Otherwise known as Single Driver speakers or Wide band driver speakers
I call them "full range drivers" as that is the keyword that will find them for you when shopping for a driver. Shopping for a "wide band driver" will NOT get you suitable drivers for this purpose, only with a more limited bandwidth in comparison. Also, shopping for single drivers will also get you the coaxial drivers, which is another beast / genre altogether.... so while we are not talking about 20Hz-20kHz, we are referring to the entire region you hear reproduced being provided by a single driver....
Before you start demanding for wider bandwidth, you MUST hear these speakers, as it's quite possible that the "limited" frequency response on both ends does not tell the meat of the story: that the wide band centered on midrange is actually much cleaner and has better integrity than with multi-driver solutions.

Hello Janos,
Thank you so much for giving your insights on these drivers, and the LePetit!
Although I don't comment much anymore (I watch on my TV instead of the phone,) I watch ALL of your awesome videos.
I have used the FE126 for about 8 years, and am always delighted to listen to music through it. I noticed the Fostex 108-SS HP on the Madisound website, and was wondering if you had time to share your thoughts on that driver. I have tried the 108 Sigma (and some other 4-5" FR drivers) and thought that it was just "OK" compared to the FE126. Would this, or any of the Markaudio drivers like the MAOP or Alpair 7 be an upgrade for me? They all seem to be of lower efficiency, but perhaps more balanced. I am still using my DC 45 amp, and can use 2A3s in it now as well.
Best Regards, Cory
