Cube Audio or Charney

I really like the Charney speakers, and I also like the Nenuphar speaker too.  I don't think I can attribute what I like to the lack of a crossover, but, that certainly is a possible reason why they both sound so good.  I think I could live with the Charney, particularly with one of the better AER drivers in it.  

But, I own a three way system that, on balance, I like even more than either of the speakers mentioned above.  Yes, it costs far more than either speaker (the midrange horn/compression drivers alone cost more than either systems), and it is certainly not better in all respects and I can easily understand why someone would prefer either of the two models under discussion.  My system is 99 db/w efficient, so it has not suffered too much from loss of efficiency from having a crossover.  A friend has a three way horn system that is 107 db/w efficient.  A crossover does soak up some power, particularly if it is complex and it is used to correct phase/timing and to correct frequency response anomalies, but, utilizing drivers optimized for performing over a limited frequency range has its pluses.

Why don’t more speaker designers embrace the crossover less concept ? 

mozartfan, there is no such thing as a loudspeaker without compromises.
There are so any ways to skin this cat. Given the variance in taste and the multitude of solutions it is no wonder we have so many opinions on the subject. I prefer simple solutions, fewer drivers and crossovers so, full range speakers are very attractive however there are so many factors involve such as linearity and uniform controlled dispersion that are extremely difficult for one driver to encompass. Crossovers become a necessary evil. I have heard speakers with crossovers succeed in achieving the absolute sound...twice. The only full range loudspeaker I have ever heard get there is a full range, line source, ESL. The compromises being size and low bass. Low bass is solved with subwoofers. Size is solved by divorce. 
Please, I would love to see you come up with a loudspeaker that has no compromises. Show me a person who thinks he has a speaker with no compromises and I will show you a person with bad hearing.

I own the charney companion Excalibur with voxitiv AC 2.6 (12,100.00) out the door…I HAVE MANY DIFFERENT amps and preamps to try on them my fav is the worlds most perfect monoblocks the quicksilver triode 6c33c’s with the music first passive v2 preamp and have a second room with the MERLIN VSM mme (13,000.00) all duelund equipped BAM and my fav is the atmasphere m60 mono block otl amps with the hattor pre all duelund equipped ……which is my favorite room???….. well…let’s put it this way …I would not want to give up either room do I have a fav room…depends on my mood
