Overview

12” driver

Cinema Performance with Maximum Impact

The Spirit SUB 12 is built around a custom-developed 12" long-stroke driver optimized for both home cinema impact and musical precision. Designed in-house by XTZ, the driver delivers deep, dynamic bass while maintaining accuracy and control.

Long-stroke pulp cone

A custom long-fiber cone provides ideal stiffness-to-weight ratio for fast response and low distortion, even at high excursion. Ensuring clear and undistorted playback, even under pressure.

High-performance motor system

A powerful magnet structure and 400W amplifier ensure linear motion and clean, distortion-free bass that stays controlled even at high volumes.

Engineered suspension

A ventilated spider and rubber surround support long-stroke movement without compression, while a high-temp voice coil and reinforced motor ensure control and impact under heavy load.

Class-D amplifier

Efficient power with low distortion

The Spirit SUB 12 uses a powerful and efficient Class-D amplifier derived from XTZ’s SUB 17 series, delivering high output with minimal heat.

Powerful output

200W RMS and 400W peak provide tight control over the woofer, combining cinematic slam with musical precision.

Low power consumption

The class-D technology in this amp draws less than 0.5 W in standby and only 12 W in idle, maximizing efficiency and minimizing wasted energy.

Exceptional Headroom

A specially developed PCB layout ensures clean clipping behavior, giving the amplifier high headroom and stability even during complex music or heavy bass effects.

Thick MDF cabinet

Rigid and acoustically inert

The cabinet plays a key role in bass precision. Spirit SUB 12 uses a thick MDF enclosure with substantial internal damping to minimize coloration.

Thick front baffle

A 25mm thick MDF front baffle and 18mm thick side walls, contributes significantly to its stability.

Minimized Resonances

Internal bracing and generous damping make the cabinet rigid and acoustically inert, minimizing resonance and allowing the driver to perform with precision and control.

Premium matte finish

Multi-layer lacquer in matte black or matte white blends into any space with a clean, furniture-grade look.

"With its sturdy and almost austere appearance XTZ gives a very solid impression. It is conveniently well built not too expensive and also sounding with a high entertainment factor. Actually there is nothing to complain on we surrender and give two solid Thumbs up! Although I liked the 95 series and although I call myself a reactionary I think the Spirit is a major step forward in the development for XTZ.- Thomas Odeltorp+ Well built and good concept+ Accurate and smooth sound- In this price range - nothing!"

"The new Spirit series is made for people who appreciate the true quality of music and movies. It is like real sound which gives you the feeling to really be in the center of the event. Gripping bass as well as accurate mid and treble are the strengths of the Spirit Series. The use of in-house developed and optimized high-quality drivers in neatly manufactured cabinets with a great finish is unique in this price range and even provides a larger number of audiences to enjoy the natural and balanced sound of XTZ speakers. -Zhuhai"

"XTZ has practically done everything right with the Spirit series: natural harmonious and precise sound noble workmanship contemporary look - and the whole at a price that amazes. For a around 2000 EUR it will be difficult to get an even more powerful overall package. The extremely powerful active subwoofers clearly stands out in the Spirit set. All components are well processed leaving little scope for criticism: It would be desirable if the Swedes offered suitable top firing modules for the Spirit 11 front loudspeakers.- Carsten Rampacher"

"For this price class XTZ offers a wonderful 5.1 set with the Spirit series which does not have to hide behind big names. The sound is full and powerful but at the same time also audibly dynamic. Specifically adapted to the own hearing or home cinema - The XTZ play a league higher than you would have expected it at the price and we say: Do not hesitate and simply try the set at your own home. - Erik Schober + Great price / performance ratio + Good sound reproduction + Numerous sound adjustments possible - Nothing"

"With the Spirit series XTZ has released a big hit. These loudspeakers look superb are first-class processed and even literally go through as sound furniture. Our 5.1 Surround Set from the Spirit line offers precise dynamic sound which meets even the most demanding requirements. A particularly practical feature is the possibility to operate all loudspeakers of the series as a bass reflex or closed construction in real listening rooms. Sound adjustment is also possible with the jumper on the backside lowering the tweeter level and the three presets of the subwoofer. A look at the more than fair overall price of the Spirit 5.1 set should also create a smile in the faces of potential buyers because with this performance and processing quality the set is an absolute purchase recommendation.- Michael Voigt"

"The fact that Scandinavians have a sense of good loudspeakers is nothing new that they love their home cinemas through long winters as well so no wonder the XTZ Spirit series is what it promises: high dynamics of discreet design with noble matt multi-layer finishes and impeccable processing. The whole Spirit set sounds pleasantly dynamic and shows rather warm earthy sound colors which will never be annoying and can lead to enormous reserves for its compact dimensions. Speakers like these are often only able to deliver either fine music or action-movies the XTZ Spirit series instead delivers both! ... This makes the XTZ Spirit series a real bargain.- Raphael Vogt+ Great workmanship compact size+ Variable sound tuning for all speakers+ Powerful subwoofer- Floorstanding speakers are little unsteady without optional feet"

"The XTZ Spirit Sub 12 is able to convince in every discipline. Stylish optics high-quality workmanship rich equipment for great flexibility and a powerful yet precise sound are the characteristics of the Swedish subwoofer. Weaknesses are looked for in vain. The competitors are also strong but the XTZ impresses with its high acoustic harmony and the absolutely identical handling of music and movie source material. Very high SPL capabilities and an outstanding precision even with parallel occuring bass effects are part of the impressive performance. This is how to build active subwoofers: the XTZ Spirit Sub 12 combines enormous performance and high-quality appearance for a small purchase price- Carsten Rampacher"

"The idea of the Spirit Sub 12 is very powerful can be characterized by a very precise punch and the timing is excellent. The reproduction is never exaggerated and makes a perfectly dosed impression. When the events in the movie are getting really violent like on the UHD by Hacksaw Ridge the XTZ subwoofer really shows what it is made of.- Matthias Fengler+ first-class workmanship+ high-quality sanding varnish+ Low frequency range+ Customization options- Sockets for front cover visible"
