reflected sound and in addition reduces the influence of the room's standing
wave behaviour.
B.) Improves bass response, by reinforcement against room boundaries, which
makes it possible to, by adjusting speaker's distance from the wall/corner,
regulate the bass quality/quantity to further minimise room influence on the
sound.
C.) Wall or corner positioning makes the speakers less obtrusive in most room
settings.
The exceptional dispersion performance of the drivers which is further supported
by the crossover network allow for considerable flexibility of listening position by
creating a wide, deep and high listening "window" and by maximising the
coupling between horn and room creates an acoustic pressure behaviour similar
to that of live instruments bringing you closer to the musical event.
The AZ-One loads its 5 inch paper cone driver with a quasi quarterwave horn and
combines this with a 3/4 inch dome tweeter and an efficiency of around 93dB, in
a 90 cm high floorstanding dynamic speaker, initially available in black satin finish
only.
The Zero Series speaker range currently consist of 3 models, the AZ ONE (91dB),
AZ TWO (93dB) and the AZ THREE (94 dB+).
As with our existing speaker range we have spent a lot of time making sure that
the power transfer interface between the amplifier (The P ZERO's, naturally, but
also our other low power amplifiers such as the OTO, MEISHU and Conqueror)
and the AZ speakers' load to maximise the acoustic power output to the greatest
possible extent and it is important to appreciate in this regard that good efficiency
ratings are one thing, but in themselves they are no guarantee that you are able
to play loud with a small amplifier; this requires good wideband dynamic acoustic
output conversion to input power applied through the crossover to the drivers
and that is quite another matter which the common efficiency rating does not
adequately describe, and the AZ TWO really does go loud with the 8 watts of the
P ZERO's.
