Speaker Tech

Speaker technology has changed very little since 1924, when Chester W. Rice and Edward Washburn Kellogg, two General Electric researchers, patented the modern moving coil, direct radiator loudspeaker, which became the prominent design for all speakers, until now.


Some say that since our ears don’t change over time, that there is really no need to change the nature of a “modern” speaker, which according to scientific tests, are able to output every frequency and tone that the human ear is able to hear. However, there is a fatal flaw in this understanding of the so called modern speaker. The ear is not what does the hearing, it’s the brain. The ear is only a mechanism that routes audible signals to the brain, and it’s the brain’s job to sort them out to give us the sensation of sound. This is what explains the effects of some hallucinogenic drugs that allow the user to experience color and shapes as sound. Of course we don’t recommend you running right out to your local drug dealer to experience this for yourself! What we need to understand is that “sound” is bigger than an audible force, rather it is a series of vibrations that are interpreted by the human as audible sound, movement, and pain. Really? Pain? If you don’t believe us, just Google “sonic weapon”.

To truly understand what a speaker should be, we truly need to understand what sound and hearing are. Without going into an in-depth and boring explanation, essentially what we need to focus on is that the brain is more important than the ear when it comes to “hearing”. Currently, all speakers being manufactured cater to the idea of sound in that they are targeting the “machine” of the ear. Creating truly revelational audio requires more than just controlling the audio wave spectrum. It’s about understanding what the brain will do with the information it’s getting from the ears, not the information itself. Do you ever wonder why when you listen to an audio system put together by a technical person (like a scientist or engineer), that is seems like it’s always missing something? Either it sounds too thin or too muffled, or something just isn’t right. It’s because more than likely your scientist was so obsessed with getting a perfectly flat system (which is pure and proper audio), that he used scientific gauges and tools (like an audio spectrometer or analyzer) to “tune” the system and the room to be perfectly suited to the human ear, not the human brain.

There is a huge gap between what our ear can technically hear, and what the listening experience is. Case in point; when the CD first came out, we were all impressed that our album collections could now fit onto a single shelf, instead of sprawling all over the floor in front of the hi-fi, like a giant music millipede. But then we noticed that for some reason, it seemed that something was missing. When we were fed up enough, we dug through the garage for the old turntable, and wah-lah, there was that sound we were missing. Why was this? After all, a CD can handle frequencies from 20hz to 22khz, which covers the human hearing range. However, other non-audible frequencies on the extreme low and high ends, are processed by the brain in terms of vibrations and harmonics, resulting in a sensation of “fuller” sound. So Mr. Scientist, what are you gonna do now? The answer was, make everyone buy a subwoofer, and to encourage automakers to put more treble speakers in cars, closer to the ears. You can see evidence of this in any new car touting its “18 speaker audio system”. And don’t forget the sub!

Now that we understand that hearing is not about the ear as much as it is about the brain, we can begin to understand that a speaker, is not as much about emitting sound as it is about emitting waves/frequencies, whether audible or not. Fortunately, digital audio has come a long way since the CD, and audio mixers of music and sound are using more of the frequency spectrum than ever before. That gives the common everyday ordinary speaker a lot more to contend with. More sound, and more vibrations. Those old paper cone speakers just can’t dance the way that today’s current sound demands. We literally don’t know what we’re missing because no other speaker design exists.

Enter SpeakerWrap. Let’s just say that SpeakerWrap is a combined effort between the quest to deliver audible sound, and the quest to allow the brain to “hear” everything the author, writer, director, producer, musician, etc. intended. Not only hear, but feel. Some call it psychoacoustics, we call it obvious. We’re not reproducing sound for robots here, we’re creating a listening experience for a person. The difference between the two philosophies is night and day, and that is the difference between SpeakerWrap, and our competitors. Find out for yourself with a SpeakerWrap demonstration near you.

Ordinary speakers make you listen, SpeakerWrap allows you to hear.
