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

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

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. Its 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 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!

Even at a low volume youre 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

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
