DSW600 In-Wall Digital Active Subwoofer
Fast, Dynamic, Powerful

The DSW600 is a shallow-depth, digital active in-wall subwoofer designed to handle the most bass heavy music and movie soundtracks with ease. Deep, powerful and exciting bass is delivered with perfect timing down to 24Hz thanks to Meridian’s unique ‘DSP’ advantage and Enhanced Bass Alignment Technology.

The DSW600 can integrate into a variety of installation applications, it delivers impactful bass in any room size and as part of any loudspeaker configuration; it can be used to augment the bass from other loudspeakers in both two-channel and surround-sound systems, and it can be used to play the dedicated LFE channel - either on its own or when used in multiples.

On-board DSP supports simple integration with any Meridian Architectural loudspeaker to provide truly full-range performance from a two-box in-wall solution.

Immersive, powerful and accurate bass down to 24Hz.

Bass protection provided by on-board DSP prevents the subwoofer from overdriving even at the most extreme bass levels.

Sealed cabinet built from birch plywood with heavy internal bracing, delivers a reliable, repeatable performance regardless of installation.

We are the masters of Digital Signal Processing

With its extensive Research and Development programme Meridian has pioneered the development of a host of innovative audio technologies many of which feature in today’s Meridian products.

As pioneers and leaders in the field of Digital Signal Processing (DSP) technology, Meridian is able to deliver your music authentically to recreate the passion and involvement of your musical moments. Power-efficient, active DSP crossovers are individually tailored to distribute music to each speaker, bringing your music to life.

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

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.

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.

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.

Uses a complex digital filter to double the rate of samples from the source to improve resolution of the finer details in the record. This means that even with a standard source such as CD using our upsampling technology we are able to significantly enhance the listening experience.

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.
