Brand new Mirage Nanoset 5.1 system (five satellite speakers and a subwoofer). I originally bought for our living room and then my wife decided we should put in ceiling mounted speakers. Personally we should have installed these. Selling for less than half of original price, these are brand new in the factory sealed box with all manuals and paperwork.
Design and features - As per CNET:
The Nanosat 5.1 system comes with five satellite speakers and a subwoofer. The system doesn't include a dedicated center channel speaker; instead you get five identical satellites, which produce a better surround experience than a system with dedicated front, center, and surround speakers. Each Nanosat speaker is 5.8 inches tall and weighs 2.9 pounds.
Conventional box speakers have drivers mounted on their front baffles and project sound forward. The Nanosat 2.75-inch titanium/ polypropylene mid-bass driver and 0.75-inch pure titanium hybrid dome tweeter are mounted on the speaker's top-angled baffle. Top mounting isn't the only factor responsible for the MX's omnidirectional dispersion, as the speakers feature an Omniguide module, which has two deflectors itself. One tiny curved deflector is positioned over the tweeter, and the other is mounted atop the midbass driver's deflector. The deflectors project sound directly toward the listener, all while creating a 360-degree radiation pattern that reflects sound off your room's walls, ceilings, and other surfaces.
The Nanosat speaker's dome-shape perforated metal grille is covered in black cloth. Instead of pins or clips, the grille is magnetically attached to the speaker, which lets it easily snap into place when reattached.
The Mirage S8 subwoofer has a down-firing 8-inch woofer and built-in 75-watt (300-watt peak) amplifier. The medium-density fiberboard cabinet is rather plain, but the smoothly rounded edges and satin black-painted finish are a nice touch. Connectivity is limited to just stereo line-level RCA inputs and stereo spring-clip speaker-level connectors.
The subwoofer is 11.7 inches high by 13.5 inches wide by 13.5 inches deep, and weighs 20.1 pounds.
Performance
With the room lights turned off, the system's five satellites literally disappear as sources of sound. With conventional box speakers, you can always tell where the sound is coming from, but this isn't the case with the Nanosat speakers. Their sound bouncing/reflecting technology creates a truly immersive, room-filling sound. In the midsize CNET listening room, we certainly didn't feel the need to use a 7.1 channel array to complete the front-to-back, wraparound soundstage.
