Meridian DSP7200 SE Active Speakers
The Meridian DSP7200 SE Active Floorstanding Speakers demonstrate the ultimate expression of high-resolution audio that can be achieved within a loudspeaker of its size.
Four powerful wide range 150W amplifiers deliver a maximum output level of 118dB at 1m.
Light weight, dual voice coil, Beryllium tweeter for refined high frequency performance (up to 32kHz).
Clamp rings ensure that the bass and midrange drivers are isolated from the cabinet, giving the most controlled and detailed sound possible.
New extended-bandwidth analogue electronics, optimised to deliver maximum performance from high-resolution recordings.
The additional DSP device, used by the Special Edition loudspeakers, doubles the available processing power allowing all audio, including MQA Core streams, to be rendered at 176.4/192kHz regardless of the incoming sampling rate. This results in increased resolution, detail and clarity to provide maximum fidelity from music and movies.

Enhanced Bass Alignment (Eba)
High or low, all sounds travel at the same speed, so all the sounds from a live musical event arrive at your ear at the same time, whatever frequencies they contain. Loudspeakers, however, have a problem when playing low frequency sounds at the same time as mid and high frequencies – the bass arrives late, and the deeper the sound, the later it arrives. This delayed bass causes music to lose its impact and reduces the sense of the recorded space – it is often described as “boomy”.
The goal is to have time-accurate loudspeakers, where all reproduced frequencies start and end at the same time. In a loudspeaker, this timing is affected by the crossover, driver, and enclosure type. To eliminate the delay between low, and mid and high frequencies, Meridian has designed a combination of digital filters and time delays for the mid and high frequencies. This solution enables the mid and high frequencies to “wait” for the low frequencies, delivering perfectly-timed music playback.
Mid and high frequencies are delayed to time-align them, while upper bass is delayed with a special type of patented filter. These features must be implemented entirely in the digital domain, making them impossible to achieve in any passive or analogue-active loudspeaker design.
Enhanced Bass Alignment provides accurate time-alignment of the drivers in the system, delivering exceptional imaging and a clear, transparent, more life like sound.
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.
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.
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.
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.
MHR
A patented Meridian audio format that combines high bandwidth, security and low jitter. MHR gets the highest possible sound quality in playback systems that use Meridian and enables the encoded transmission of PCM, MQA and DSD.
Meridium
Loudspeaker enclosures often vibrate, colouring the sound, making it less lifelike. Meridians 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.
