( Stock Clearance ) XTZ Cinema SUB 3X12 – Matte Black

The 12″ Bass driver of the Cinema Series is called advanced High-Speed Ultra-Long-Stroke  with the use of a very light cone material and a very strong motor (magnet) structure.  We choose fast and light drivers to give both high speed and maximum dynamic sound. The bass drivers are able to perform the ultra-long strokes with a maximum of linearity and we also developed a special NBR (Nitrile Butadiene Rubber) surround to complement them. The requirements of the drivers mean that to achieve the highest SPL even down to the lowest frequencies the boxes need to be big. This is just pure physics. An optimized volume for the driver gives the perfect air resistance to the driver. This leads to the highest SPL in low frequencies with maximum head room from the amp. Boxes that are too small or too big  lead to over damped or underdamped subwoofers that have increased distortion. A box with an optimal volume has low distortion and the widest frequency response possible enabling the subwoofer to deliver the lowest and deepest bass with a sound that is still clean yet has a lot of headroom for the amplification. We required our subwoofer to provide very high sound pressure levels yet remain precise and true to the original music.  We met this challenge by using the specially developed low-mass long throw driver. The 12” cone consists of a very strong, long fiber pulp blended material optimizing the diaphragm’s stiffness to weight ratio. Our custom designed drivers have several more advantages to achieve the perfect bass:

• FEA Optimized magnetic field design incorporating a tightly focused “T” pole design;
• Advanced level of large signal motor and suspension refinement using a KLIPPEL laser-based test system;
• Large aluminum shorting ring to minimize inductance and further lower non-linear distortion;
• Ultra-high temp aluminum voice coil with Airflow Maximizer Design;
• Special NBR rubber surround with maximum linearity throughout its excursion range;
• Spider fabricated from a unique blend of poly-cotton and pure NOMEX

This completely new amplifier, specifically developed for the Cinema subwoofers, has an extraordinarily high power output of 500W RMS and 900W in peak wattage whenever it is needed. The Cinema SUB 3X12 uses one Claridy mono-block for each driver for a total of 1500 W RMS / 2700 W Peak. Class D amplifiers work in a different way than A, B, or A/B amplifiers. Since Class D (“switching”) amplifiers can turn fully on or off, they can dramatically increase the mid and bass output power while minimizing the loss of power, making for a highly efficient amplifier that is very suitable for subwoofers. It eliminates the need for huge power transformers, banks of output transistors, and huge extruded aluminum heat-sinks. Class D amplifiers are remarkably compact for the amount of power they produce. The technology is very effective and a good illustration of the efficiency of Class D amplification is to imagine a chip-sized module that is 3” wide, 5” deep and just 1.5” in height, producing up to 500 W all while delivering 90% of the power it receives to the loudspeakers.  Class D technology is also environmentally friendly due to its energy efficiency. In the past, most Class D amplifiers had a lot of distortion challenges but not anymore. By using state-of-the-art Claridy Class D amp technology with near ideal clipping characteristics, we ensure maximum headroom capability by minimizing the use of limiting circuitry. This results in a precise sound that is noise and distortion free and a never before experienced amount of detail. These achievements and the amplifier’s powerful performance are the result of the many years XTZ has invested in perfecting the design.

To provide optimal sound quality adapted to various room sizes and listener tastes, the SUB 3X12 offers many tuning options for sound adjustment. Since the SUB 3X12 has its -3dB point at a very deep 16Hz, we decided to add a special Room Gain EQ that takes the room gain into account. Additional adjustments can be done by closing the slot bass port with the provided plug. So the 3X12 offers perfect bass for any home cinema environment. Further refinements can be made by adjusting the volume, phase, and crossover frequency.
