were necessary in order to achieve the required SPL
from the compact woofer.
The woofer operates without break-ups until 2k Hz,
which is far beyond its working range as the x-over
frequency is 400 Hz.
Instead of a dust cap, the driver features a solid
aluminium centre plug. This construction results in
effective heat disposal and prevents airflow obstruction
when the diaphragm moves.
The result is clean, natural and detailed sound
reproduction.
(Sub)Woofer
The 15" woofer features a
vented
double
magnet
system and a capton voice coil
former, 65 mm in diameter
and 40 mm long. The 4 layer
voice coil and the double
magnet system make the
D 7SUB Woofer with transducer
motor of the driver very
powerful, capable of very high
power handling.
The diaphragm is made from
polypropylene which is
very rigid and the foam surround allows fast movement
at its low frequency working range.
