A full range speaker?

@myjostyn

I am not looking for a solution, I can build bass horns that go down to 20 hz, and will shake my family room off of my house. How to get there is not the question, it is: 

What do you consider full range as a definition of a speaker catagory?

Because it is term that is used without any definition of what the term means. As far as I can see it's just a marketing term.

 I'd just like to find out what people consider that to be, so we can establish some sort of credible definition.

Geez, a lot of academic mumbo jumbo in this thread.  I have spent countless hours listening to full sized speakers with a -3db point between 22 Hz and 40 Hz.  Without question, the lower extension speakers have dramatically out performed over enough of my listening list that it is important.   Of course, sometimes 40 Hz is all you need, but there is plenty of music that plums the lower depth.  I have had Revel Salons, Thiel CS5s and CS7.2s in my listening room at the same time to compare along with less bass proficient speakers to compare.  It makes a significant difference.

Yes.   Suppose I framed it differently. 

Have you ever had bookshelf or stand mount speakers that you consider full range?

If you spend enough, of course you can buy full range speakers. But some decent ones can be had for under $3k

The term full range speakers is not the same as full range drivers, which is a separate category. I failed to make that clear in the beginning.

One definition from the web, of which there are many:

"The term “Full-Range” connotes the speaker that covers the entire range of the human voice. Most full-range speakers have a low frequency of around 60-70 Hz. Larger units with 15” drivers will reach low frequencies, while those of 10” LF drivers or less will roll off closer to 100 Hz."

Here is one example of a dictionary of audiophile terms, I’ll look for others.

William53, I think the definition is rather arbitrary. What is important is how speakers perform in reality in a normal room at normal distances. You can not rely on specs particularly when it comes down to low frequencies. There are painfully few "full range" speakers that make it down to 20 Hz gracefully particularly if you try to run room control. Read the article I just posted in this section. Low bass is a problem that is best handled in isolation. IMHO as moon-audio defines it there is no such thing as a full range loudspeaker. Good performance certainly under 80 Hz requires entirely different parameters than the rest of the audio range particularly when it comes to positioning the drivers. You might want to use totally different types of amplification such as a tube amp above and a SS bruiser below. Not that it isn't impossible but I have never heard a "full range" speaker produce adequate bass. 

Check out the upright bass in the article I posted. I never knew they made one like that! It is tuned to A0 which is 27.5 Hz.
