D 7SUR

The dipolar
surround speaker D
7SUR,
use the
same drivers as the
D 7LCR.
This is done to
achieve seamless
timbre matching
with D 7LCR and to
obtain the same
D 7SUR
high level of detail
in the sound reproduction.
D 7SUR is equipped with one 5½" woofer, four 2½"
midrange drivers and two 1" tweeters. At both ends of
the speaker, there is a midrange/tweeter array with two
midrange drivers, mounted close to each other with
the tweeter above them - all in a vertical line.
This is done because the surround speakers, due to
their positioning in relation to the listening position,
must have a different dispersion characteristic than the
front speakers.
The dispersion pattern must be to the sides and
upwards to "paint" the walls and ceiling with sound.
The D 7SUR features a single woofer mounted in the
centre of the front baffle.
This configuration was chosen as conventional dipole
speakers often suffer from poor bass reproduction, due
to phase cancellation between the two woofers.
