Availability: In stock

We Aim To Dispatch Goods Within 3 Working Days

£3,500.00

Building on the performance of the DSP520, the DSP640 is designed for the most demanding of listeners. The DSP640 shares the same visual width and sonic character of the DSP520, making them perfect companions in a Meridian Digital Theatre.

In addition to Meridian’s unique Wide Band driver technology, the DSP640 features dual-long throw woofers for extended bass, and dynamic range that is perfect for today’s high-resolution music and movies. All of this adds up to floor-standing loudspeaker performance, without a single inch of floor space.

Full Description

 

 

The DSP640 shares the latest technologies from Meridian’s DSP7200 Loudspeaker, including Enhanced Bass Alignment and Centre Elevation, providing incredibly lifelike and spacious sound. This makes the DSP640 a perfect choice for stereo or full surround with virtually no visual impact to the decor.

Meridian’s In-wall Loudspeaker range was created to provide no-compromise performance in an environment where floor space is either at a premium, or a conventional loudspeaker is simply not suited.

DSP640, like the entire range of Meridian In-wall Loudspeakers, is built around an aluminum enclosure. This enclosure forms the back of the loudspeaker itself, while the drivers are mounted to another metal extrusion. This provides an extremely stiff “box” and with special dampening material, has no sound of its own to color the music. This makes it ideal for an in-wall loudspeaker.

A slender, paintable grill is magnetically attached to the loudspeaker. This allows for the grill to be custom painted or wallpapered to match any décor, while the magnetic mounting system ensures secure grill installation without unsightly hardware.

Technology:

The DSP640 features amplifiers that are optimized for each driver and the frequency range that they are tasked to play. This “active” approach provides the benefits of a loudspeaker with extended bass, and output volume, equivalent to a passive loudspeaker of eight times its physical size. 
Rather than use a passive crossover that robs the music of resolution and detail, the DSP640 implements this in the digital domain, thereby avoiding any loss to the music.
 
 

DSP Loudspeakers

The traditional setup – amplifiers driving passive loudspeakers – is inefficient,

limiting sound quality. Meridian loudspeakers contain a complete, matched audio

system with efficient DSP crossovers, multiple DACs and driver-specific amplifiers,

giving higher overall quality, less power use, and the performance of a traditional

loudspeaker eight times the physical volume.

SpeakerLink

Traditional audio systems often require large, expensive cables to maintain their

performance. Meridian's SpeakerLink uses an “Ethernet style” cable that delivers

pristine digital sound and control down a single cable between Meridian components.

The result is simple, unobtrusive, and cost-effective cables that are easy to install

Meridium

Loudspeaker enclosures often vibrate, colouring the sound, making it less lifelike.

Our most advanced loudspeakers use a cabinet construction material unique to Meridian:

Meridium features highest-grade laminated plywood layers bonded to an aluminium core,

allowing the loudspeaker to reproduce music accurately without adding its own sound.

Triple FIFO Buffering

Each sample of a digital recording must remain evenly spaced in time. Unfortunately, timing

can vary, especially when reading discs. This is “jitter”, degrading music's sense of space

and diminishing realism. Meridian's multiple “First In, First Out” buffering system minimises

jitter, ensuring perfect timing and improved clarity. You enjoy a clearer feeling of the instruments

and their interrelationship.

Meridian High Resolution (MHR)

MHR was the first approved encryption method for transferring high definition digital audio

between components. Previously, it had to be in the analogue domain, reducing quality. MHR

allows secure movement of high resolution digital audio within a Meridian system, without

compromise, improving quality by reducing cyclic repetition.

Meridian Apodising Filter

Filters are critical in digital audio. Commonly they introduce distortion and harshness because

of "pre-ringing". Early digital recordings suffer from harshness too, due to primitive filters. After

painstaking research, Meridian developed a special filter that avoids pre-ringing, so it can be

steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings

old and new.
