Whether you're integrating into a home cinema or a stereo setup, the SUB 12.17 EDGE provides multiple tools to shape bass response. These include three factory-tuned EQ profiles, a fully adjustable parametric EQ, and a flexible port system. Together, they allow you to adapt the subwoofer’s performance to your room acoustics, speaker setup, and personal preference.
Multiple tuning options
EQ presets, PEQ, and port modes offer different paths to optimize for room and taste.
Designed for flexibility
Works equally well in small to large rooms and can be tailored to suit your priorities for music or film playback.
The onboard DSP includes three selectable EQ profiles to quickly adapt the subwoofer to your room or content. Each preset adjusts the system's frequency response and extension characteristics.
REF
Flat response for full-range extension and maximum fidelity.
EQ1
Slightly reduced low-end extension for tighter bass and boundary compensation.
EQ2
Boosted upper bass for more punch and energy in dynamic content.
The built-in PEQ lets you correct a room-induced peak or null with precision. It allows manual adjustment of frequency, Q (bandwidth), and gain to achieve a smoother in-room response.
Adjustable frequency range
Target a frequency between 30–120 Hz to correct the problem area.
±9 dB gain control
Boost or cut as needed to flatten the response curve.
Compatible with measurement tools
Use room measurement tools like REW or XTZ Room Analyzer II Pro to visualize your room’s acoustic response and guide your PEQ adjustments.
Port Tuning - High frequency
With no plugs in the ports the subwoofer will provide a “quick” and “punchy” bass character. It will produce increased output higher up in the frequency range.
Port Tuning - Mid. frequency
If the left port is blocked and the right port is open, this will provide a bass with an increased output in the mid-region.
Port Tuning - Low. frequency
If the right port is blocked and the left port is open, this will provide a deep bass with an increased output in the lower frequencies.
Both ports closed
With both ports blocked the sealed box will provide a dry and controlled bass character.
"Best in test - in mega subwoofer test
We have tested the 12.17 Edge before and it is interesting to see how it time and again can deliver such good bass sound and always at such an attractive price."
"Our warmest recommendations. It is only to surrender to XTZ SUB 12.17 Edge!
Its a very good subwoofer in every way and if you have 10000 SEK to spend it is this subwoofer you will spend your money on!"
"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"
"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"
"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"
"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"
"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"
"If you are searching for the best sound for your home cinema have an eye on this XTZ-combination - Highlight- Jochen Schmitt Heimkino-Magazin
+ First class finish
+ Outstanding sound
+ Excellent equipment"
"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"
"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"
