Any one heard of "invisible" speakers?

Hey Allen, checked out their website, i like the idea of the screen goo!
Not sure of pricing though.....

Hey Matt / Rod, what is your feedback on these products?

Personally I have no experience with this product so it would be unfair to comment however a good set of in-wall speakers would possible acheive a better sound being a more direct image to the listener as opposed to a harmonic field...

Regarding screens, and Screen Goo, also remember that having a black border around your screen is very effective at making sure you have a sharp defined edge to the image you view.

Also, by absorbing any little bits of "light smudge" (to coin a term) at the edges, or slight distortion or any other natural/normal artifacts created by a projector's lens, the angle of projection, etc., it gives you nice straight and parallel borders, guaranteed.

Rather than attempting to achieve this with a material you have to paint on yourself, after you've properly prepared the surface, I believe it a lot simpler to hang a fixed screen, and your chances of a perfect result go way up.

Also, if you consider how many hours would be involved in all of the above, you'll most likely find hanging a fixed screen the cheaper option too.

Now, invisible speakers. These are a great option where hiding the speakers is actually more important than the quality of the sound they produce. The technology used to be able to produce sound from a diaphragm that is essentially plastered into your wall has limits on how well/easily it actually procuces many/all of the frequencies you'd normally hear from a traditional type of speaker.

It is a lot easier to get a lot better sound from many much cheaper options.
