Hearing Is Believing This is an interesting concept which the article notes may find it's way into HT. I'm not sure about that, but the technology does hold some interesting possibilities. Especially with any kind of near-field monitoring use. The article doesn't mention exactly how broad the frequency response is, but I think this may improve over time. It says that the invention can't reproduce the lower-end frequencies, but I wonder if that problem could be corrected with a well-tuned subwoofer. In the future, the subwoofer may be the only conventional speaker in the entire system. It brings up an interesting concept, though: A home theater with several "sweet spots;" each one focused on a different listening position. If you aren't in any of the specific areas, the sound goes away, leaving the rest of the house in silence. Or perhaps this could be a secondary arrangement, with a "normal" speaker setup for most uses.
