"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

"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

"Low price with great sound - these are the XTZ Spirit 11. At first glance somewhat unspectacular, as the treble sounds more clean than agressive, they show, especially at higher volume, a great performance. With a proper punch in the bass and a neutral overall tuning, the Spirit 11 is suitable for audiophile leisure as well as for big home cinema thunderstorms."
- Torsten Pless

"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 XTZ Headphone Divine, the Swedes make an impressive debut in the headphone segment, comfortable to carry and uncomplicated in handling, the Divine is a good companion for its sensitivity and the low impedance of low-power amps from smartphone and co. While its balanced sound image does not have any weaknesses but scores with long-term suitability and agile suppleness."
- Fritz I. Schwertfeger

"The Tune 4 is particularly impressive for its price class of around 500 euros, which is mainly due to its transparency, structure and high-quality precision. Tune 4 rewards the listener with a bony-dry, precise bass, and thus expresses the emotional expressive power of even the most demanding music impressively." "At the same time our team awarded the XTZ Tune 4 as a sound reference in the active box price class below 500 €."
- Gerd Büsse

"The Spirit speakers have embraced high technology, and they are your best choice if you prefer a powerful and balanced sound experience. Indeed, your demand would be available by the different ways of speakers matching." "When appreciating the movies, I select another blue-ray disc of Celion Dion Las Vegas Concert to review the reproduction of the Spirit Series in s multichannel setup. What surprises me is that it leaves me a so incredible impression that I feel surrounded amongst the rhythm performed by drums and the clear and accurate high-pitched voice of Celion Dion!"

"With a clear, precise bass reproduction which can be modified by the wide range of possible settings between particularly deep and structured-dry sound, the subwoofer inspires its listeners. This allows the discerning user to adapt the sound perfectly to his / her personal preferences as well as the conditions of the listening room. The Sub 8.17 presents itself as an excellent bass loudspeaker, which is perfectly suitable for the sound support of compact boxes and can be considered almost as a bargain for the price of 345 euros (plus shipping). XTZ has without doubt landed a perfect hit with this subwoofer."
- Gerd Büsse

"The XTZ speaker therefore marks its place in the dance of the top speakers, which are still affordable. Practically nowhere is there more box for money - first-class housing, highly solid, brutally heavy, elaborately braced and pattern-processed. In addition there are drivers of well-known manufacturers, which offer reference level without compromises. The Divine Alpha, with its two qualities, is very exciting: Emotional-deep acoustic harmony and a sovereignty, which we rarely experienced in 20 years of test experience."
- Carsten Rampacher

"The Spirit 11 doesn't sound or look like a beginners speaker at all. The processing is very high-quality, the massive cabinet is equipped with an excellent varnish finish and is very valuable. The Spirit 11 delivers a rich, dynamic sound, and has also been harmoniously tuned."
- Matthias Fengler

+ Valuable processing / lacquer finish
+ Technical equipment
+ Customizable sound
+ Sound characteristics / tonality
+ Allrounder music / film operation
- Bracket for front cover optically not solved optimally

"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 2,000 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

"A versatile and well built pair of bookshelf speakers, the budget for which if you have, there is no where else you should put your money." "We have hardly anything to complain about here. If there has to be pointer, it would be the 99.25's disagreeable nature with MP3s. You make that mistake and the XTZs don't forgive you for your bad judgement. Feed these only the best you have to offer and enjoy a sound that's well rounded and balanced. These are speakers best enjoyed with a nice glass of whatever poison you like and a playlist that won't end."
- Kaizad Billimoria

+ Superb balance, detailed midrange, airy treble, tight bass
- You just get two for that price, we want more

"XTZ Spirit 11 plays well above expectations, and marks a new level of quality in the price range below 8.000 NOK. They sound entertaining and engaging and together with a reasonable amplifier you are only one purchase away from an amazing listening experience. Suddenly XTZ was the reason why all the other manufacturers of speakers must sharpen up yet little extra, get up very early in the morning and come up with new stuff that plays even better. They also did well, but right now I can not see others who completely manage to compete with Spirit 11 at this price."
- Håvard Holmedal

