10K$ Speakers for 845 SET amplification


Hi ,

I'm looking for speakers for my new customer made amplifier.
They are tubes of course:)
211 is driver , 845 is the power.
26 watt of sweet deep sound.

Would love getting 3,4 candidates for 10k$ (used only) ,
1.high efficience
2.Deep bass - usually those high efficiency speakers have some "light weight" bass ,i love deep with fast attack sound
3.MID - most important - can consider even horns .
4.3D Stereo sound - Somehow the high efficience speaker i ahd (La Scala , L300) was suffuring from bad bad bad imaging , It was nice ambient sound but u couldn't tell what is the middle where is the guitar and etc...

Thanks for suggestions

What about the JBL K2 models?
DO u think they will work with 845 SET amplifiers?
Used Avantgarde Unos or (perhaps) Trios can be had in that price range. Full range and 100-107dB sensitivity.
Again, a recomendation for Daedalus. I use the DA-RMA's, similar to the new Athena and they worked well with my Viva Solista, 845SET and now, the 20watt Ayon Spark. About 96db sensitivity and a benign load. I understand they would work with 8 watts, but something north of 20 watts would give better control
