Single driver vs traditional 3 way loudspeakers

Any two drivers design , add extra tweeter must use at least one capacitor ( first order crossover ) at least, If you connect  tweeter direct it will blow away instant 

HA Ha

@audiokinesis  Thanks very much, i  got the long way and spend  a lot of time . i  did not make a lot of sale , but all my customer is happy. i open show room  for public in Brooklyn NY, also my customers in Long Island and  PA,  

@david_ten , Did you feel something the sound becoume slightly thinner
especially when you listen cell, low octave of piano or mens vocal ?
Or not

@grinnell  you wrong  , look stereophile specification 
   
Description: Two-way reflex-loaded loudspeaker for use with stands 26-28" high (not included). Drive-units: 1" impregnated fabric-dome tweeter, 7" woven carbon-fiber cone woofer. Impedance: 8 ohms. Sensitivity: 92dB/W/m. Frequency response: 44Hz-20kHz, ±3dB. Crossover frequency: 3kHz.    (  that mean you got crossover )

can you compare Charney with Tektone or Volti ?

 Designing a single-driver speaker is very difficult since that driver needs to cover the entire frequency band. i  stating that one problem with such speakers is that they perform poorly at the frequency spectrum’s upper and lower ends.    My company Bacheaudio   further stated that he tried adding a tweeter to his early speaker models, but got poor top-end results. we  also tried pairing the speakers with subwoofers, but found that a suck out in the upper bass to middle-midrange region of about 100 to 500Hz caused voices and instruments such as piano and cello to sound thin.

 

What  Bache audio  ultimately gravitated towards was the so-called “augmented wide-band” (AWB) speaker, which uses a single wide-band driver that covers a large portion of the audible frequency band accompanied by several of what he calls “helper” drivers, in this case a super tweeter and one or more woofers.  we  states that this hybrid design incorporates the best attributes of the one-way designs (exceptional dynamics and coherence) and their three-way counterparts (excellent frequency extension and dispersion characteristics and the ability to play loudly without distorting).

 

@limomangus 

see my prev post , paper wrapped around cone is still a paper

Thanks, very  interesting 

@kenjit  agree, how whizzer cone , just piece of paper can be compare with High quality tweeters , This is Woo do. Basically whizzes cone   drivers was used  in all analog Tube amps and Pro acoustic in Cinema
How they widely used in High End is magic 

 Very good ,  but for my experience and design, if you choose Single driver , the baffle need big size  https://forum.audiogon.com/discussions/wide-baffles-and-baffle-step?highlight=baffle  

@grinnell    Single driver crossover less design assuming no any  coil or capacitor involve, for 2 way like monitor DE Capo   the woofer may connect direct with no crossover network, but tweeter using capacitor that meaning first order crossover design involve  for tweeter only, They must using capacitor to avoid blow up tweeter .   Most of 2 way design using one High quality coil ( Inductor   ) for woofer also to  get off cone break 
frequency. If De Capo dont using any coil i dont know is good or no .
@auxinput   Agree for 100 % , in all my design i am simply remove whizzer cones 

"That is why any 'full range' driver is nicely supplemented by a tweeter,"


Exactly. Any full range driver ( use pretty big cone) need to help in HF.
usually all driver Co , say ---16-20Khz, but don't say what is level down
6db or more, Actually  start to go down from  8Khz .Whizzer cone is stupid idea, yes is adding high , but is not control. sometimes is make sound too bright 

Not any tweeter ,  we are using top of the line supertweeter  Fostex EX line . . we try to use DavidLois, vox, clone.order one pair ebay and Compare to 2145 TB,  decide to stay TB, and DL sold.  for my expirence measuring and listening , whizzer cone little differences, diff resonance depending of size and configuration , but using same idea, on resonance fr, got peak and go down rapidly to 10hz, definitely much more worse than tweeter, but some folks like it and enjoining ,   

Ok , we have different point of view on whizzer ,  for me whizzer cone is parasitic element came to stereo hi end from cinema-pro era, where was used huge cone driver with whizzer cone loaded Tube, The freg 8-10KHz
good enough fo quality sound in cinema. There is only one benefit for Whizzer ( mechanical tweeter)  no crossover , no capacitor , no any phase distortion,  Many audiophile like it ( inc you liked it) , so good for you,   

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.

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 ,    

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

Correct, i can say most of full range drivers got dip in lower mid ----upper base 150-300 Hz that causes tiny sound .

@mozartfan Dont look on chart too much, get measur Microphone or
much more simple advice, if you believe you davidlouis or any one single driver got good performance . take equalizer and while playing raise 200-300 hz up
and you will see  big difference

EQ just for test, must me 10-12 grade at least, i used digital , build in some program so you have to be able boost 200-300 Hz. i am sure you will be surprise, actually it does not matter for customer or for yourself, try and let us know

Price ?  Free, Online downloaded, sorry  i did not remember, which one

Some things got different name , but actually is the same , sausage, and kielbasa, If manufactories say -no crossover  is mean nothing between drivers and amplifiers,    no capacitors , no inductions . If they use capacitors , does not matter how is say--- High pass or Low pass is mean -----CROSSSSSover

Hello @alexberger , also is very hard to add super tweeter to whizzer cone wide band drives, ih this case we have two tweeters - one mechanical -whizzer and other one electrical, we have to say by by one’
i say by by to whizzer tweeter and cut it down, I know some guys do it same and say whizzerectomia , may be wrong spelling

I use 0,33 mkf capacitor ,  can say  HP filter or 1 st order crossover for tweeter  Fostex Ft-96  EX-2 pared with 4 " TB-  1320 in my current models Lexington and Urban, did a lot experiment with 3 and 4 orders. Stopped on simple
