Ive bought two 8.17 subwoofers mainly for stereo. They acompany my Kef LS50 W Active speakers. So now I have a complete active full range stereo setup. These little subwoofers are wonderfull.. they are powerfull and go as deep as 29 Hz in my 45 square meters room. I use Roon DSP for room correction (measured with REW) and add a housecurve with the KEF DSP. Crossovers are set internal in the Kef DSP 80 hz for the Kef and 85 Hz for the 8.17 Now I have a powerfull clean and detailed bass and because the Kefs doesnt have to play the deepest bass they sound clean and fast in the midrange and highs. Thank you XTZ for these fantastic little subwoofers. Ill hope XTZ one day will do active dsp speakers too.. the 99.25 maybe

I run the sub with the 95.22 as a 5.1 system with a Denon AVR 1912. At first I was concerned that the 8.17 is too small and can never produce a decent bass. After installing I was really astonished. Not only audible but also palpable bass is generated in my 18sqm living room (with laminate floor). When fully turning up the volume the 8.17 reaches its limits and begins to roar so those who want a brutal and extremely loud subwoofer and do not live in a rented apartment should look for larger subwoofer. Conclusion: For me the Sub 8.17 was the perfect choice. With music and movies a precise and tactile bass is produced and the price is just great!

The 8.17 is a really great subwoofer for the price and size. I use it for my 16sqm living room and it creates exactly the bass that I want powerfull but still controlled. It fits perfectly to my bookshelf speakers! The only small thing I do not like is the white cover which makes the drivers shine through.
