Why bolt a speaker onto a sub? Well, if you deploy five or more of them, your surround system's regular sub will have huge reinforcement, great coverage, no holes in bass response. That's what Procella does with products like the new P610. Thanks to shallow depth, it's not as bulky as it looks. Inside are a 10-inch sub driver at bottom with a 6.5-inch midrange and one-inch tweeter at top, the latter recessed deep into a waveguide. Price $3199 for the speaker half and $1499 for the sub half.

First seen as a concept piece at CES last January, the HMZ-T1 is now ready for prime time. This headmount 3D display includes two small, 720p OLED panels—one for each eye—in a futuristic-looking contraption that sits on your head with padded earphones on the sides. The interocular distance and earphones are both adjustable, as is the support structure that holds the device on your head. Because the two displays are completely isolated from each other, there is no crosstalk whatsoever. When fitted properly, most of the unit's weight is on the forehead, which is reasonably comfortable, but I don't know if that comfort will last through an entire movie.

The image is truly amazing, with exceptional 3D and super-deep blacks. However, moving your head around and seeing the "screen" move with you is very strange, especially when you can see the floor below the unit. Fortunately, light blockers can be installed to more completely isolate you from the real world.

After Belkin's first attempt at a wireless HDMI system several years ago—which never got off the ground—the company is trying again with its new ScreenCast AV4. The system uses the 5GHz radio band and consists of a transmitter, shown here in the lower right, and a receiver (upper left) that can be up to 100 feet away in the same room. The transmitter has four HDMI inputs, which are selected with the included remote, and it can pass full-resolution 1080p and 3D signals. Available this fall, the list price is $249.
