The SUB 3X12 uses three 12" High-Speed Ultra-Long-Stroke drivers engineered for extreme dynamics and control. Each cone is constructed from long-fiber pulp reinforced with polymer and paired with a high-strength motor optimized for deep excursion and low distortion.
Custom-designed high-output drivers
Long-fiber pulp cones with polymer reinforcement and dual pole design for speed and strength.
Motor and suspension optimized for control
Massive motor structure, aluminum shorting rings, and KLIPPEL-refined suspension deliver low distortion and tight tracking.
Triple-driver configuration
Three drivers share the load for higher SPL with reduced distortion and improved thermal handling.
Each driver in the SUB 3X12 is powered by a dedicated 500 W RMS (900 W peak) Claridy™ Class-D amplifier, that are linked to delivering a combined 1500 W RMS and 2700 W peak. These amps use near-ideal clipping behavior for maximum headroom and reliability under demanding conditions.

Ensures precise control and consistent output from each woofer.
Class-D design with thermal protection
High efficiency with advanced thermal and overload safeguards.
Designed for cinema-grade headroom
Maintains low distortion and full dynamics even under heavy load.
Whether you're integrating into a home cinema or a stereo setup, the Cinema SUB 3X12 provides multiple tools to shape bass response. These include two EQ profiles and port tuning. Together, they allow you to adapt the subwoofer’s performance to your room acoustics, speaker setup, and personal preference.
SUB 3X12 offers precise control over its infrasonic performance.
The SUB 3X12 can be used in sealed or reflex operation. This lets you tailor extension, decay, and output based on room size and listening goals.
Room Gain and Anechoic filters
Room Gain compensates for boundary gain in smaller rooms, while Anechoic preserves the full 16 Hz extension for large spaces or advanced correction.
Port open
Max extension and SPL with increased low-end output.
Port plugged
Tighter, more controlled bass with earlier roll-off and sealed-box behavior.
The SUB 3X12 is housed in a heavily braced cabinet designed to handle the extreme forces of three high-output drivers. Its trapezoidal shape reduces standing waves, while thick MDF panels and multi-layer damping minimize resonance.
Reinforced cabinet structure
25 mm MDF walls with 55 mm thick front and base, plus 40 mm bracing for high rigidity.
Internally damped and insulated
Multiple layers of insulation and internal baffling reduce unwanted resonance.
Finished for visual discretion
Matte black anti-reflective lacquer and Nextel-coated side panels blend into dark cinema rooms.
"Price range - Reference - Award First-class ultra-solid and loud playing active subwoofer for a very reasonable price The performance from most competitors seems like a gentle breeze in comparison at best. The sheer force offered by the Swede is really impressive and shakes all the way down to the very foundation of listening room. Everything that gets thrown at the SUB 3X12 is handled with ease without breaking a sweat. This is because each chassis has its own power amplifier so there is no performance degradation even under heavy loads.- Carsten Rampacher AREA DVD"
"A real success from XTZ and we give the SUB 3X12 our warmest recommendations! - Magnus Fredholm Hemmabio"
"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"

"Highly Recommended - Award Overall when assessing the sound quality and how well these XTZ Cinema Series speakers work together I am struggling to think of any negatives at all. The sheer soundscape they are capable of producing and the way they are so well matched to create a cohesive soundstage that just melts away and does so on a few levels makes you wonder why you would want the new 3D sound formats. There are a few occasions when you just hear a well put together speaker and sound system and things makes sense and you are transported away without noticing. That is what the XTZs were capable of doing for me in my system and it was the cohesive nature of the performance that nailed it for me. They go loud they are dynamic and they can get in your face when required. - Phil Hinton AVForums"
"Phenomenal - Award Strong performance from Sweden! The XTZ Cinema 5.1 set can be noticed very positively in the home theater operation. Closed soundscape lively effects high SPL and tremendously strong bass performance by the world-class active subwoofer are offered. In music mode the services are very respectable the total harmony could only be a little bit higher. The high-quality finish and the and sophisticated technology are highly commendable. For the offered price is fair no doubt. - Carsten Rampacher AreaDVD+ Closed densely atmospheric sound thanks dipoles+ Very high SPL+ Extremely powerful active subwoofer with no weaknesses+ Uniform clean staggered front soundscape+ Subwoofer with two EQ modes for appropriate adaptation to space+ Very good separation of all sound elements from the speakers+ Fair price- In music the overall harmony could be a little bit higher- Optik not for everyone"

"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"

"The best thing the XTZ loudspeakers do is to disappear and never remind you that youare listening to loudspeakers. Youll find music and movies both havea natural sound with an ease of presentation that makes the presentation live in your room.

