Meridian M33 User manual

Meridian M33 and M33C
The M33 Analogue Active Loudspeaker based on a long tradition of highly
acclaimed active loudspeaker designs dating back to 1977 when Meridian
launched the M1, it’s first product.
Electronics
The electronics of the M33 are designed using the very latest techniques.
Components are carefully chosen and include many polypropylene capacitors
and Van den Hul internal wiring.
Both balanced and single ended inputs can be found on the back panel allowing
for connection to a wide range of controllers and pre-amplifiers.
At the heart of the M33 are the twin amplifiers, which make use of our latest
research into idealised low feedback amplifier design. These give high power -
85W Bass and 65W Treble. Careful attention to star earthing and high speed
bipolar output devices combine to give very fast bass and high resolution. The
system has extremely low levels of noise and distortion. The power supply
includes a substantial torroidal transformer and audiophile grade capacitors.
Acoustics
Corey Greenburg said about the M33, “The first thing I noticed about the M33s
was their startlingly clear and detailed midrange”
The cabinet is manufactured from precision cast and extruded aluminium. This
has incredibly low levels of low frequency cabinet resonance. Additional high
frequency damping gives the whole system exceptionally little cabinet
colouration, for excellent mid-range transparency.
The bass drive units are two parallel 5" woofers with cast alloy chassis and
carbon fibre cones. They have very large shielded magnets that provide excellent
drive and control. The tweeter is a very high quality 1” aluminium dome with a
Neodymium magnet and a protective grille. It is extremely well matched to the
woofer and also tonally very compatible with the other speakers in the Meridian
range.

Applications
The M33 is designed for use in many different types of system and so has been
made with ease of installation in mind. It can be used either vertically or
horizontally mounted as a centre channel. If ordered as a centre, it is supplied
with a plinth, which gives rigid support and tilts the centre channel towards the
listener, whether sited above or below a television. It can also be wall mounted
using an Omnimount 75 Series bracket.
The remarkable bass extension of the M33 makes it a wonderful stereo system
for moderate sized rooms, or larger rooms if supplemented with M1500 or M2500
subwoofers.
