Kicker ik500 Speaker System - with excellent quality sound. New condition. Connect with player (phone, iPad, computer, CD player, iPod, etc.) by USB, RCA, or earphone jack. Bought for a project that didn't happen. Used only 3 times. All original packaging and accessories are included. New price: $380. Selling now for $150. I am a musician with a critical ear for sound quality. I chose the Kicker out of many, for its excellent quality sound, including at high volume. PC World review: "The iKick iK500 is exactly what we want a speaker system to be: a simple, straightforward device that provides clear, precise sound at near-earthquake-inducing levels. "The company claims that the iKick iK500 is louder than other iPod speaker systems that are available, and — unless our ears deceive me — it may be right. "The iK500's black, slightly boxy design features a recessed iPod dock between two speakers. It comes with eight adapters for connecting most iPod models; you can connect MP3 players or CD player via the auxiliary and stereo RCA inputs on the back of the device, too." [including USB] " ... the quality of the sound (and of the bass) was excellent all the way to the end of the dial, with no warbling, fuzzing, or muddying of the sound quality at any point." - from: http://www.pcworld.idg.com.au/review/kicker/ikick_ik500/256488/
