I doubt Dunlavy or anybody could possibly patent the idea. As others have noted AR has been using the idea since the 70's as had the BBC on the dimunitive little monitor that is the fave of so many; the LS3/5a... Also down under in Australia, Mr Dunlavy's former brainchild "Duntech" still uses the technique as do two other speaker manufacturers founded by former employees/associates of his, called "VAF" and "Sonique". If one were to dig around a bit more into the past as well as the present, I am sure one could find many other examples. That being the case I would say that it is in the public domain, therefore it is common knowledge and hence unpatentable...
Cheers.