"Even at a low volume, you're almost in the middle of the action, and the basic design of the Tune 4 is also very good at low volume, with a warm and precise bass. It is a very pleasant and unobtrusive sound picture, which is further refined and optimized with the DSP settings "On Wall" or "On Desk". Then the software can be used to slow down the bass or to modify the run times for the table reflection, which can definitely be heard and the difference is impressive."
- Maik Dahles

"Given the SUB 1X12’s hulking presence, I couldn’t resist cueing up a few favorite bass cows. The opening of Hall & Oates’ classic “She’s Gone” bloomed with 30-Hz deliciousness, while the finale of the Saint-Saëns Organ Symphony was in-the-hall awesome, and my few, in-the-name-of-science dub-step tracks indeed proved a dentist’s best friend. 

Even at reference level in my substantial-volume studio, the XTZ sub had no problem presenting Max’s most impressive impacts and explosions (of which there are many) with full effect and nary a trace of limiting or overreach."
- Daniel Kumin

"The XTZ offer a perfect performance in almost all criteria, but their greatest talent is that they reproduce music wonderfully homogeneously. The clean reproduction of sound colours, which clearly shows every instrument, intertwines with high localization, resulting in a tremendously authentic overall impression. Similar synergies arise from tonal neutrality and resolution. Both - in each case to a large extent - do not sound cool or analytical, but simply correct."
- Martin Mertens

"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!

"As usual, I started listening to heavy psychedelic trance music and directly got a mild shock over the high sound pressure which these small speakers can deliver. Reverberation is dark and the bass performance really impressive. Placed on a desk in a not too large room, the Tune 4 provide lots of joy and energy."
- Johan Ahlström, Hifi & Musik nr 12/2016

"Tune 4 is a premium speaker for sophisticated demands. Thus they play very natural and detailed what is very convincing especially when playing challenging music. They are not effect-speakers which try to convince by an exaggerated bass level. It is perfect for users who value detailes and balanced sound."
- Michael Barton

"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

"With Tune 4, XTZ has really presented a powerful speaker in the compact speaker class. For the price you can build a small, fine high-end system, which can grow with increasing demands. Do not forget: The amplifier electronics is already included in the price. There is also a wide range of possible applications. It's just like a product of the now time from Cupertino, California. And as already described, like an espresso: small, strong and black - refreshing and rich in content."
- Andreas Limbach

"The ultimate test for new speakers or headphones is usualliy if i get excited to go through my muisc library again and listen through every track with the new equpiment. This emerged fully when i listen to the TUNE 4 speakers, which shows the high quality of the speakers."
-Jakob Nilsson, 99mac

+ Flexible format, easy to place
+ Lots of inputs
+ Great sound
- No support for Airplay or Spotify Connect
- Simple app

"The XTZ Tune 4 is an excellent compact and powerful speaker for music lovers." The Tune 4 is a versatile loudspeaker for all hifi applications, despite the slight reductions in the possible connections (Wi-Fi application, USB, remote control). "
-Benoît Campion

+ Warm, musical sound
+ Wide sound stage
+ Compact and powerful
+ Solid construction
+ Many connections for a stereo speaker
- slight distortion at high volume
- preferred good recording
- slightly tippy
- Remote control a little too small

"Even without DSP support the Headphone Divine sounds absolutely convincing. Neutral without the popular bass boost, it provides a pleasantly balanced, transparent sound that has a lot to offer in terms of fine detail and dynamics. Whether actively driven via Bluetooth or passively via cable the headphone does a great job. With the DSP the sound is even better. "
- Martin Mertens

"XTZ speakers have a surprisingly rich bass for such small elements. They sound definitely bigger than they look, and electronic pop music rhythms have good fullness and weight. "
- Lasse Svendsen
