Definitive TechnologyDescend DN10 10" Subwoofer - Digitally Optimized for Movies and Music, New 3XR Architecture, 500W Peak Class D Amplifier & (2) Pressure-Coupled 10" Bass Radiators, Black

EDIT: May 10, 2025I added the large DN10 to the extra-small DN8, and it all worked as hoped for. I figured that mixing the DN10 with the DN8 would do no harm, and that's what happened. However, I do use Audyssey MultEQ XT32 for calibration, so that simplifies room calibration tremendously. I see that PolK and such are way more popular on Amazon, and subwoofers such as those are probably very good. But, weeks ago, after hearing the DN8 to replace the SVS SB12 NSD, I was sold on the Definitive Technology Descend subwoofer line. That's complete by adding the DN10 with the DN8. Bass is better than it has ever been and way more musical.One more thing, I use "Auralex Acoustics SubDude II isolation platform" for both subwoofers, I can only hope they are doing their jobs. LOLEDIT: MARCH 31, 2025Well, the SVS SB-12 works OK with the DN8, but they are not twins. A lot of the time the SVS "wakes up" boomy, but the DN8 deftly and seamlessly attacks the LFE [low-frequency-effects] as if the sub-bass were a part of the ELAC towers. As soon as I see Amazon put the DN8 on another good sale, I'm getting the second DN8 for my setup and putting the SVS someplace else. I will never buy SVS again.EDIT: NOVEMBER 26, 2024I still highly recommend the DN8. It works well across all genres and sounds great; plus it has a small footprint. If you have the space and don't worry about transferring sound to others disturbing them, then by all means go for the DN10, DN12, or DN15. You can always return for a refund in the Amazon return window for a full refund if not satisfied. But I don't think you will be returning these guys.CAVEAT: You must calibrate with an AVR room calibrator [Audyssey MultEQ XT32], or some calibration gadget, or you take an unnecessary risk to receive the full benefit of the Definitive Technology expertise.ORIGINAL REVIEW: NOVEMBER 02, 2024I think of Excellence Cubed when I listen to my setup now. Before installing the DN8, my system consisted of:1. Marantz SR6015 AVR2. Outlaw 5000 AMP3. LG OLED 65CX HDTV4. Apple TV 4K 2021. (Can hardly wait for the 2025 model)5. Sony UBP-X800 Blu-ray6. ELAC Uni-Fi 7.X.4: Fronts, Center, Surrounds, Surround Backs; and 4 Heights7. SVS SB12 NSD (which corresponded to SVS SB1000) for Left/Right channelsMy system was structured as listed above until this past October 2024, when one of the SVS subwoofers died, moreover after only seven years of service. In hindsight, it turns out to be a good thing, because I was able to audition the Descend DN8, which is excellent in every way compared to the SVS SB12.I figured after hearing the remarkable improvement presented by the DN8 that I would need another DN8 and get rid of the one remaining SVS, but after room-calibration with Audyssey MultEQ XT32, the SVS SB12 and DN8 behave like twins. 🤣 I can worry about what happens with the surviving SVS SB12 later.My room is 15’ W x 13’ D x 9’ H, and is now very nicely pressurized with the SVS SB12 and Descend DN8 working together. When I had both SVS subs installed, the SPL came nowhere close to what it is now. Sound Pressure Level is more important than many might know or understand. I live in an apartment, so I should never have the DN10 or higher. It doesn’t matter because the DN8 is just . . . excellent. I swear I can hear all kinds of bass notes never heard before. And, probably due to Audyssey calibration, the integration of the center, towers [front L/R; surround L/R], stand speakers [surround back L/R], heights, and subwoofers is flawless. I had calibrated the dual SVS subs with Audyssey as well.There is the saying that “a chain is no greater than its weakest link,” which applies to my system wherein the Descend DN8 has lifted all my equipment to a whole new level, and the Descend DN8 has opened up possibilities in the Marantz SR6015 that the SVS SB12 was not capable of.To clarify the "weakest link" statement: SVS SB12 may have held back my system before by just creating "boom," in everything, music, explosions, etc., now, the SB12 is on a whole new level of musicality and not the weakest link anymore because of exposure to the DN8.

Bought as a replacement for 20+year old definitive sub this was an eye and ear opening revelation. Construction is high quality and this weighty subwoofer looks sleek and refined in my space. Setup was straightforward with the included remote simplifying the process allowing you to get the settings dialed in from your listening position.The quality once setup is outstanding. I am using with older definitive tech mythos speakers and with both music and home theater use the bass blends perfectly, punchy and clean in the mid bass while digging deep with movie soundtracks. Although this is a 12 inch sub it sounds larger and retains an amazing clarity even as you lean in and push the volume to house shaking levels. Extremely pleased with this purchase and recommend without hesitation!

Important: this sub ships with sensitivity at -6db.Was excited to replace my old sub. Connected it and was underwhelmed- only in certain parts of the music I heard the deep lows.Come weekend- read the manual and tinkered with the settings. Set input sensitivity to 0 dB- my disappointment turned to delight. The sub begun to rock. High quality deep bass- not the boomy cheap sub sound but nice and deep.I'm glad I got the 12 inch. The 15 inch too large and the 10 inch would have to work real hard to keep up with my taste in sound. The 12 inch is quite huge and heavy. I like that it's heavy. Means it's well built and it's own weight will keep it from getting affected by vibrations.I keep display at off. Sound at deep as I only use it for music. Have it connected to my speaker out on the srereo amp ( sony ta-1es) for better sound integration. Not using line in.The remote is useful to tinker with settings. The remote build quality is surprisingly really cheap. Seems like a $2 item. Thankfully, after a couple of weeks- all the tinkering is done and then one really does not need the remote as such. All the same- dt should not have made it so low quality.Do I recommend the sub?- a really low 25hz - Yes!Ps- I bought a new power cable for the subwoofer. A monstrous thick 2nd hand PS Audio shielded power cable. Sub didn't get louder buy it certainly got cleaner and went down even lower. Upgrading the power cable added a new dimension to my sub. 6 months since I bought the sub- I'm very happy with it.
