Single driver vs traditional 3 way loudspeakers

8" sigma is   no good I , not for me, very bad freq response, if you see this got the pick about 10 db on  3.5Hkz , cone break , same f-n issue like TB 1808 and illuminate on TB 2145 ,  i guess the cone is too light , 2145 got  fiber on paper and does not this issue, and definitely requered super tweeter , fr response go down after 5 KHZ. No good for customers ,    

Last year, I spent 3 hours on each occasion - critical listening sessions to Charney and the Cube Audio Nenuohar. And I didn’t much like either. There was no intimacy or dynamic range to me. I much preferred multi driver speakers and acquired Harbeth 40.2’s over them. 
I suspect my ear- brain connection is simply too slow to pick up all the downsides commonly associated with multi drivers. 

Got you, i open this tread to find out all opinions,  we design all my bacheaudio  based on wide range with bass and high drivers help, like compromise between two, Single base Ls got a lot issues ,  but still  folks like it and buy.

**single base Ls..*  translate

Sure other than you and I, there really aren't more than a few others here on Agon  who are into (= hold the belief WBers represent the ultimate speaker design, 2nd to none, cultists, heretics, philistines) WBers as most practical, most hifi speaker design of all speaker designs.
Including ZU's *morphed WBer things*
Have no idea what's up with that speaker.
Nothing I like about the company.
Your lab is wayyy ahead of the curve.
As I mentioned the sky is the limit.
These WBers are the real deal. 
So yeah i can give you my imput/ideas.
Its just a  matter of time before your lab becomes a  big hit.
So if I were you i'd really get ideas going and make some plans to work on new designs. 
I plan to add the TBW31878 , this will give me  3 WBers in each channel, + the W18's, + a  tweeter.
I really got things rockin here.
I googled  alot to try to find if any one else has such a  design
So far no one.
I think my 3 WBer speaker is the only speaker with this concept.
I'd add it today if I could, but the  past yr WBer experiementation has busted the audio piggy bank,

Sorry , loudspeakers based on one driver, Single driver loudspeakers,
Good luck
