Yes and no depending on how you define "wide range". Their 2'' compression drivers like the 2446 could be operated between 800 Hz - 20 kHz. But you will have to use top-octave compensation for this and personally I would use a supertweeter like the 2405 or 2402 with any 2'' driver.
And their (now obsolete) 2118 8'' midrange can be used between 80-7000 Hz although I would certainly not operate it that high.
Take a look at http://www.jblpro.com/pages/components/componts.htm for their line of (IMO awesome) drivers.
To be perfectly honest I can not see why anyone would want to use a large "full range" driver like a 12''. It would beam like mad and breakup distortion up high would be quite nasty. Transient response would be close to non-existent. Although I am by no means a single-driver fan I can see the beauty and simplicity of a single Fostex 4'' driver in a little box for a nice small system. But a single 12'' or 15''? No way!

Those JBL 12 " coax drivers are interesting. Wonder how they sound... The graphs don't look so great, but maybe they are just being more honest than most. (OK, they use a crossover so maybe they don't qualify as full range)- wonder what they cost
and how they sound vis vis the 8" Radians w/ horns at $300 ea.

I would put my money on the Radians- but it's a lot of money!!
The JBL's and 8" Radians are made for ceiling installation by pro sound installers. That's not too impressive, but what we usually hear with the feeble distorted muzac aren't using the higher quality drivers such as these. Radian makes 12" and 15" coax's too
Kuei recommends the best Seas coax drivers, but they are low efficiency - not based on pro gear so probably aren't best for low power....only about $130ea
Selenium makes 12 & 15" coax. PHL makes one with a dome tweeter but I heard that they aren't anything special. If pAudio or Beyma make some they might be well worth looking into- some of their horn drivers are supposed to be quite good. The trouble with pro gear is that there are so many manufacturers.........

Continuing the quest for a full range driver...
I have got rather excited about trying Bert Doppenberg's TQWP speakers using 2x 4-inch drivers:
http://pmillett.addr.com/tqwp.htm
I am thinking of using Fostex FE103E or 107E for the front drivers.
Two questions:
a) Their specifications are *almost* identical, but is there an advantage of one over the other in this design?
b) Can anyone suggest a 4" suitable bass driver for the rear unit? Or perhaps even better, what specifications should I be looking at to select one for myself?
Cheers!
As an afterthought, I believe there is a new Tangband 4" driver on the market. Can anyone comment on their experience with it?

Check this thread for good info on 4" Tangbands.

I'm trying hard to be modest but you may want to read this thread before committing to the BD pipes.

You can try asking over at Full Range Driver or substitute the Fostex FE-103E (which usually costs more unfortunately). I understand that Radio Shack of Canada is supposed to be stocking the 40-1197.
