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.

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!

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!

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 :)

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.

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!

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