INTRODUCTION

Meridian subwoofers

The Meridian SW1600 and SW5500 combine the ﬁ nest materials with state

of the art design to create what we believe are the ultimate subwoofers,

emphasising 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 preampliﬁ er 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-efﬁ ciency 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 ﬂ exibility of positioning.

Power ampliﬁ ers

The speakers are driven by Class G high efﬁ ciency ultra low output

impedance ampliﬁ ers. The combination of idealised magnetic design,

careful star earthing, and very fast output devices gives the ampliﬁ ers

extremely low noise and fast bass, optimised 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 ﬁ nished with a 6mm annealed glass plate top and thick

veneered MDF sides bolted to the main cabinet, giving extremely low levels

of cabinet resonance.
