Sonos will add a deep-bass element to its lineup of wireless music systems when it begins shipping on June 19th the first version of its new SUB – a virtually wireless (save for the power plug) subwoofer that can be set up to work with other Sonos components with just one button and uses a series of proprietary designs and technologies tuned to the company’s amplified products.
The subwoofer, 15.8 inches by 15 inches and just 6.2 inches deep, looks from the front like a square keyhole. Its center space allows for two inward-firing “force-cancelling” drivers to work face to face, supported by dual acoustic ports tuned to maximize acoustic volume. The drivers are powered by two Class D digital amplifiers that work inside a proprietary resin cabinet reinforced at the center slot with an aluminum frame. The subwoofer may be used either in standing position or laid flat and slid under a couch, said Chris Kallai, director of engineering project management and manager of acoustics for Sonos. All filter settings, active equalization and time alignment are done digitally with digital signal processing (DSP). “The sound is sculpted in the software,” he explained.
The product is controllable from a computer, smartphone or tablet device if one of several free Sonos Controller apps is downloaded.
