Here's a read for you. Mentioned are the Hafler system, and a Polk system. Looking at the list of applicants for patents, one sees a lot of familiar names. Also interesting to note the first app goes back to 1934.

    So who owns the SDA patent now? Polk Audio, or Matt Polk?:confused:
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    The inventor owns the patent, although that "property" can be sold.

    I stumbled across this site while looking for info on "MARS", or, McShane Ambience Recovery System.

    Charlie McShane was the guy that did the AR-3a. It's a long freakin' story, but I met him while exploring the mountains of Utah, and while he was there working for/with Jim Fosgate. Anyhow, that blew the **** out of me cause it was around the early 90's, the AR-3a was the first real speaker I ever heard back in 1968, and I STILL didn't have a pair, but here I was bullshitting with the guy that did them for AR! Up in the mountains of Utah!

    Anyhow, McShane marketed a line of speakers not too many years back (after the Utah encounter) that featured "MARS" and I never saw a pair, or read anything about them being reviewed by anybody.

    McShane IS on the patent list, right around the time of his MARS project.
