Meridian DSP-8000

These speakers are in amazing condition, one of the speakers has a small chip on the paint but it is minor, please refer to the picture.

we will ship them to any part of the US for Free.

Priced at $65,000 a pair, the Meridian DSP8000 speakers are without question an ultimate high-end audiophile product. It is important to note that these speakers being "active" include a host of internal amps, including three 150 Watt power amps for the bass drivers as well as two 100 Watt amps for the mid and high frequency drivers. Internally, there are also four 24 bit digital to analog converters. Each speaker is capable of upconverting lower resolution audio signals to a 24 bit "HD" signal right inside of the speaker cabinet. Much like a Wilson WATT Puppy (a passive or non-amplified speaker), the Meridian comes as a two-part speaker system with a top and bottom component. There are six bass drivers, a six-inch midrange driver and a one-inch dome tweeter to make up the driver compliment. The Meridian DSP8000's are controlled by RS-232

Digital Signal Processing

Digital Signal Processing, or DSP, is a technique pioneered by Meridian in hi-fi products for achieving extremely accurate reproduction of audio signals using high-precision mathematical processing.

DSP allows sophisticated processing to be performed without any of the cumulative noise or degradation that inevitably occurs, even with high-quality analogue circuitry. In addition, the signal improvement techniques incorporated in the Meridian DSP loudspeakers would be virtually impossible to implement in analogue circuitry.

The Meridian DSP loudspeakers take advantage of DSP for several different functions: To remove timing variations from the incoming digital signals (de-jittering).

·         To split the frequency band between bass, midrange, and treble drivers (crossover).

·         To perform filtering or adjustment of the frequency response; eg treble or bass.

·         To provide volume control to 48-bit precision.

·         To provide digital protection of the loudspeakers against high-level low-frequency transients.

·         To perform electronic equalisation.

If you are using the Meridian DSP loudspeakers with a digital source, such as CD or DVD, the signals remain in digital form until the last possible stage.

DSP loudspeaker drivers

Each DSP8000 loudspeaker uses six multiple highefficiency long-throw custom bass drive units. The bass units are mounted symmetrically in pairs on the sides of the bass cabinet, cancelling vibration in order to minimise interference with the mid-range and treble units.

The treble and mid-range drivers are mounted in a separate sealed head assembly. The treble unit is a semi-horn-loaded composite dome design with a silver voice coil.

The mid-range unit incorporates a cone made from a uniquely light and stiff combination of polymers to give unparalleled transparency. The Special Edition model uses variations of the mid and bass units fitted with solid metal rings that clamp the drivers more firmly in the cabinet. It uses a similar treble unit but with a lighter, more rigid, beryllium dome. This combination allows the Special Edition loudspeakers to have a more controlled transient response across a wider frequency range.

Power amplifiers

The speakers are driven by five independent highpower low-feedback power amplifiers mounted on a multi-finned extruded heatsink. The combination of idealised magnetic design, careful star earthing, and very fast output devices gives the amplifiers extremely low noise, high detail, and fast bass.

The whole electronic assembly is supplied from two substantial toroidal transformers feeding high-quality audiophile-grade capacitors.

Meridian High Resolution (MHR)

The DSP8000 loudspeakers support Meridian High Resolution (MHR), to allow you to connect to other MHR-compliant Meridian products to take advantage of high-rate audio sources, and provide the additional benefits of lower jitter and improved sound quality on all sources.

MHR is a proprietary secure encoding format that uses encryption and anti-copy methods to provide a secure copyright protection environment, and allow the secure transfer of audio streams within a Meridian-only system for playback only
