Single driver full range speakers

@tcutter - it is full range driver, low freq. can be extended by cabinet design, there are many fostex DIY solutions available. 

fostex has many drivers for 1 way speakers, price typ reflects how accurate it is: https://www.fostex.jp/en/speaker-unit/

I appreciate that 50Hz to 15KHz is quite extended, but I believe "full range" extends even more. I would not regard the LS3/5A with similar low end performance but a superior high end to be full range either. Perhaps we just define things differently.
 

No One Person has been able to hear in use most of the Single Driver Speaker Designs that are in use either from a Commercial or DIY Build background??

For an individual to suggest most Single Driver Speaker don't sound very good is a fantastical statement made without a solid foundation, as a result of their exposure having very very limited experiences.

At best most of the ones heard by an individual, especially an individual who expresses a negative content as their evaluation. Might have been exposed to an End Sound that to them did not sounded very good, if that is an experience had, then I am not to argue.

Any individual is limited in what is able to be experienced and only able to encounter what is a very very small proportion of the entirety of single driver speakers.
Which as a overall quantity, adds up to a minuscule amount of speakers that are actually available to have their End Sound heard and assessed. 

Where the evaluation by an individual of such a small amount of speakers is that all Speakers using Full Range Drivers are no good, is a statement that is extremely deficient in information.

I would strongly suggest such a statement is bordering on worthless.

@pindac 

I do not find any posts that state or even imply that full-range speakers do not sound good or are "no good". I do read a number of posts that detail their shortcomings, as all speakers have, and a few that question the appellation "full range".

" most of them don’t sound very good once the listener gets past the honeymoon phase "

As I stated, " Any individual is limited in what is able to be experienced and only able to encounter what is a very very small proportion of the entirety of single driver speakers. " 

As always my post was to pass on an improved information to somebody who may be looking in on the thread or discover the Thread at another time.

Can't be having such individuals being given information that is substantially askew with incorrect content.
