Product Description

Meridian DSP640.2, is the second generation of DSP640, offering great flexibility and optimum performance from any source plus high SPL and strong bass performance for full range sound without needing an additional subwoofer.

It is powered by Merdian's patented "Class-M" DSP engine and features "Dynamic" Hi-Res amplifiers bringing Meridian's signature sound to any living or cinema room discreetly while the L+R function makes it an ideal soundbar solution.


DSP640.2 features octa-amp DSP architecture comprising eight powerful amplifiers built into the speaker which provides 100W RMS (8 Ohms per driver) along with >105dB sensitivity at 9m. Full range sound is delivered with bass extension down to 35Hz. Optimised DSP enables horizontal or vertical mounting making this ideal for soundbar or centre channel purposes.


With its extensive R&D programme, Meridian has pioneered the development of a host of innovative audio technologies many of which feature in today’s Meridian products. Meridian loudspeakers feature a complete, matched audio system with efficient DSP crossovers, multiple DACs and driver-specific amplifiers for higher overall quality, less power use and the performance of a traditional loudspeaker eight times the physical volume.


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

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.

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.

Wide Range Driver

Loudspeakers use crossovers to “divide” music into bands their drivers can reproduce. This introduces distortion, reducing sound quality – particularly on human voice recordings. Designing a single driver for both mid and high frequencies made a crossover within the vocal range unnecessary, avoiding distortion and reproducing more lifelike vocals at all volume levels.

Enhanced Bass Alignment

Loudspeakers have a problem when playing low frequency sounds at the same time as mid and high frequencies, the bass arrives late especially for deeper sounds. This delayed bass causes music to lose its impact and reduces the sense of the recorded space often described as “boomy”. The goal is to have time-accurate loudspeakers where all reproduced frequencies start and end in time.

To eliminate delays, Meridian uses a combination of digital filters and time delays. Mid and high frequencies are delayed to time-align to lows, while upper bass is delayed with a special type of patented filter delivering perfectly-timed audio. These are implemented entirely in the digital domain making it impossible to achieve in any passive or analogue-active loudspeaker design.
