Meridian subwoofers The Meridian SW1600 and SW5500 combine the finest materials with state of the art design to create what we believe are the ultimate subwoofers, emphasizing extreme bass, depth, clarity, control, and articulation. Each subwoofer provides both digital and active analogue inputs, allowing them to be connected either to a digital surround controller or digital source with a digital coax output, or to an analogue preamplifier or surround controller with either phono or balanced outputs.
Digital Signal Processing The subwoofers employ 96kHz/24bit digital to analogue conversion and accept digital inputs up to 96kHz including those carrying MHR signals. Separate analogue and digital power supplies are used to feed the subwoofer’s precision electronic circuits, ensuring that both high and low power sections receive continual smooth supply. If you are using the subwoofers with a digital source, such as CD or DVD, the signals remain in digital form until the last possible stage.
Subwoofer drivers  The subwoofers are based on 300mm (12") high-efficiency long-throw custom drive bass units. The SW1600 uses a single driver, and the SW5500 uses two drivers in a single enclosure. In each case the enclosure is sealed for maximum flexibility of positioning.
Power amplifiers The speakers are driven by Class G high efficiency ultra low output impedance amplifiers. The combination of idealized magnetic design, careful star earthing, and very fast output devices gives the amplifiers extremely low noise and fast bass, optimized for both music and movie soundtracks.
The whole electronic assembly is supplied from substantial toroidal transformers feeding high-quality, audiophile-grade capacitors. Cabinet Each subwoofer is carefully constructed from 22mm MDF with inert basket bracing and resin damping to produce an ultra-rigid cabinet. The subwoofer is finished with a 6mm annealed glass plate top and thick veneered MDF sides bolted to the main cabinet, giving extremely low levels of cabinet resonance.
