Single driver vs traditional 3 way loudspeakers

FR speakers certainly have their limitations. They have a very specific sound signature that may not be to everyones taste.


~~~~~~~~~~~~~~~~~~~
WEll if  we make the 20hz-40hz fq range a  limitation then yeah, WBers fall shot here. 
But again in my classical music, cellos lowest notes are in the low 60hz range. 
Jazz fans also, not much below say 30hz.
Less than 1% of the music is below 40hz
*Signature sound*.
I find xover types all suffer froma  *House Sound*
Bose, B&W's havea  distinct sound,,which we all tend to avoid.
My Seas Thors were extremely neutral, = no house sound, Perfectly natural in voicing. 
But at 87db, = wet blanket sound.
All WBers will differ in sound.
The Tang BandW82145 and the DavidLouis VX8, sounded nearly identical.
I shiped the TB2145 back, although it is a winner, But I just now realized with that aluminum phase plug, it may very well have beamed highs.
The DLVX8 with a  unique phase plug + whizzer has very little beam effect.
**Not to everyones taste**
Fact it, the hard  truth is
 Audiogon is a  xover traditional 3 way discussion board.
Most of the members have yet to hear any WBer in action,. 
Perhaps the old Lowthers, Fostex's back 20 years ago,
Those don't count today.
WBers have come  a  longggggg way since those 2 early models.

has that spiked center phase pulg which eliminates beaming.

This conclusion is false. What the phase plug does is prevent cancellation from one side of the cone to the other, so the highs generated can actually be heard. It does not prevent beaming at all; that is simply a thing if you have 'full range' drivers without a tweeter.

Well I may have ead something in the descript about the odd spiked phase plug as helping eleiminate some beaming effect.
I vaguely recall now the Tang Band 2145 8 may have had beaming issues. 
I only had it testeda  few hours then boxed it up and shipped it back
I was unaware of this beaming effect at that time, 3 Months ago,
Its still a very accurate midrange speaker with great bass (considering it is a wide band) and has IMHO excellent highs.
I say IMHO , due to this prejudice that WBers lack the  ultra highs.
If you want ultra highs witha  WBer set up grab any hifi tweet and there you go you got it.
Lack of 20-40hz bass and ,,say 12K++ highs really is not a  issue with me as far as WBers are concerned. 
The mids in my WBer 2 way is a  voicing that i have not heard in any xover style speaker.
My guess is over the comming decades more folks will want to know  more about these WBer *things*.
Looked over the DavidLouis for about 3 years before I made purchase.
After 6 or 7 trial N error I found what I was looking for.

It doesn't. It allows you to hear highs that you would not otherwise.


That is why any 'full range' driver is nicely supplemented by a tweeter, which might operate at only 10KHz and above. I've had them work nicely by having the tweeters firing to the rear so that if you are a bit off-axis, the tonal balance is still correct. When on-axis, if the speaker is far enough from the rear wall, the rear-firing tweeters will help the speaker play a more distinct image.

"That is why any 'full range' driver is nicely supplemented by a tweeter,"


Exactly. Any full range driver ( use pretty big cone) need to help in HF.
usually all driver Co , say ---16-20Khz, but don't say what is level down
6db or more, Actually  start to go down from  8Khz .Whizzer cone is stupid idea, yes is adding high , but is not control. sometimes is make sound too bright 

Arnold explain different in speaker using metaphor..
