A full range speaker?

Read what it says over a few times and it will make sense.. We want it, in your head, not over your head. :-)

~~~~~~~~~~~~~~
Yes I looked over the Tannoy's. Interesting,, Seas also has a  ~~Co-axil__.
Interesting if you read the descript, Seas says they designed this ~~concentric~~  with the highest regards for super high fidelity.
Again, interesting. 
But note, Seas says  bass is 150hz, more as a  midrange-tweet.

I am sure the Seas along with a  Seas W22 Graphene would be a  nice speaker, caveat $$$$$$$$./
So I went with the 
DavidLouis wide band @ 91 ~~TRUE!!!~ sens and bass does in fact hit the 60hz, if not 50hz before roll off. 
Mids/vocals are accurate and nothing harsh nor  showing signs of stress at moderate db levels on gain.
Highs are there, rolling off, maybe like 13k/14kish. 
= highs are sweet and satisfactory.
So for $450 its right in my budget, vs the layout for the Tannoys  which I may have some issues with either in the bass/, mids or highs.
I have no issues whatsoever in the DL 6.5
This lil DL 6.5 is the speaker to beat out ina  shootout  IMHO/2 cents worth.

Here's another demo of the DL6.5 in action,.
Its everything i hoped for in a  speaker. My experiements , though costly, have paid off.

 The DavidLouis has no other YT  uploads except on my channel. I will be making a  long series of vids over the next weeks showing just what this speaker is capable.

Dis the above DL video, This is DL part 2. I am telling you, this lil wide band delivers rich detailed  nass/mids/highs. 
I would not trade this DL6.5 for any speaker on the market.
Not even the Wilson top line.

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
