way of directing our perception? Loudspeakers (and for that matter, the entire audio system) are a priori, and for better or worse, a functional part of a system which creates the experience of electrically powered sound for human perception. Listening to music is unquestionably an art - the drama of art is always best brought into relief using many different perspectives, and we always benefit from having our perspectives challenged and changed. It widens our awareness. So if you will permit me to adjust your question, I would like to rephrase it as: do Podium loudspeakers provide an effective experience of sound which is totally different, perhaps challenging to some, but still completely legitimate for human experience?
Of course, I am also delighted that the Podiums are also strong enough to demand that previous and more conventional technologies be re-considered, in light of the performance of the Podiums. For example, the Podium .5 has an efficiency which is conservatively measured at 93 dB. It is completely stable, will not be affected by humidity or dust, will not degrade over time, has excellent power-handling, very high efficiency (so it can operate with a 5W amplifier), needs no external power, has a tremendous dynamic range, and truly fills an acoustic space with sound. I don't know of any other flat loudspeaker that can make all of those claims, and few conventional loudspeakers.

What can you say about the technology you improved? (I know itīs patented, but listener wants to know something more...)
Patents are actually not important, except to indicate the significance of the technology in terms of originality. What is more important is whether the patented technology is of any use. Many individuals file patents on ideas or even finished prototypes without knowing whether there is any need or desire for the technology they patent. Then they try to sell it and to their great disappointment, discover that in the world market-place, there is little or no real use for their invention. The patent offices around the world are full of technologies like that and it might be seen as sad, except for the simple fact that if we did not have the dreamers in our world, who actually tried to make the human condition better than it is, we would all still be

living in caves. I was fortunate to begin with the question: "how can I build a digital piano that will sound like a real acoustic instrument?" The need is simple: many professional pianists like myself would love to own one of the top concert grand pianos, but we generally cannot afford one, nor would the neighbors appreciate it, but all digital pianos are frankly terrible.
What I finally achieved, after many years, was to build a digital piano which did indeed sound as good as a top concert instrument. That was done using the first and main technology I have patented, now being licensed under the "Enlayered" brand name. But to enable the Enlayered technology to be commercialized, one needs a good, incoherent sound source, and none existed. So the method I used to develop a good incoherent sound source was exactly the same I used to discover the original Layered Sound technology in the first place: ie to throw away all preconceived ideas, and to let myself be guided entirely by my ears. Thus, I was not interested in doing iterations of prediction and test, using mathematics and analysis. Rather, I went directly to the final goal, and first kept building models until I found a product that sounded good - then I analyzed and measured it until I understood what I had done.
The Podium loudspeakers are relatively simple because I always seek simplicity. I try to work with the nature of materials, rather than to force them into doing things that are not natural - I try to let materials and structures do what they do best and naturally, merely balancing them a little, so their behavior ends up guided and disciplined, rather than crushed or tied down. The P.5 is an excellent example - it has no cross-over, no electronics at all, just the drive units, and the mechanical tuning I call "Sound-Bridges" which allows me to bring the entire system into balance. Even the beautiful Seal filters inserted into the backs of the loudspeakers are elegant in their simplicity and effectiveness, because they work with the nature of the loudspeaker, with the acoustic environment, and most importantly, with the desire of the listener who uses them however they wish.

How many years, using your panels two hours a day, do you think they can guarantee music?
Assuming the loudspeakers are not physically abused, tests indicate they simply will not