"Editors Choice - Award Very evocative sound intelligence of this system wrapped with slick design integration which is well proven in delivering several different sonic aspects Its the reason why we are in urge to review it immediately. - WHAT HI-FI"
"Score: 5/5 The XTZ multichannel system convinced by its unusual design excellent workmanship and most importantly - excellent sound in a home cinema environment. The asked selling price is extremely fair which is why we want to give our Preistipp logo. - Jochen Schmitt hifitest.de"
"You can probably tell Im in love with this system. If you think Ive got carried away I can only suggest you have a listen yourself. At this price few speakers emulate the feeling of sonic immersion quite like the XTZ. The additional Atmosphere speakers make the array a good match for modern setup. 5.1 fans shouldnt ignore the core models either. We say: A superior-sounding movie-mad speaker system offering seriious value for money. Plenty of installation flexibility and solid construction. Not the prettiest of cabinets.- Danny Phillips"
"While Ive saved it for the end I did notice that the XTZ setup is at nearly $5500 expensive. XTZ sells direct to consumer though and with a generous home-trial period free return shipping and the Cinema series quality of componentry construction and performance theres value here nonetheless. Cost aside XTZs Cinema is a very impressive home theater setup. I cant see recommending it for a music-first layout but I doubt that most such system- builders would be interested anywaythough this Swedish layout is still a very able music reproducer. For a serious projection room install based on an acoustically transparent screen a genre that tends to be fairly price-insensitive anyway I think this system is just about ideal.- Daniel Kumin+ Very dynamically capable with high power handling high output+ Solidly integrated front stage+ Impressive subwoofer output and extension+ Flexible tripole surround speakers- Slightly forward tonal balance (but perfect for behind-screen placement)- Pricey"
5 / 5
The 3X12 is just wow. Whenever I really push the volume to the max I fear that my house is beeing damaged by this powerfull subwoofer. But it is not only the max SPL that is astonishing it is also how smooth the sub is playing. It never seems to reach any limit and always stays precise. I even use it for music playback since it is a perfect complement for my floorstanding speakers. Great job guys!
I purchased the 3X12 to reproduce subsonic sounds with maximum SPL- the 3X12 perfectly fulfills this task. It accomplishes challenging SPL orgies in my home theater and in comparison to the SVS PB 13 Ultra which I had before it also plays very precise. The 3 X12 is a top model in home cinema for low bass lovers! It lets pant legs flapping and rocking the bed - and sometimes even without you hear it ) I recommend some space in the home cinema where the 3X12 is used in. Otherwise I do not see any alternative in that price range!
Great subs im sure you wont be disappointed! Im running them with a pair of PMC BB5is with a pair of Bryston 14BSST2s crossovers in the pre amp so passing through the 3 x12s back into the bass side of the Brystons. After setup I did a final tweek with Lyngdorf RoomPerfect and the results are great. Im in a reasonably large room at 7m x 10m and lots of glass which can be a bit bass lossy also a suspended floor which can reverb a bit but everything comes together well. I now get concert levels of body rocking bass and it sounds tight and tuneful left the bungs in. As well as dance I have a penchant for classical organ and these subs really get us back to performance sound quality with Messiaen and similar where the long pipes are played. Also good on the few BluRays weve run on that system through a projector its the one to use if we know the soundtrack is good. Inception was shockingly good and the first gunshot in Bruges woke up the neighbourhood well. All in all a good pair of powerful subs which Ive never needed to strain to achieve playback as good as or better than the studio intended.
With the purchase of (two) XTZ Sub 3x12s I finally attained the bass/sub-bass that I was seeking since starting this hobby. The sound was low visceral articulate and accurate. The sound is never muddy or fatiguing its just there with the proper force and tonality that you can feel as well as hear. Ive never enjoyed listening to music and movies as much as I do now. As an added bonus customer service is exemplary. I highly recommend this product.

Just awesome. I Was a Little bit afraid it was going to be slow but it responds very quick to both Music and Movies. Only problem I have is that I need to reinforce my windows Before they shatter..
Have been interested in subwoofers and speakers for more than 30 years. Many speakers and subs have been tested over the years Finally at black friday i ordered the 3x12. It replaced a Klipsch 15 and a Infinity Kappa sub (music). The upgrade is incredible. The 3x12 give superior quality bass both at low/volumes. Best subwoofer I ever had and heard. Only drawback is the size. Highly recommend it. Thanks XTZ !!
