DM620

Floor-standing loudspeaker system

Product Summary

●

The 600 series takes its place in a distinguished family tree that includes the world renowned
Matrix 801 and the Matrix 802. Something of this superb pedigree was bound to rub off.
In the same way that a luxury car benefits from racing technology, a 600 series loudspeaker
speaker system brings with it the pleasure of acquiring the worlds leading acoustic expertise
with inherent good value that will be music to your ears.

●

The DM620 comprises of an 8in bass/midrange driver with a reinforced polypropylene
diaphragm of critical flare delivers pure, crisp sound free from audible coloration. The bass
performance in the 30-litre enclosure is augmented by means of an 8in passive drive unit.

●

The tweeter is a 26mm metal-domed tweeter originally developed for the highly successful
Matrix 801 studio monitor. This high frequency unit has been specially created to permit
higher power handling.

●

An integral feature is magnetic fluid cooling which combats compression by
reducing the temperature of the delicate voice coil in the tweeter at high
frequencies.

●

The practice of flush-mounting units into stylised moulded baffles
has been implemented in the 600 Series. This, together with the bevelling of
baffle edges, helps to fight diffraction and produce a cleaner sound. The front
polymer compound baffles and the high density fibreboard sub-baffles combine
to bolster the structure, and reduce radiation from mechanical cabinet vibration.
This is further improved by internal bracing of the cabinet walls.

●

The proven provision of being able to bi-wire or bi-amplify the system is
present. Two sets of top quality, gold plated terminals are present to enable
individual inputs for the high and low frequency units.
