For excellent omnidirectional outdoor stereo sound without messy wires, the Acoustic Research AW-811 single speaker provides patented 900 MHz wireless technology, which lets your signal transmit through walls, floors and ceilings at distances of up to 300 ft. (depending on source) inside your house or outside with no line of sight required between the speaker and transmitter. Plus, you can put the speaker wherever you like; its water-resistant design lets the AW-811 thrive outdoors and indoors, and in humid areas such as kitchens and baths. Plus the speaker will tune to the transmitter automatically, at the touch of a button. Since this comes as a single speaker, you can adjust sound with the stereo/mono switch to optimize the sound of the digital amplifier (second speakers, required for stereo sound, are sold separately).

Controls include one easy to use knob for the 3-in-1 power, tuning, and volume control, and a channel select switch that lets you change transmission frequencies to operate more than one 900 MHz product within the same area. To help eliminate extra noise, the speaker comes with a RF noise reduction system. This speaker is also designed to be moved; there's a built-in folding handle, a non-skid surface (so you can use it as a tabletop), and it runs on either 8 C batteries (not included) or an AC adaptor. The batteries self-charge when the unit is plugged in. You can even take the speaker inside and use it with any RCA-compatible device, such as your TV, DVD player, A/V receiver, VCR, portable CD player, computer, and more.
