PS Audio has been working on a new speaker system that Arnie Nudell was helping Paul design. Unfortunately, Arnie recently passed away, so Paul is now on his own, although he has an excellent team to support his efforts, so the future of the project seems bright. Here is what he is thinking.
Before Infinity Speaker founder Arnie Nudell’s unfortunate passing, he and I were working on a new concept in loudspeakers, one based on the idea that it just might be possible to get closer to live orchestral sound levels than we have in the past.
A full orchestra can hit peak levels as high as 120dB. That exceeds the point of hearing damage, which of course was never our intent. And it is not hearing damage we get when in row one of an orchestra because peaks of this magnitude are both brief and rare. Arnie and I had become convinced this was the one quality still missing in speakers.
A few horn-type speakers can manage these extremes but none I know of without colorations (maybe the giant Magicos with their multiple horns? and extremely high price). Might it be possible to achieve these peak extremes without distortion, coloration, mega-amplifiers and bankruptcy court?
That is our challenge. Before his passing, he had made some good progress in a prototype he referred to as the IRS Killer. And it was. What we lacked to complete the design was a midrange driver of a very special kind. And that is now being worked on. It may yet be possible to complete the dream.
If you want to see what Arnie’s last prototype speaker system looks like, you can watch this video here. The midrange driver in this amazing reference design is a Bohlender Graebener creation no longer available, but that’s ok because it was the prototype’s’ one shortcoming.
