SW5500 subwoofer above, and SW1600 below.

Meridian’s SW1600 and SW5500 combine the ﬁnest 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 Meridian digital surround controller or digital source with a digital coax output, or to an analogue preampliﬁer or surround controller with either phono or balanced (XLR) outputs.

The subwoofers’ digital inputs employ 96kHz/24bit digital to analogue conversion and accept inputs up to 96kHz – including Meridian High Resolution (MHR) signals. If you are using the subwoofers with a digital source such as CD or DVD, these inputs allow signals to remain in digital form until the last possible stage.

Separate power supplies

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.

The entire electronic assembly is supplied from a substantial toroidal transformer feeding high-quality, audiophile-grade capacitors.

Optimised for both movies and music

The subwoofers are based on 300mm (12in) high-efﬁciency long-throw custom bass drivers. The SW1600 uses a single driver, and the SW5500 uses two drivers in a single enclosure. In both cases, the enclosure is sealed for maximum ﬂexibility of positioning.

The speakers are driven by Class G high efﬁciency ultra-low output impedance ampliﬁers. The combination of idealised magnetic design, careful star earthing, and very fast output devices gives the ampliﬁers extremely low noise and fast bass, optimised for both music and movie soundtracks.

The use of two drivers in parallel, combined with the ultra-low output impedance of the ampliﬁer, allows the SW5500 to deliver RMS power outputs in excess of 500W.

Rigid cabinet design

Each subwoofer is carefully constructed from 22mm MDF with inert basket bracing and bitumen damping to produce an ultra-rigid, damped cabinet that minimises colouration.

veneered MDF sides are bolted to the main cabinet, resulting in extremely low levels of cabinet resonance.

Applications

The SW1600 and SW5500 can be used to complement Meridian DSP Loudspeakers in both stereo and surround systems. In addition, the analogue input capability makes them ideal for analogue systems too.

and the SW5500 is ideal as a mono subwoofer for a Meridian Digital Theatre system, in particular to give exciting cinema effects and added realism in DVD movies.

The recommended conﬁguration for music is to provide two subwoofers, one for each of the main left and right channels, for a superb stereo image. The SW1600 is ideal for this application.

In a large system, multiple subwoofers can be employed to provide even more impressive effects.

Accessories

The SW1600 and SW5500 are supplied with feet, spikes and castors, allowing maximum versatility of mounting and position, including built-in or cabinet installation.

Included are the cables required to use the subwoofers in a Meridian system.

The subwoofers are ﬁnished with 6mm annealed glass top-plates, and thick
