Does "full range" really mean anything?

Speakers with response below 30 Hz can convey a lot more venue information, which is important to the music listening experience.

Winegasman, it's a lot cheaper to fudge the low end than high end. As one dealer told me, bass is related to cabinet size. Forget spec B.S. You are not going to get Quality, low distortion bass from a small speaker cabinet.
From my subjective experience, you don't get full range from any two-way regardless of what the measurements say. I think you simply need to move a lot of air for bass to have real impact. It may be measurable but that doesn't mean it's "there".
Second, again from my subjective experience, active speakers are way better at producing punchy, powerful bass. Just listen to Mackie's little 824 two-way. Way better than any passive two way I've ever heard.
I heard ATC active 100's with a claimed bass only in the mid 30's. Again, active bass drivers but a three way design in a good-sized cabinet. After hearing these I thought, WOW I have never heard bass like this. True 30 hz bass is, as William Shatner would say: "Big, real big".

There is a lot of music that has no real low frequency signal, and the high end, above 14KHz becomes less and less important as you go through life. There are other characteristics of a loudspeaker that remain important, and a "full range" speaker (meaning no crossover" can excel for these characteristics.

I endorse the idea of a secondary loudspeaker system , to be used instead of the primary one when the music and listening conditions are appropriate. A small full range speaker is a good choice for this.

It's supposed to mean the full spectrum of human hearing capability (20-20,000 Hz).

full range speakers is complete marketing and nothing else period!! Most (98%) of the best speakers in the world (cost no object) are designed to not be full range but to cover a lesser range with better sonics.

And exactly which part of your nether region did you pull that statistic from?
