Horn Speaker Recommendations

I also recommend AG. I was on a mission at Axpona this year for new speakers. I decided to ignore price, rank my top three then decide. The AG Duo Mezzo XD was my second choice over Magico, YG, Raidho etccc  all very good but lacked comparable dynamics. The XD has excellent bass along with incredible dynamics and imagining. I ended up buying  Gryphon Trident II which I considered best of show however I would have been very happy with the AG’s. Give them a listen.

I went through this very exercise over the last year.  The La Scala-II is fantastic and paired with a really good sub is full range bliss.  That being said I moved on to the BD-Oris-150 using the Voxativ AC-2.6 8" full range. I have kept the La Scala's but wow the Oris/Vox is unbelievable.  Using the compact-reference base system running on a Crown-K2 and active xover. Huge dynamics with accuracy. 

Hal9k...have you owned or heard the Odeon speakers?  If so, which one?  

You might consider a pair of  Klipsch Diamond Jubilees. Those could be had for under 20K. Use a good tube amp for the drive.
Or you might consider a used pair of  K horns, approx. 4-5K.
Then pick up an electronic crossover, I use a Crown VFX2 along with a good transistor amp for the bass with volume controls for sound tuning. (transistors are better for bass: tighter, faster...)
Drive the mids/highs with a nice single ended tube amp of your choice and you have reached audio nirvana my friend!
No need for a subwoofer with this setup, you'll have lots of nice, tight, deep bass

This is a crazy hobby that we have.   Here I am looking at $30-40k speakers for my new house, and then I think I have a loaded 2019 Mustang GT that costs less than $45k.   Somehow that does not make sense.
