BlackBox Black Box is a high-power amplifier speaker system that can be easily connected to your mobile phone, TV, Xbox or any product with audio output via cable or wireless Bluetooth (Bluetooth Beam). Unlike large-scale production of plastic speakers, the black box is made of 0.75-inch medium density fiberboard (MDF wood), which is the best speaker enclosure material and can eliminate unnecessary energy and vibration, thus enabling the black box to produce clear sound even at very high volume without distortion. The black box was designed from scratch by the U.S. engineering team of BlackBox in San Diego, California. The team has over 40 years of comprehensive and shared experience in the fields of mechanical, acoustic and electronic engineering.
