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

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

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.

And as already described like an espresso: small strong and black - refreshing and rich in content.- Andreas Limbach
