list of efficient speakers at ~$5K a pair.

As a follow up, I should have stated approximately $5000.

I would think Tekton is capable of squeezing into that suit.

Only 92db?? That’s not very efficient at all.

Try these very audiophile speakers. Put them on your highest fidelity dacs and amps.

Yamaha CZR-12, Price: ~2k/pair

Sensitivity 1W/1m: 97 db (passive)

8 ohm

Pioneer XY-122, Price ~6k/pair, but, you could beat it down to 5k with the dealer

Sensitivity: 101 db

8 ohm

Specifically I am searching for those speakers possessing a relatively flat 8ohm impedance curve and a true (8ohm) 92db sensitivity that are at a cost of $5000 USD.

I currently own Fritz Carbon 7s SE MK2.

The Reference 3a mm de Capo meets those specs, and they are excellent performers.  If you’re open to used you could step up to the Taksim tower model.  Best of luck. 

Well, I agree that 91dB is not that sensitive, however coupled with a flat 80hm speaker with a rather narrow phase angle makes for a pretty efficient speaker to my thinking.

What I failed to do was describe my listening environment. Basically a dedicated room treated to my liking that has the volume of a ~12x15' roo
