Recommendation - Award Score: 8.8/10 A well-designed properly manufactured and reasonably priced subwoofer. The SUB 12.17 is able to do everything a good sub should do. It has a massive and sturdy housing a powerful driver and amplifier and a lot of adjustment options - both electronic and acoustic. Using the settings you can tune the subwoofer to every speaker. XTZ can enrich our music gently pulsating in the background and adding a concert depth to it but with a touch of a switch it can also become a real beast shaking the walls when youre watching a movie. All things considered I think it will be a difficult task to find a better subwoofer at this price.- Tomasz Karasinski StereoLife Magazine

Likes - Award At the risk of being repetitive I must pay tribute to XTZs latest bass creation even without taking the price aspect into consideration. Were offered quality subwoofers performance all the way down into the sub-contraoctave the adjustment possibilities for both room and taste and power enough to shake any bigger normal home cinema. But this isnt all the price places SUB 12.17 in its totally own niche and it doesnt even put it self to shame against twice as expensive competitors. In its price range XTZ SUB 12.17 is totally alone to perform full grown bass in this way and to be totally clear. We think SUB 12:17 is awesome!- Jonas Bryngelsson HemmaBio Tidningen

Reference -Award Score: 9/10 XTZ have established a new reference at affordable price. I have never before seen such a quality level at this price level. sublime and devastating bass. Low pitched response goes deep strong and quick precise perfectly readable over a large frequency range and adds a lot to the emotions that one could feel watching a movie or listening to music. Talking of the quality of XTZ bass is talking about musicality really. A true and complete success- Nicolas Bécuwe HDfever

With the 12.17 XTZ releases one more enormously powerful subwoofer which provides first a superior price / performance ratio and which in this price range particularly with regard to its manufacturing quality and also its acoustical properties should be emulated.- Philipp Kind AREA DVD+ Excellent price / performance ratio+ Very good finish+ Integrated Equalizers+ Enclosed plugs for the bassreflex tubes+ Outstanding acoustical properties

Pure fun then in Mad Max: Fury Road and Mission Impossible: Rogue Nation where the subwoofer can dish out uninhibited and shows why a bass specialist is vitally important for home cinemas. The 12.17 reaches highest sound pressure levels without even flinching. The bass waves are sweeping through our listening room the deep bass energy can be felt in the whole body. Here again it is very impressive with which precision the XTZ subwoofer is working.- Dirk Weyel HiFi Vision

In conclusion there is no question we have two subwoofers I really like. The construction the upstream design of the speakers and all the possibilities offered by the DSP and amplifier are remarkable. You better keep an eye on this brand that knows what they want and know how to get it. The price of the two subwoofers are very tempting and if XTZ continues with this policy you will hear a lot more about them. - Gian Piero Matarazzo

Far from it the floorstand speakers are giving even for acoustically most demanding material their best and convince with precise timing wonderful balance and excellent fine dynamics. The Multi-channel system of 99.36 99.25 and Sub 12.17 continues this virtues and so present different artists like Metallica ( Through the Never ) or Adele ( Live at the Royal Albert Hall ) perfectly. - Jochen Schmitt

The XTZ subwoofer line-up is a tough competition to other subwoofers. The Sub 12.17 is one of the more compact and cheaper subwoofers compared in this test but offers the same high sound pressure level and outstanding sound quality. When it comes to the quality of the components and finish other manufacturers have a disadvantage compared to XTZ. Try and buy the best subwoofers of the comparison test.-Audun Hage+ Precise+ Musical+ Natural- Nothing

The SUB 12.17 is another great subwoofer from Swedish manufacturer XTZ. It utilises a 12 driver and Class D amplifier combination that is based on the design the company uses in their award-winning Cinema Series.- Steve Withers + Superb performance+ Flexible setup+ Excellent build quality+ Great price- More power in the amps would be nice
