DSP320 Ceiling/In-Wall Loudspeaker

Featuring an elegant profile, the DSP320 is perfect for delivering high quality music discretely. Its square format and compact design makes it perfect for mounting in a wall or ceiling. The DSP320 delivers full DSP loudspeaker performance, while the back-box and frame system allows for easy installation and precise positioning.
The DSP320 inherits the latest technologies from Meridian’s floorstanding loudspeakers including Enhanced Bass Alignment (EBA) and Centre Elevation, providing incredibly lifelike and spacious sound.


Meridian has been designing and creating state-of-the-art audio and video home entertainment systems for over 35 years. Meridian products not only sound unique; they look unique. Great industrial design is as much at the heart of the products as the electronics or the principles behind it. The design is not only there to look good: it also contributes significantly to the smoothness and sweetness of the sound.

'-Outstanding performance. Two powerful 80W class D amplifiers with DSP provide a maximum output level of 106dB at 1m.
-Off axis dispersion and even distribution of sound – creates wide listening area perfect for large spaces.
-Left + Right mode which combines both stereo signals and outputs them perfectly from one speaker.
-Easy to install and compact footprint – only 100mm deep and 300mm square, offers huge flexibility on in wall and in ceiling applications.

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.

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.

-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.
