Why Aren't More Speaker Designers Building Augmented Widebanders?

Over the years I've owned a number of different speakers - KLH, Cerwin Vega, Polk, Opera Audio, Ars Aures, and Merlin VSM. One thing they all had in common was a crossover point in the 2000 hz (+ or -) range. I've read reviews of speakers where the reviewer claimed to be able to hear the crossover point, manifested as some sort of discontinuity. I've never heard that. My Merlin VSM's for example sounded completely seamless. Yet my new Bache Audio Metro 001 speakers, with a single wideband driver covering the range of 400 hz to 10,000 hz, augmented by a woofer and a super tweeter, sounds different from all of these other speakers. The midrange of the Bache 001's is cleaner, more coherent, more natural than I have heard before. Music flows from the speakers in a more relaxed manner, and subjectively dynamic range is greater, with no etch or brightness, and no loss of resolution compared with the Merlins. I have to conclude that Bache's design has an inherent advantage over more traditional designs with a crossover point or points in the midrange frequencies. I wonder why more speaker designers haven't tried this approach?

Yes sir, 
This is exactly my very same experience of my wide band, assisted with midwoofers/+ tweeter.

Magical and near perfection,,,

Oh sorry to step on the old cliche
**No speaker is perfect**
So sorry,, let me rephrase the Iconic **most Holy* Dogma , nO speaker is perfection..
OK
How s this
*Near perfect as I ever wanta  speaker to sound**. There, not perfectperfect, But as near as I ever hoped.

It's a complex subject, but the point remains that wide band drivers with all the requisite capacities are exceedingly rare, and pretty well all have shortcomings of some sort..

~~~~~~~~~~~~
Agree there are the good wide bands and then there are the poor wide bands. 
Voxativ AC1A rates in the very poor category.

Some DavidLouis are nothing great, while a few of DaviidLouis,, IMHO are the best in the world. 
2nd to none.
These DL's are relatively new and not well known.
I just made the discovery.
My only interest in wide bands are the davidLouis comming from some china lab. 
Germany could take lessons from this chinese speaker tech geek.

seikosha210 posts05-06-2018 1:57pmI thought the exact same thing after I converted to single/wideband driver designs  I think the main reason is the ragged frequency response and the marketing issues this introduces.  Buyers and manufacturers want to be able to justify their products/purchases with impressive specs.  I’m past that, sound first, measurements second.
~~~~~~~~~~~~~~~~~~~
Absoluetly
 The only few specs that intere4st me is
Most important
1)  db sensitivity TRUE REAL sens, not fake.
2)  magnet weign, magnet type,. I prefer Neodymium
3)  Cone material, (Sorry german labs, your papyrus paper thin cone just won't do, no bass) I prefer mix paper and wood.

All other specs/charts, graphs are just numbers,,w hich has nothing whatsoever to do with how  a  wide band ACTUALLY sounds in real time

seanheis1460 posts05-06-2018 2:14pmNot many folks realize this, but you can stick a $50 wide band driver on a 48x60 inch piece of plywood (with just a hole cut for the driver) and get mind blowing good sound from a current source amp...and if you use the right driver you can get bass below 50hz that gives a smoother room response than a sealed sub.
~~~~~~~~~~~~~~~~~
There is another forum where the topic is open baffel
I dont care for OB's.
I get more bass froma  wide band is a small cabinet, small port at bottom.

The DavidLouis 4 incher/mixed paper  in a  small cabinet, puts our rock solid bass down to 80hz. 
Thing ROCKS,,however midrage is a bit stressed, which is why i went with its big brother,, the 6.5.
has bass, but different,a  big less punch, but deeper/softer.
I havea  8 arriving,, I'm hoping to get your 50hz, has a  wood cone,,looks very promising,,Gonna run both 6.5 + 8 incher, like stacked Wide Banders.

cellcbern OP55 posts05-07-2018 7:36pmHere is a paragraph excerpted from Laurence Borden's July 2014 review of the earlier Bache 001 for Dagago. I think it gets to the heart of the augmented widebander advantage:


"In a typical 3-way speaker, the crossover point between the midrange and tweeter is typically between 1 and 2 kHz, which is smack-dab in the region to which our ear is most sensitive. No matter how well designed a crossover might be, the tweeter and midrange drivers invariably differ in their dispersion characteristics, transient response, and distortion characteristics. Making matters worse, the crossover often introduces phase shifts. Although these differences are often not recognized per se (except in especially poor implementations), they become apparent when they are absent, as they are in a speaker based on a wideband driver. As implemented in the Bache Audio speakers, the Tangband covers the range from about 100 Hz to about 10,000, or almost seven octaves. Not surprisingly, they are superbly coherent. As a result, music has a wholeness — or oneness, if you prefer — that makes it seem more lifelike. One has a sense of being more relaxed while listening, a trait I find very desirable in a speaker. Not surprisingly, instruments that span many octaves — like the piano — are especially well served, yet all instruments benefit".

~~~~~~~~~~~~~~~~~~~
The info in this article correlates exactly  how I am hearing the wide bander response in all forms of music,.
Simply magical.
When I had the Seas Thors over hauled with new tweets/new Mundorf crossovers,,, I was a bit disappointe,, So I ordereda   few cheapo wide abndsers and started experiementing,, Thought I liked what i heard,, One day I placed a  Thor on  one channel, a  wide bander on the  other.
WOW
What a  revelation,. 
Immediaetly I yanked out the new $700 Millennium tweets, listed then on Ebay at 60% off, sold in 2 hours, 
Took that cash and bought a  superior wide bander,, 
The rest is history.. 
My projects have been all 
Wide Banders...
I am near completion.
A wood cone 8 DavidLouis arrives  this week.
Gonna stack both the 6.5 paper mix DavidLouis  with the 8 Wood Cone DavidLouis..
All I can say is
Mr Wilson look out.... there's a  new kid on the block...and he aint playing...
