POWERSUB 315
Suitable active and passive subwoofers
implemented as vented direct-radiating
enclosures permit flexible system
configurations.
The reflex systems of these subs, when
compared with conventional bass reflex
ports, are characterized by less flow loss
and less wind noise. High sound pressure
levels at very low frequencies are generated
with considerably less distortion than is
the case with conventional bass-reflex
ports.

The passive varieties can, as a result of
their integrated low-pass filters, simply
be operated parallel to the various passive
full-range boxes.
The active single-channel subs possess
crossover outputs for the creation of
active three-way systems with e.g. the
models D 8A or D 11A. The three-channel
subs already possess the requisite power
amplifiers for passive tops and permit in
the simplest manner the configuration of
so-called 'satellite systems'.
