What are the specs of a full range speaker?

If low frequencies that serve to merely shake the wall add to one's experience listening to music, then why is it unreasonable to accept that high, inaudible frequencies add to the experience as well? The fact that humans can not hear frequencies above a certain frequency does not mean humans do not experience these frequencies in other ways. Does it?

I don't believe there is a formal definition of "full range speaker." As such, it pretty much means whatever the person using it wants it to mean.

At the least demanding end of the spectrum it could simply refer to any speaker system that is designed to be used by itself (i.e., not specifically made to be used with a subwoofer, etc.) Such a definition would include speakers with limited bass below 50 or 60 Hz.

At the far end, one can insist that a "full range" system needs to solidly go down to 30 Hz or below.

A similar argument can be made at the high end. As such, I consider the term fairly meaningless.

Ultra-low frequencies have the power to shake the walls, and physically
pressurize the room. It adds to the visceral experience of say, a really big
diameter pipe.

High frequencies do none of this. Their reported presence in an audio system
just feeds into psychosomatic twitching of true believer's brain.

How do you know this, Vince? Does the absence of a readily discernible physical phenomenon like shaking walls prove the non-effect of high frequencies on human experience?

You don't believe that human inner ears or human sinus cavities somehow process high frequencies...even as pressure differences? I believe they do.

Perhaps our friends Guidocorona or 84audio might be able to share some insight.

Maybe it's because I grew up attending a Catholic cathedral on Sundays. The organ play made it all worthwhile. I loved both the huge bass pipes to the ethereal strings.

Away from church, for twisted fun, I tortured the neighbors Shitsuitsu with a dog whistle. It was cruel, but I did learn dogs hear more than we do.

I once read the reason we hear between 20 and 20k, is because that encompasses all that is relevant to our survival. I'm sure that explanation doesn't wash with birds and dogs.

I'm one of those extremes that hears way high and soft. I don't know how many times I hear bright and grainy, when other listeners just hear highs. That leaves me agreeing with the dog, hearing UHF is not all that it's cracked up to be.

All I know is most systems are truly deficient in the 20-20k range, I don't know why anyone would want to perfect what they can't hear before they get what they can hear right.

Maybe it's because most people have trouble hearing above 14Kz they don't hear the deficiencies that their systems scream out between 14Kz and 20Kz.
