[QUOTE="John Roberts, post: 47922, member: 126"] Re: Tell us what you see in your crystal ball.... I kind of see speakers being with us for some time, in an many places pretty much as is, while at the cutting edge they will still be driven by technology and perhaps invention. The laws of physics will not bend or be bent but that still leaves a lot of room for improvement. For example in a live show, a lot of sound energy still goes elsewhere and is wasted, or in the case of large outdoor concerts is a nuisance that must be mitigated. So I can imagine some form of focussed, perhaps cross modulated sound that mainly occurs near each listener... It seems there should be some way to design a club dance floor system so the sound from multiple sources combine on the dance floor but cancel elsewhere (while I'm not smart enough to tell you exactly how. ) Speaker technology may intersect with amplifier technology... another hair brained idea is to combine electrostatic loudspeakers capacitive load, with a PWM class D amplifier to eliminate all kinds of resistive losses,,, While electrostatic radiators are bipolar so that opens another can of worms, maybe some very clever horn guru can solve. :-) The future will be better and different, if we can just get past Dec 2012.. :-).. otherwise lots of work to finish before then.
