SUB 12.17




XTZ is well-known by both media and consumers for making subwoofers that perform way above its price tag and the new SUB .17 Series raises the bar even higher. The XTZ Subs have always had a good balance between deep powerful bass response and rapid mid bass in a compact size. Making it suitable for both home cinema and music setups. The wide range of adjustments have also made it very flexible and easy to tune for any room. SUB .17 promises to go deeper and play faster than ever before.

SUB .17 Series Features


- Long stroke / high speed driver 
- High sound pressure level for its size 
- High efficiency class D amplifier optimized for low   distortion & excellent sound quality   
- Stable cabinet, reinforced with thick bars 
- Room tuning for adaptation to different rooms
- 3 EQ settings
- 4 bass characters
- Selectable bass reflex or sealed construction 
- XLR Balanced input/Direct Pass-thru

Cabinet Construction


SUB .17 uses a cabinet construction made out of thick 25 mm MDF which is further reinforced by using internal bars for maximum stability. This helps to achieve the lowest level of internal resonance. The outside is covered with high quality paint to give you a first grade finish.

High speed Bass driver



XTZ call this a low-mass, long throw driver “high speed” because they use a very light and stiff cone material and a very strong motor (magnet) structure which provides an incredibly fast driver. It can produce amazing sound pressure levels with great dynamics and yet remain precise and true to the original music. The team spent years finding the perfect cone material since the combination of weight and stiffness is one of the most critical factors in a driver construction. The material they found which managed to meet all requirements is made out of a very strong, long fiber pulp blend. The cone was also fitted with NBR (Nitrile Butadiene Rubber) surround to be able to make the necessary ultra-long strokes needed to meet their high requirements on sound pressure.

Class-D Amplifier



SUB .17 uses the modern and effective Class-D amplifier. It has an extraordinary high power output for the driver with almost 2 times that in peak wattage output whenever it is needed. The amp is the result of years of design refinements and ensures an unprecedented amount of details and maximum performance. 

Digital Signal Processing

This amp features an advanced DSP processor. Our DSP gives the amp unmatched control over the driver at all levels with two EQ settings so it can be optimized for your taste with a more refined behaviour.

Room tuning



Choose between sealed or ported design

The bass character can be altered by plugging the reflex ports of the subwoofer with the included foam bungs. Even further optimization can be made by 2 EQ settings and of course by adjusting the phase, crossover frequency and volume.
