Advice and help understanding, choosing a Widebander / Single Full Range Driver speaker?

With jazz, folk, girl and guitar, they are just about perfect. Add a SET amp, it is spooky real, band is playing in the room sounding.

@seanheis1 Thanks. What I am looking for!

I mean 250-400 Hz  , The deficit sound pressure make sound thin
Only real horn get big help  . transmission line working just for lower
bass.

I have had used full range speaker with 300B SET amplifiers for 4 years.

But it had lot of limitation in treble.

After I switch to Lansche 4.1, I had been happy with pristine treble that I can not get with full range.

This one is smaller model than mine.

But you can experience excellent treble out of plasma tweeter.

It will be very good for Jazz Vocal.

@shkong78 Thanks for bringing this to my attention.

Thanks to all who have contributed to this thread. Re-reading the thread has reinforced the wisdom and the on-point contributions shared in September and October of last year.

It's been a slow process, as expected, but with a ton of learning and growth as well as actual experience within/across portions of our hobby.

The Cube Audio Nenuphar speakers were delivered this past Wednesday and I am closing in on 100 hours of run time on them. I've been running them overnight on my solid state gear.

I also added the Grandinote Genesi Preamplifier ahead of Scott Sheaffer's Found-Music 2A3 amp. Since the Genesi is a fully balanced design, I am using a custom Cardas XLR adaptor to allow for 'correct' SE IC connections.

Jeffrey Catalano of High Water Sound has been and continues to be wonderful to work with and helped arrange an audition of the Horning Hybrid Eufrodite Ellipses through one of his clients. The audition was exceptional. The Eufrodite is a speaker I can see myself being very happy with and I am working on a follow-up audition. His client has recently added and broken in a Kuzma 4-Point 14" arm and an Air Tight Opus-1 cartridge and is getting fantastic results. 

Holger Adler of Voxativ has been tremendous as well. I am working on getting to Dallas to audition his full line. 

Axpona is a fall back option, though it may be tough for me to coordinate with my schedule.

I am also planning on a future trip to NYC/NJ to get my ears on Horning, Charney, Grandinote, etc.

@acresverde  Once the Cubes are broken in (which they are...I'm giving them longer than the 40 hours Jon Ver Halen, the Cube Audio U.S. importer, advised), and I've worked on placement/ positioning, etc. I'd love to get your opinion and feedback on them within the context of my system and room.

A MAJOR shout-out of thanks to Charles ( @charles1dad ) for his extraordinary support and guidance throughout the journey.

There are others who have helped in major ways, and I'll recognize all of you formally and express my gratitude once I get a mini-write-up organized.

The original articulated goals remain the same. To have a 'bifurcated' system. My front end through DAC remains the same. What may change is my full-range speaker choice. Horning Hybrids and Voxativ's full range 'system' or moving up the Tekton Design line are all viable options, as part of the 'two speaker' system journey.
