These tall guys that you are seeing here are part of the SC-ZT2, a “fully wireless home theater audio system designed specifically for Full HD 3D”.
Those long thin speakers have 7.1 channel sound, and they are completely wireless. They also have a “down-fire sturcture to use the floor as an acoustical reflector to produce dynamic bass sounds that are extremely robust for the size of the speakers”. The woofers on the speaker stands allow the user to have rich bass sounds on all sides.
The slim pole speakers and wireless receivers cost about $999.95.
