Background
In-wall loudspeakers are by no means a new invention. Custom installers the world over
have used them for years to enable the design and creation of discrete audio and audio-
visual solutions.

Through the use of in-wall speakers, an installer can create an environment where the
listener need only experience the sound they expect without resorting to more tradition-
al freestanding loudspeakers.

While there are many in-wall loudspeakers currently available, surprisingly, there is very
little design variation and all fall foul of the same constraints and limitations. Meridian
DSP420 breaks that mould with an in-wall loudspeaker that is a rare breed. Inside each
speaker, high technology digital signal processing is used to free the sound from the
walls: the result is clear and open with a wide response.

The DSP420 is a truly active in-wall speaker with separate internal amplification for high
and low frequency bands. The idealised low feedback designs are based on those used
in other Meridian DSP speakers. Rated at 65 and 85 Watts respectively and using careful-
ly selected bipolar output devices, they deliver exceptionally fast bass response and high
resolution. The system has extremely low levels of noise and distortion, which is aided
through careful star earthing.

The power supply includes a substantial toroidal transformer and audiophile-grade
capacitors. These amplifiers are coupled directly to the drive units for the most efficient
delivery of power and the best possible control over driver excursion.

The DSP420 accepts digital input signals up to 96kHz/24bit, including Meridian High
Resolution (MHR) streams from Meridian Surround Controllers, Processors and DVD
Players.
