    • High quality lows.
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. ... show more

    • Amazing sound for a tiny little cube
Color: Black Style: DN8
I have had bigger subwoofers, but never had one that sounded as loud and clean as this one. I have all DT speakers, and the front three have powered subs. But, even with all that bass, this still adds some rumble to my setup. I can't image getting the bigger one, or having two, it would probably be too much. But, I have a nice sized room, and with the DT setup and this sub I can honestly say this setup sounds better than any theater I have been to in recent memory. The setup is very simple. One pre-amp coax from the receiver to the sub, then power. I set the filter and power to middle, and haven't touched it, it really just sounds amazing. You will not regret this purchase. You don't need to have all DT speakers, this would sound great against ANY setup. It is just amazing how much bass they can squeeze out of this. When I run the subwoofer sound check and turn up the volume it can make my house rumble (not literally). ... show more

    • Impressive performance!
Color: White Style: DN8
I had already purchased the vaunted SVS 3000 Micro sub a few months before pulling the trigger on the Def Tech Descend DN 8 so I really wasn't expecting much from this sub. Boy was I wrong! I have to say, the visceral power, more importantly, the quality of sound from the DN 8 was shocking! I had initially tried the SVS 3000 Micro in my home theater system but found I could never quite dial in the sound to my liking, even with the remarkable SVS app. It always seemed overly boomy and on the verge of bottoming out during loud action scenes. I eventually took it out of my HT system and added it to my bookshelf speakers for two channel music listening where it seems much better suited. When the DN8 arrived and I added it to my HT system and dialed it in with the help of my Sony STR-ZA5000ES receiver's "Advanced Digital Cinema Auto Calibration," the system came alive. Not only did the low end visceral power return, but I couldn't get over the quality of the base. I began dialing up music on YouTube to play through the system and the DN8 did an amazing job of demonstrating its finesse, speed and textured base notes. I never heard any of the muddy base notes I experienced with the SVS in the system, just clean, fast, punchy base! I have to say this Definitive Technology DN8 is tremendous value for the money. I can only imagine how the DN10 & 12 sound! For my smallish living room the DN8 is more than enough for me. Great job Definitive Tech! ... show more

    • Compact yet musically delivers. Nice settings. With direct speaker cable inputs.
Color: Black Style: DN8
I use this subwoofer to complement regular size high-end audio where speakers, Thiel CS 1.7 , have relatively limited representation of low frequency until 52Hz. The setting was easy but finding the best parameters requires manual discovery try and error for two speakers system. For surround system it would be much simple as this subwoofer has automatic feature. One of the reasons I got this subwoofer is that it has input of both LFE and standard speaker plug from amplifier. I connect the two sets of speaker cables from my mono amplifier Parasound JC1 to both Thiel CS1.7 and this subwoofer. JC1 has dual speaker output. It turned out that my environment worked best with 180 degrees of phase switch. This item has two phase settings, 0 as its default and 180 as another option. Other options include low pass filter, and in my case the lowest range fits best. Easy to change and to find the optimal point. Manual is detailed enough. A picture of manual is attached. Bass sound is concrete and relatively firm. It does not recede. Enough to enough bass structure to the extremely detailed and realistic sound stage from Thiel, making sonic stage even more colorful and vibrant. For the use cases like mine, I do believe this subwoofer works. If your audio room is large, consider a different model but for a small to mid size room with a need to add quality bass, this subwoofer is one of the most attractive choices. ... show more

    • This sub has little man syndrome
Color: White Style: DN8
This is a small sub with a big hit. Not sure what kind of witchcraft they use to muster so much bass from this little guy but i wouldn't want to meet him in a dark alley. Build quality is excellent and has all the necessary adjustments to tailor this to your system. If you want big sound but the wife wont sign off on a refrigerator in the corner then worry no more, this sub has you covered. ... show more
