Designed specifically for the Tivoli Model Satellite Radio and Tivoli Model Three AM/FM clock radio-both of which feature only a signle built-in speaker. This top firing stereo speaker lets you hear what you"ve been missing. Simply plug the 15 foot calbe into your Tivoli radio"s right-channel RCA speaker output to enjoy rich, full-bodied, hi-fidelity stereo sound. The frequencies sound just right thanks to the 3 inch full range driver, which is timbre matched to the Model Satellite and Model Three drivers. Meanwhile, the top-firing orientation offers a nice alternative to traditional front-firing speakers, particularly in rooms with plenty of tabletop or shelf space (the Model Satellite and Model Three"s speakers are also top-firing). Thanks to the extra-long 15 foot cable, you can locate the speaker far apart from the main unit, ensuring a truly expansive stereo image and convicing soundstage.
