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?

 Speakers designers which try to use wideband drivers usually get some
mistakes .  First- to reduce distortion they shoud be works with
woofer with crosspoint about 500-700hz, integration with active bass
module become problematic and get issue ,  Active bass get crosspoint
up to 150-200 hz, and wideband driver get poor performance (buffel
step  ), Sound become is thin.  To integrate with tweeter  we  cut whizzer
cone ,I try to illuminate all this problem in my speakers line

The short history to design my speakers based on wide( full range )
First step-------------One driver no crossover
Second step- Bache audio-001 remove whizzer core ( i realize after measurement and listening is impossible to made flat response just to add supertweeter and leave whizzer is on) and add active Sub, crossing wideband with 100 HZ crosspoint
Third step-- I realize that wideband get poor ability to work midbass region 100-500 HZ ( baffle step) , Some Disigner to avoid this made very wide baffle (voxativ) I dont understand the ZU lover folks. The sound ( especially male vocal, lowest piano and
punch sound thinner than real , http://bacheaudio.com/bache-audio-00...tereotimes-com 
We made Bache audio-002 to add separate midbass driver with active build in amps . But for all another speakers based on wideband with no built in amps, we have to add woofer with crosspoint 500-700 HZ ( Metro-001, Tribeca-001 etc)

Conclusion-- Wideband driver get good ability just to work like midrange with extended freguancy response, and get choice to implement not regular dome tweeter , but supertweeter.
