Single driver vs traditional 3 way loudspeakers

Back in the sixties and possibly into the mid seventies, JBL and Stephens-Trusonic produced what they called extended range or full range drivers.  Both used an aluminum dust cap for the mids and some of the lower highs.  For optimum performance, they were designed to mate with a tweeter, but on their own they still sounded very good.  No x-overs, not even a capacitor.  I believe there were 8,12,and 15 inch versions.  They come up on E-bay occasionally, but the aluminum dust caps are often dented.  I once had a pair of the Stephens 8 inch variant, and it was a very well made speaker.

" 

I have neither affiliation nor experience with Bache loudspeakers, but imo they are making excellent design choices.

@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,  

Hey @robn68
I believe that the Tannoy’s are not what we normally call full-range. They are coaxial. That is, they have 2 different voice coils in the same housing.

Different beasts, but lots of fans too.
A full-range speaker has only 1 voice coil, and no caps but some of the modern versions I see have mechanical crossovers and do have a separate tweeter dome.

Of course, I don't claim to know all things Tannoy, so I very much could be mistaken.

Best,

Just go hear s field cool design.  Then you'll be hooked. Happy listening
