Digital Trends have published a review of the Kerchoonz K-box portable speaker. 'The K-box, which is roughly the same size as an iPhone (it measures 4.5 inches wide, 2.2-inches high, and 0.8 inches thick), is outfitted with a 1/8-inch audio input and mini USB port for recharging its internal battery. (The company claims a fully charged battery will deliver 20 hours of use.) A conventional speaker produces mid-range and high frequencies, which emerge through a grill on its top surface. SFX's Gel Audio transducer produces bass frequencies, and the full spectrum of sound is propagated across a thick gel pad (think Dr. Scholl's insoles) on the back of the K-box. Sound is then transferred to whatever surface the K-box is resting on. Put your ear to the surface and you'll ear music emanating from it just as if it were a conventional loudspeaker.'
