This particular unit was sold new ($6,500) to one of our clients many years ago and was well cared for. This is the 96/24 version.

A move and downsizing prompted the client to return it to us, and wow is it as nimble and powerful as we remembered.

This a self powered speaker capable of working in a center, left, or right position (LCR).

While it’s meant to sit upright, you certainly could lay it on its side and use it as a horizontal center speaker.

It's finished in a gloss black glass on the top, with dark wood on the sides.

In near perfect cosmetic condition with no significant signs of abuse or wear (There is a small indentation in the top left visible in the pictures).

It was fully tested here in our shop and listening room and is working like the day it left the factory.

We do not have the original Meridian packaging, but it will be professionally packed for safe arrival in a high quality box with our custom-made expanding Instapak foam inserts.

We'lll include a new remote, instruction manual, power cable, and digital connecting cable as shown in our last photo.

Background
Meridian has long led the market with their highly acclaimed DSP loudspeaker designs. The current models have won a steady stream of awards. In fact the DSP6000 – which was introduced in 1990 – is the only loudspeaker to hold the coveted Stereophile Class A rating for eight successive years.

The Meridian DSP loudspeakers uniquely combine excellent acoustic and drive- unit technology, with multiple built-in power amps, performance-enhancing DSP and digital conversion systems.

Meridian DSP5500
The DSP5500 is a single-box DSP loudspeaker, designed to provide performance similar to the highly popular DSP6000. This new model is a front-facing format that can be effectively built into system cabinets – DSP functions are provided to correct the frequency response in a number of locations. A unique removable wood and steel side panel arrangement allows for easy colour changes or custom finishes. The side panels are bolted in place; in addition to providing magnetic shielding, the resulting solid, stiff cabinet provides massive acoustic damping, giving the speaker remarkable mid-range transparency.

Acoustic system and format
The DSP5500 is a powerful 3-way active acoustic reflex system. The bass system uses two 200mm long-throw composite bass drivers. The cabinet vents through a floor-level wide-area coupling slot; this configuration – along with the active and DSP correction – maintains smooth powerful bass in the room down to 30Hz with very low mid-range colouration.

The mid-range is mounted in a separate enclosure and uses a custom 160mm polypropylene driver. The tweeter is the Meridian 25mm aluminium-dome, silver-wire tweeter used in all the DSP loudspeakers. Each of the four drive units has its own 75W power amplifier.

The main cabinet is constructed from high-density MDF. A unique ‘sandwich’ construction method clamps sheet steel all over the cabinet sides between the main cabinet and the real wood veneer side panels. This technique results in a very inert cabinet and provides exceptional magnetic screening – allowing the DSP5500 to be placed immediately next to small or large TVs. The top of the cabinet has an attractive 4mm plate-glass top.

Electronic system
Each speaker incorporates an electronic panel in the rear part of the cabinet. The speaker accepts digital signals and there are two inputs. The input receiver uses a FIFO memory buffer for the lowest possible jitter from almost any source.

The crossovers, equalisation, tuning for a number of locations including cabinet installation, protection and tone controls are all implemented in a 100MHz Motorola Digital Signal Processor (DSP) inside each speaker. The DSP feeds carefully tailored individual signals to the bass, mid and tweeter DACs. The DSP5500 uses four Meridian Class-A discrete 75W low-distortion power amplifiers to individually power the drivers. The electronics are powered by a high-current toroidal transformer through a custom high-speed power supply.
