A full range speaker?

Keep in mind the 6550's have more than ~~~2k~~ hours,,
all the sheen is rubed off. Still in all, this lil wide band delivers stunning highs. Exteremely accurate, with no coloration , zero fatigue = 
SUCCESS!!!!
Did not come cheap. 
I am the only YTer showing off the DavidLouis.

Its just that none, zero , of the commercial speakers interest me.
So that is why I had to design my own speaker, w/o any advice, suggestions, ideas from my tech geek nor anyone here on audiogon.
I had to make my own design, nilly willy, for the good or the bad.
Tried this, that, then swaped out that, for this, and so on.
Til finally i have pretty much my Final Speaker til death. 
You could not even give me a  speaker to replace my own design. 
You may not like it, but thing is , its my music, my ears, and this speaker is as close to my perfect ideal of how a speaker should voice.
Again, you might say ***THAT!!**

And I will respond, Its as close to my hopes of speaker nirvana, more than I could ever expect.
Each person has to come to his own ideas/experiences of how he wishes his ideal speaker to voice.
I have plans to add a  DL8, the white cone wide band
Will bea  shootout twix the 
DL 6.5 Neodymium
vs
DL 8/Ferrite magnet weighing in at a  blsitering 8 lbs!!!!!!!!!, Woden cone
One heck of a  shootout.
One or the other will be champ of wide bands.
My guess is I'll like things about both and so keep both. Swap out, depends on the music selection. 
Sort of adding spice and variety.

So like yeah, my speaker is all original, my ideas, no one elses.

William53b, in thinking about it I would to re-define my answer to reflect what I really believe. The full range that needs to be reproduced to create the "absolute sound" is 18 Hz to 20 kHz. However, no single speaker system should do this. Low bass requires a specific type of enclosure and location to perform well. Very low base also causes trouble with drivers that have to run up higher. Thus IMHO every system requires subwoofers. A main speaker should only be responsible for 40 Hz to 20 kHz at most on its own and 80 Hz to 20 kHz with subwoofers. So I would consider a loudspeaker that can do 40 Hz to 20 kHz to be full range. I have never heard a single driver do this successfully and my intuition says that you would be more likely to achieve satisfactory performance out of a well designed 2 way loudspeaker than any of these so called "full range" drivers 

@mijostyn

I agree. 40 Hz seems like a reasonable number for bass. And subs will always be needed to dig into the 20's. There are speakers that can go into the 20’s, but they are few and far between; and always rather large.

In a perfect world we would all be blessed with 14’x36’x12’ listening room, minimum, and the funds to fill that with our equipment. But until that day arrives I will have to be satisfied with trying to achieve that sound in a smaller room.

My friend is using the Lii Silver 10 on a four foot high baffle.....two feet wide....with four foot by one foot wings going straight back on the sides. He has measured 40hz flat in his room.....-5 at 30hz. The Silver 10 has a 28hz resonance. He added an ESS AMT on top using a copper foil cap above 10K......simply incredible sound. 98db efficiency. He soldered his speaker wires directly to the voice coil wires.....(he removed the binding posts on the speaker). This gives way better sound than going through a binding post.

Now he is going to add 2 15 inch woofers to each side.....he will bi-amp using a solid state amp and electronic xover for the woofs......and leave the 10 inch running full range or roll it off by using a smaller value of coupling cap in his tube amp. If the smaller value cap is a better cap then you have even better sound. By limiting the full range to above 100hz you will lower its distortion and increase its dynamic range. But, he has been listening to the 10 by itself for months and months now and is still Gobsmacked! The Lii drivers need at least 200 hours of hard playing to really loosen up. He has another system on the other side of the house and he can blast all day a new driver.
