Single driver vs traditional 3 way loudspeakers

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.

FR - Full Range (i.e. 1 driver to rule them all)

MTM - Mid/Twetter/Mid, kind of but not necessarily synonymous with a D'Appolito alignment.

They have narrow vertical dispersion, but also thanks to the dual drivers, less IM distortion, and if crossed to a good woofer, even less.

I wouldn't say they are the easiest to get right, I've seen some famous makers recently make questionable choices.  Hahahaha. :)

As you all know, the only reason I come to this site is to completely derail discussion threads, so here I go:

Don't forget the Woofer-assisted wide-band either!

It's kind of like a full-range, but with a woofer.  The main advantage is the lack of a crossover in the midrange/treble region, while still having all that full-body woofer goodness.

Of course, this is a great subject to recommend DIY experimentation.  Madisound, among others, has a number of affordable full-range (single driver) kits you can play with while you are stuck at home with the kids. :)
