Why buy an active
subwoofer with
integrated DSP?
To find an acoustically acceptable listening room is
a big problem. Normally you can not change your
living room that much and you need to accept a lot
of losses in the sound quality. This is a known fact,
but many brands do not touch that issue because it
is not easy to solve this problem with traditional
analogue technology.
It’s impossible to construct a normal analogue
subwoofer to sound perfect in every room.
Every room has unknown and unique acoustical
characteristic that affects the sound quality. The
biggest problems are in the low-frequency
spectrum. A normal (not acoustically treated) room
have severe resonances and deeps in spectrum
caused by so called standing waves. Dependent on
listening position it produces wrongly balanced
sound.
The frequency response of a good loudspeaker
should be in the range of ± 3dB, but a normal room
can have variations of ± 15dB. This leads to the
conclusion that even a very good loudspeaker can
sound poorly in a "bad" room. And the fact is that
the most regular rooms have strong acoustical
problems.
To build a perfect listening room is extremely
expensive.
With the DSP technology we can create a good
balanced sound in every room.
Amplifier
We have equipped the XTZ W12 DSP with a very
powerful amplifier with 400 Watts and a big
cooling flange for effective cooling. For professional
use (studio, PA etc.), it is equipped with a balanced
input. The terminal connectors are gold-plated and
very solid.
To achieve a high power and a long durability, the
amplifier is built with a large ring-coil transformer,
large electrolyte capacitors, and has MosFet
transistors in the power stage
.
The woofer/ driver
The XTZ W12 DSP is equipped with a powerful and
well-sounding 12" woofer. The cone has an
aluminium frame for maximal stiffness and strong
magnet, but at the same time a low weight, which
contributes to the high efficiency.
To gain high power patience, we have chosen a
larger diameter on the coil. The driver is equipped
with rubber suspension for high strength, flexibility
and to gain a longer peak-to-peak excursion.
The diaphragm is one of the type "non pressed
papers" which gives a very stiff yet light driver. The
basket is founded in aluminium. This combination
of a powerful magnet, light driver and stable
suspension guaranty both enough power and high
precision in the sound.
