...after its well burn-in it shows its wide sound field clear and soft sound not emphazing quantity of the low frequency but persuing the detail quality. Compared with Grado RS-1 headset EarPhone-12 presents a plain and calm trend and if compared with Etymotic ER-4P monitor earphone it shows more elegant and mild. - Huang Guoxuan PrimeAV

Score: 5/5 The sound out of the box was pretty damn good for an earphone in this price range but when I installed the XTZ Player and turned on the Dirac DSP correction Just WOW. The soundstage opened way up the clarity in the bass and highs improved greatly and it just put a smile on my face.- Mr_Owlow Head-fi.org

Performance way above its price range ...here we have the speaker bargin of the year! 100 percent home run- Magnus Fredholm Hemmabio

Score: 9/10 The sound out of the box was pretty damn good for an earphone in this price range but when I installed the XTZ Player and turned on the Dirac DSP correction I was blown away. The soundstage opened way up the clarity in the bass and highs improved greatly.- Luke Thomas droidhorizon

Score: 5/5 Value: 5/5 Product of the Year Award The XTZ Cinema Series 3X12 subwoofer is one of the most powerful subwoofers weve ever tested. It proved to be unflappable no matter what source material I threw at it or torture test I had it endure. This is a serious bass system at a very down to earth price. ...a killer deal...- Josh Ricci Audioholics

Never once did I hear the SUB3X12 make an untoward noise no port chuffing no complaints from the drivers no audible distortion no abnormal sounds. As capable as the SUB3X12 proved to be the speakers actually stole the show and boy did they ever play their part beautifully. This is a different level of detail here folks. So revealing - and flat out pleasant sounding - was this system that I spent far more time enjoying music than I did anything else. Its a rare treat for me to hear sound reproduced at this level... The XTZ Cinema Series is a sonic tour de force a complete system that encourages you to dig deep into your movie and music collection to unearth hidden gems long since forgotten. Why Because now you will want to experience everything in your library all over again. The SUB3X12 is a beast and can certainly hold its own but for me the real stars of this show were the speakers. I honestly cant think of a single legitimate complaint about the M6 mains or S5 surrounds and with how picky I am thats saying quite a lot. If you want a system that will simultaneously get your friends tongues wagging and their jaws dropping then XTZ Sound has something you need to hear- Jim Wilson Home Theater Shack

Score: 6/6 Particularly Reccommended Award ...here we simply end up in a class which is far above its price... Price/quality is simply Outstanding! - Sven Bilén Ljud & Bild

Score: 4.5/5 Excellent sound light fairly priced excellent company 60 days money back guarantee ... I have tested a LOT of BT headphones and I can tell you will NOT find this level of sound quality if not on very few BT Headphones which cost twice or thrice as much.- Giogio Head-fi.org

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

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
