NOTE: Includes passive crossover (no amps).
Designed for continuous high power operation in a correctly
constructed acoustic space, the M3 represents the fruit of a research
and development program aimed at elevating main monitors above the
realm of modified PA speakers. A pair of 300mm bass drivers are
perfectly complemented by two 150mm piston midrange drivers employing
massive 75mm coils. High frequencies are accommodated by a high power
version of the 28mm Esotec T-330 DA dome tweeter, which enjoys a
reputation as the finest dome tweeter available. All drivers are
ferrofluid cooled, a benefit only made possible on low frequency
drivers by the use of custom designed ferrofluid compounds applied to
very tightly tolerated voice coil gabs – a feature absolutely unique to
Dynaudio Acoustics.
The result is a very clean, dynamic and powerful speaker in which
common problems, such as cone break up, thermal compression and phase
misalignment have been almost eliminated. Frequency response is full
and flat, and the overall transparency of sound leaves no doubt that
the M3 truly advances the art of monitoring at high levels without
sacrificing quality at more relaxing volume. Levels from 85 to 120dBA
exhibit essentially identical timbre allowing total confidence in mix
decisions regardless of monitoring level.
The M3 Main Monitor is available in both Passive and Active
versions (THIS LISTING IS FOR THE ACTIVE VERSION). Both versions employ
the same sophisticated impedance corrected passive crossovers between
midrange drivers and tweeter. The Passive version has internal links
for simple adjustment of low frequency levels, and is primarily
intended for user installation on rigid stands within a control room,
although soffit mounting is entirely feasible. The bi-amped Active
system uses an active external crossover offering full equalization
capabilities together with dual-band electronic driver protection.
Features:
- Unique linear phase and frequency response.
- Every monitor matched to any other monitor within กพ 1.5dB.
- 28mm ESOTAR soft dome tweeter with aluminum voice coil.
- Dual 150mm magnesium silicate impregnated polypropylene (MSP) midrange drivers with 75mm voice coils.
- Dual 300mm polypropylene bass drivers with exceptionally large
100mm aluminum voice coils, offering dramatic improvements in power
handling, bass response and distortion figures over conventional
systems.
- Gold plated professional binding posts accepting heavy-gauge speaker cable.
- Heavy internal damping for minimum cabinet resonance.
- Thermal protection of the tweeter.
