What to say....Exellent finitures great sound so happy of my purchase. Thanks XTZ

For a long time I hesitated with buying but after a comparison with a SVS PB2000 I purchased your 12.17 and never regretted this decision. Among my friends not a single one could understand why someone spends so much money for a subwoofer. After all you can basically get a whole home cinema system in the well known electonic-markets for that amount. That opinion changed after an invitation to listen to the sub -). In the end the most important thing is to be happy with the decision and that is definitely the case for me. For me as a resident of a block of apartment this woofer is more than enough but the deep clear and precise sound of the woofer makes me happy ervery time. I recommend everyone not just to rely on reviews or reports but to test the subwoofer in your home. Howevery I can highly recommend the 12.17!

Really a good and powerful subwoofer with good workmanship. The bass power is almost too much for a rental apartment with normal roomsize (20-30qm). For the price of 645 € an absolute purchase recommendation.

I consulted by a friend to add another sub to my home theater which at that time was bass-powered by Finnish Amphion Impact 500. So I did and I was amazed how well low frequencies were produced in my small home theater! It was a good combination but something was bothering me and I thought it might be due to two non-identical Subs! So I leveraged XTZs superb Buy&Try option and placed the order for another 12.17 :) And YES now its as good as I (and my friends) can imagine. I truly can recommend XTZ 12.17 (not to mention the affordable price tag!). And pls keep in mind: two subs are sooo much better - even in a small HT like I have :)

My old Subwoofer Teufel from the Theater 3 Series (M3100) has unfortunately once again broken and I was tired to send it in again for repair because I was never really happy with it. Somehow I always felt the sound to be unprecise and muffled. So I ordered the 12.17. After calibration with the Audyssey mic and manual readjustment Im finally satisfied with the sound of my system. An accurate and dry bass. However it took me a while to play around with the settings of my Denon AV Receiver and also shut off the dynamic equalizer because the bass initially quite boomed. Now the subwoofer makes listening to music a real joy and movies have a perfect cinema sound. Congrats XTZ!

Large black and powerful! Actually theres not much more to say about my 12.17. I operate the subwoofer with a Yamaha Receiver which is a good combination. Super price / performance ratio! Highly recommended!

I firstly ordered the Canton AS 85.2 SC active subwoofer (200/250 Watt) because it had very good reviews and ratings in all tests. Unfortunately I was very disappointed with the Canton. It began to chatter at mid SPL and basses were partly very soft and not precise. So I decided to order the 10.17. That sub really has a very good transient response maximum bass high dynamics it plays rock / metal with rich bass as well as drum and bass techno minimal etc. Even with acoustic singer/songwriter the bass is never intrusive. I am more than satisfied. Clear purchase recommendation for ambitious amateur music listeners.

The 12.17 is a very good subwoofer which creates a high sound pressure and plays really precise. I mostly listen to music and use it for studio purpose. In combination with my studio monitors it creates a really flat and neutral frequency response. It was very easy to install and fits great with my monitors. I would have loved to have access to the inner DSP of the subwoofer which seems to do a really good job. Maybe that is possible in the future Otherwise a really great subwoofer.

A great and very powerful subwoofer. The bass is accurately reproduced. Fits great with my stereo system with two large floor standing speakers. The 12.17 is perfect as addition for movies to provide the deepest bass which the floorstanders cannot provide.

It took me a long time to think about what a subwoofer I want to get me and only after a long search I had the idea to look look at the XTZ subs. What can I say ... I was not disappointed. The sub is mainly used for movies and series but I also use it to play techno and other sub-genres of electronic music. The bass is precise and accurate. The Auto-On / Off works fine and he makes me happy every day. I would buy it again in any case
