So I'm guessing this is similar to SDA but in a passive box that you can add to any stereo. Does anyone know anything about this? Will this be a real product that we can buy sometime in the future?

    They indicate the speakers should ideally be 50 cm or 20 inches apart. Hmmm.....

    They talk about a computer and filters, so it would be an active system. SDA is passive.

    I've been following this for a while as it's pretty interesting. They released a product a while ago, but it seems a bit out of reach financially.

    They used to have some demo tracks formatted for mac computers (for their speaker spacing) and something for a portable speaker also. I'll stick with ambiophonics and Polk SDA for now until some of this tech becomes more accessible.

    Eliminates cross talk and at that price, eliminates it from my possession.

    Damn, I wish I posted in that thread back in 2015. I would be an internet legend when this technology catches on. :'(

    2015... now it's... umm...what year?
    (I know, I did that arithmetic already tonight)

    With this context (thanks for bumping this old thread!), this story is starting to remind me of a high-tech company I once worked for -- we used to say (cynically, of course) that the company's motto was:
    Bringing you yesterday's technology tomorrow

    :#

    Now, implementation of this technology with a pair of, say L-200s, might be interesting. Not at $54k, though ;)

    My guess is that eventually the VCs funding this will sell it out to someone who'll put it in smartphones, and it'll be a soundbar style 'spatial enhancement'.

    Thread back from the dead! :#

    Remember BACCH?
    There's a field report of sorts @ AA. Since it references some old-school analog faves (Sonic Holography and... umm... SD... SD... SD-something, eh?) ;) I thought it might be of interest to those who don't amble past AA much any more. B)
