As well as letting you get more out of your iPod, iPhone or iPad, the SBX-300 adds a touch of class to your listening space. The unit"s beauty is more than skin deep, with technology found in Onkyo"s top-end hi-fi systems filtering into the portable models. For example, the SBX-300 includes engineering features found in Onkyo"s subwoofer range. Two reflex woofer ducts in the rear add a layer of resonant bass. Low-frequency sound is further enhanced with the unit"s Super Bass booster system. Digital amplifier circuitry and a pair of full-range speakers ensure pristine playback of your music library. Other features include a dust-free digital dock; a comfortable brushed aluminum carry handle; and Active Bass Control to ensure perfectly balanced bass at low volume. With its bold design, big sound, and simple functionality, the SBX-300 will breathe new life into your music collection-wherever you are.
