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!

12.17 is a large and extremely strong Subwoofer! Besides this subwoofer even my speakers look small. In any case a purchase recommendation! This subwoofer plays down to 19 Hz which means you cannot only hear the deep bass but also feel it very strongly! Movies are now much more realistic when everything shakes :) Not recommended if you live in a rented apartment with fussy neighbours. The box is huge thus unwieldy and the subwoofer is really heavy. Purchase one and have fun: D

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

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.

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.

The XTZ 12.17 was acquired in exchange for a JBL ES250P since it began to whistle. The shipping was really fast! The sub can be very well fine tuned unlike my JBL which sounded already very good. I especially liked the possibilities to change the sound by using the bass reflex plugs. So I use the 12.17 in closed mode since I love that precision and still have a lot of deep bass. The optics has also convinced me 100%: I love the design and also the excellent finish! Just one thing: The front cover was very hard to mount the first time so I first thought there was something wrong with it. The XTZ service told me that it was hard to mount depending on temperature and humidity the first time. This is true it is much easier later on. Great product!

The sound of the XTZ 12.17 is excellent. Wonderful bass at its best! No jingle buzz or rattle. There are many possible adjustments but still they are very easy to handle. In addition to the rich bass sound we also liked the auto on/off function. Summarized the sub has an excellent finish and the sound is just pure enjoyment. We would buy it again! Therefore we can all only highly recommend the 12.17.

The 12.17 creates a great bass performance in my living room (40sqm). Before that XTZ woofer I had a woofer from Harmann Kardon but the XTZ is much more powerfull and also precise. It is also easier to integrate the 12.17 into a surround system harmonically. I put the crosssover frequency at ma AV receiver to 80Hz and at the subwoofer used the bypass of the own crossover. I use the EQ 2 to have a little more punchy bass which I really appreciate.

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 :)
