B&W DM3000 high end

---

Prachtige high end speaker (bruin) (zelden te koop aangeboden) die erg neutraal is maar ook veel detail heeft.
Geen irritant hoog of laag maar zoals de muziek moet klinken.

Wegens ruimtegebrek gaat de DM2000 of DM3000 eruit, zie mijn andere advertentie.

Orginele bruine stofdoek is vervangen door grijs.

Is makkelijk te vervangen.

Hoogte 98,5 cm

From The Vendor
All the vast knowledge and expertise gained from the experience of building loudspeaker systems that have led the world for two decades has gone into the creation of models DM2000/DM3000.They are at the top of the exciting new generation of B&W Digital Monitors.

DM2000 is a floor-standing model incorporating completely new, inter-related concepts in enclosure styling, drive units and equalization. A true digital monitor with performance and appearance further enhanced by the most recent advances in B&W loudspeaker technology.
Sensitivity: 87dB.
Extended linear response to the accepted standard set by our famous professional monitor, Model 801.
ETD: electronic time delay.*
ETD: supersedes physical stepping, permits a flat
front baffle.
Optimization of the diminishing sound source as frequency increases.

Two completely new acoustic drivers plus an acoustically driven radiator (ADR) to further augment drive unit area in the extreme bass.

• ETD (electronic time delay) realization of an ideal

Several years ago, our DM6 was the precursor of all linear-phase loudspeakers and it is still widely copied around the world.

Meantime, our design team has been quietly working towards an elusive ideal: the correction of inter-unit time delay without the C1isadvantages -acoustical and cosmetic - of the stepped baffle configuration.

The ideal is now realized in ETD (electronic time delay) in which Acoustically, sharp boundary changes are advantageously avoided and we come nearer to minimum phase transfer characteristic between bass, midrange and tweeter.

t Principle o f the acoustical triangle and another significant advance

DM2000/DM3000 embody another "Significant advance towards an acoustical idea. The new drive units are laser-optimized to behave as a source which diminishes in size as frequency increase. This results in:
- Smoother directivity i Clex.
- Better defined stereo perspective
- Improved depth Imagery.
- Broader options for seating.
Behind this development is the principle of the acoustical triangle. The higher the sound frequency, the smaller the source of that sound.
At the base of the acoustical triangle are the ADR and bass drivers, which take care of the very lowest frequencies (say bass drum). At its apex is the center of the tweeter dome, which handlesthe very highest frequencies (triangle for example).
