Technical presentation
Cabinet design
The cabinet is very lavishly fitted out and made of 25 mm MDF.
It is equipped with a specially modelled bass reflex gateway to
avoid blowing noice and to decrease the air resistance in the
gateway.
We have chosen 25 mm MDF to have a low own resonance. The
cabinet is built with bars to make it even more stable.
The woofer
driver
The XTZ W12S is equipped with a powerful and well-sounding
12" woofer. The cone has an aluminium frame for maximal
stiffness and has at the same time a low weight, which
contributes to the high efficiency. Also the powerful magnet
contributes to this.
To gain a 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 paper" 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 makes up for both enough power and
high precision in the sound.
The amplifier /
crossover
We have equipped the XTZ W12S with a very powerful amplifier
on 400 W and a big cooling flange for effective cooling. For
professional (studio, PA etc) use, 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 amplifier.
The active amplifier also provides a variety of possible
adjustment possibilities, unable to obtain using a passive filter.
This includes phase, frequency, high pass filtering, volume etc.
By using these settings, the main amplifier is relieved and thus
only takes care of the midrange and trebble. Thus it works
better and the risk of damages on it is lowered.
