Superb! Best bass I have ever heard in this pricerange! Goes so low i just need to sit down and feel those goosebumps crawling all over my back! Love it!

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

I have got this sub for a few months now. The room is over 25 square meters with a small kitchen and a hall (40 square meters counted together) so there is some place to move air. SUB12.17 plays in a 5.2 configuration. System is based on Polish loudspeakers (Pylon Audio Diamond series) Yamaha (center and back) and NAD (front) amplifiers and there is already one another subwoofer: Paradigm Seismic. The Paradigm is a little beast with a very small closed casing. But its really powerful Seismic its not only an advertisement. So the surrounding components are good quality. For now I have LFE signal through front speakers (they have very nice low end) and both subs. I had a bit of work to set subwoofers in the room because of interference but its nothing special regarding a bit complicated system. When I compare Paradigm and XTZ both devices produces nearly same quality of bass despite of absolutely different solutions (closed vs vented). XTZ is really fast not muddy also when REF is selected. Of course it goes really deep. For music I prefer REF but for movies EQ2 with a bit of additional punch just sounds better to me. What is really outstanding XTZ has more tweaking options - standard vol phase cutoff knobs eq presets and tuned vents. Movies and concerts are different some of them with deep and loud bass line and some quite weak-sounding and thats when XTZ comes in - fast switching or vents tuning and youre on the way. XTZ sub is really well made details are outstanding (nice gloves feels premium) and it sounds really good. I have to add that the manual is helpful setup is easier especially when you try to use EQ and vented ports.

very satisfied with my purchase. I had to fine tune the xtz sub 12.17 edge a bit but then the result is great too. it is certainly suitable for music listeners but I would close the ports. then the bass tones are dry and tight. this sub can certainly go with the best but the price is a lot friendlier. the quality is very high. contacting is also easy and to your liking for questions and support

I can only agree with the previous reviews. After being a very happy owner of the standard Sub 12.17 I had some unfortunate issues with the built-in amplifier. No worries! XTZs fantastic customer support not only helped despite me having since relocated to the other side of the world. When sending a replacement they also offered an EDGE upgrade. This made my subwoofer perform at levels I didnt think were possible at this price range. I can honestly say that the 100 euro price difference for the Sub 12.17 EDGE is worth every cent. Extremely refined clean bass with a nice punch that can be felt. For anyone looking for a new subwoofer I can give this speaker my warmest recommendations.

Due to my small room i never had the opportunity to find the optimal spot for the subwoofer so it didnt sound well it was very boomy and lately the subwoofer was producing some noises so i thinked it was upgrade time! After many research and very good feedback of the SUB 17 series due to their sound quality and the room tuning options with a very affordable price i went in contact with XTZ Support asking them an advice because i was undecided between the 10.17 edge and 12.17 edge subwoofers. Mr. Olle advice me to go to the bigger model so i bought 2 due to the benefits of using more than one subwoofer. What to say about them.... simply they are amazing they are very fast and produce a very clean tight bass with an unbelievable strenght that i feel on my backs which is very pleasant all the problems i had with the bass are gone.

What a wonderful Subwoofer and company! After reading many positive reviews in internet I decided to buy a XTZ 12.17 Subwoofer. I contacted to company for purchase and they upgraded my sub to edge version which is even more powerful than the original one. Last week I watched a film with my friends. Everybody liked the sub. Its located in my living room which is more than 30m2 and I didnt feel any power issues! We were all shaken! You cant buy anything close to it for the same price. And Its not just about price or power...its about versatility its about quality its about customer service. If you think that you can buy another subwoofer for the same price think twice! It will have one option but not all together. A high end amp... or three color options...or sound tuning options...or higher build quality...or such a long warranty... Its really an all in one subwoofer. There is no match in its price category and well above!
