Mr Edwards (I think that's your name):
I find the issue you raise, rather inadvertently, a very interesting one. As a matter of habit, I come across a lot of people, a bit like yourself, who know absolutely nothing about audio, and in fact are deaf (or 'tone deaf', for the present purpose, it makes no difference), but propose to make audiophile products based on what they have read here and there on forums or Wikipedia. May I ask you, if you are incapable of discriminating results from an audio perspective, why you think that suddenly you might be competent to make or develop a product intended for this particular field? Is this because, quite correctly, you have worked out that this is a hobby dominated by irrationally superstitious and self-deluded individuals, who are a perfect clientele for all sorts of premium products of doubtful efficacy?
After all, you no doubt would agree that a structural engineer who had no understanding of the maths involved in calculations of loads would be ill qualified to design the foundation, wall and roof structure of a house. You would think that someone who is blind would not offer himself for a career as an airline pilot no matter what level of competence he might have in other related fields. But somehow the fact of being tone deaf does not stop you from pursuing an area which requires an ability to discriminate in terms of sonic results. Well, I am baffled!
In addition to being tone deaf, you have no training or clear understanding of room acoustics, and the interface between loudspeakers (not to mention the different designs with their own set of problems) and their surroundings but you feel that with some research here and there you can come up with a commercial product. Well, I wish you good luck; in these economically uncertain times, we all need to make a living, but I must say that your approach and the domination of audio generally by individuals of your ilk is what makes this the most difficult hobby to pursue. Please let me know the name of your company and products, so I make sure I label it alongside the many others that I would avoid like the plague.
Again, please do not take any of this personally, it is just an interesting topic and your rather, shall we say, cynical opening gambit made it difficult for the rare contributor that I am to resist a comment about audio, which your initial post truly wasn't after all. You only want to know whether there is money to be made in offering walls with curved corners. By the way, have you ever wondered why our heads have a slightly ovoid shape with no square corners? And why our ears are the shape they are? Maybe the answer is lurking in these considerations.
