Music Lovers Rejoice
Subwoofer manufacturers are always talking about how "explosive" their subwoofers are (frankly so do we), but there's more to home entertainment than rocket blasts and explosions—there is also music, be it in the movies you watch or the CDs you enjoy. And for music the quality of a subwoofer's performance is way more important than the quantity. The bass should be "tight," precise, and musical. Bass notes should have pitch, not just a dull thud or drone. Definitive Technology was started by and is run today by music fanatics and the very first thing we do to evaluate a subwoofer prototype design is to listen to music. If a subwoofer doesn't do an exemplary job with music reproduction, it's not a Definitive.
Features in the Service of Superior Performance
The most obvious departures from previous SuperCube models are the addition of a digital display (cleverly hidden under the grille cloth) and a wireless remote. They're much more than an aid for chronic couch potatoes; they're serious performance optimizing tools for perfectly blending the subwoofer to your system and room and correcting for differences in program material.
In an ideal audio system the subwoofer works "invisibly," simply adding deep, loud bass without calling attention to itself—blending seamlessly with the main speakers. The key to seamless main speaker/sub blending is finding the perfect crossover frequency, equalization and phase settings for your system and room. And the best place to make those "set and forget" adjustments is from your listening chair via a wireless remote. For everyday use the remote makes it easy to set just the right amount of bass output to compensate for program material differences. As you make settings adjustments, the hidden display light up to indicate the setting value, and then turns off a few seconds later. You'll get exactly the bass performance you want — effortlessly at the touch of a button.
Digital Tracking Amplifier for Clean High Output
The SC8000 features a designed-from-the-ground-up brawny Class HD digital tracking amplifier that is optimized for real world power demands to deliver low distortion and high output. As well as producing high continuous power to cleanly reproduce sustained bass, this all-new Definitive amp has a high crest factor to deliver considerably higher power during short, transient peaks such as bass drum kicks and on-screen artillery blasts. You'll enjoy high volume, high impact, and low distortion bass from your favorite action/adventure films and TV shows without sacrificing the smooth response and quick precision needed for music.
As well as being powerful, the new Definitive amps are environment-friendly. The amplifier goes into idle mode less than 30 minutes after the cessation of signal and draws a mere half Watt or less of current, meeting international standards for low energy consumption.
Computers in the Subwoofer Exert Precise Control
The SuperCube 8000 has an integrated 56 bit Digital Signal Processor (DSP)–in essence a mini computer–that extends and improves the bass response. Multi-band digital protection systems tightly monitor and control the woofer system to prevent distortion and woofer damage at ultra-high volume levels with a minimum of audible artifacts. In contrast to simpler one-band compression/limiting circuits used in competing subwoofer amp designs, the Definitive subs feature a Multiband Dynamic Range Optimizer (M-DRO) that divides the frequency range into multiple bands. If the DSP detects an overdrive condition in the upper bass range, it applies just the right amount of compression and to prevent distortion to just that range without compressing the low bass, thereby vastly reducing the audible compression artifacts. The bottom line is that SuperCube bass is always tight, highly detailed and distortion free.
Rock Solid Cabinets Ensure Pure Low Distortion Response
The cabinet of a loudspeaker plays a large part in its sonic performance. Resonance and vibration can add unwanted distortion as well as drain away important acoustical energy from the system. Definitive's subwoofer enclosures have been specifically engineered to be totally inert and vibration free, to ensure you of absolutely pure sonic reproduction. The front and rear panels are nearly 2-inches thick and the cabinet incorporates multiple internal braces to ensure total solidity. To top off the extraordinary performance, the SuperCube 8000 is finished in gorgeous piano-gloss black.
High-Definition Subwoofer Drivers Deliver Superior Detail and Lightning-Fast Transient Response
The powerful, high-definition drivers used in the new SuperCubes were specifically engineered for their task: to deliver rock-solid low distortion bass, reaching down to the lowest frequencies, with an outstanding quality of superior transient response ("tightness"). The special ultra-stiff cones are joined to specially formulated surrounds and long-throw voice coils and spiders. The incredibly rigid cast Aluminum baskets are engineered to hold the massive magnet structures and large voice coils in absolute alignment. The high temperature voice coils are made of aluminum wound with triple insulated ultra-pure copper wire and baked in epoxy for superior power handling and reliability.
The SuperCube 8000 features a new 11-inch (28cm) subwoofer driver pressure coupled to two 12-inch (30cm) Ultra Low Bass Radiators. The total piston area is greater than a 18-inch diameter woofer but with far greater speed, musicality and control than a single large diameter woofer could ever deliver—and it all fits in a compact enclosure. The SuperCube 8000 can fill the largest domestic spaces with loud, visceral, extended and musical bass yet it occupies only 1.8 square feet of floor space!

A Full Range of Inputs Facilitates Easy Hookup to Any System
The SuperCube 8000 can connect to any audio system via your choice of single cable LFE, stereo line level and speaker wire level inputs. Or you can choose to go wireless with the optional SCW-100 wireless connectivity kit for the ultimate in connection convenience.

" The SC8000 was able to pressurize the room"
Packaging- LAME. The sub weighs 72 pounds which is remarkable given it is only a 16" cube and only the top and bottom of the enclosure is solid. So Def Tec packages this $1500 (MSRP) sub in a single, somewhat thin box with only styrofoam protection on the top and bottom. Nothing on the sides. It's a miracle they make it without major damage. I find this cheap packaging unacceptable at what the sub costs.
I've watched Wrath of the Titans and The Hunger Games on Blu-Ray and The Dark Night via Vudu HDX. The HDX stream LFE channel was so hot I had to lower the sub volume by more than half. Nice to have a remote.
Room size is 13w X 14D x 9H and can be sealed via two doors in opposite corners. I listen with the room closed off.
The sub was placed in the front right corner, 10 feet from the MLP. Interestingly I get very even bass response across the 4 wide sofa. By ear I can find no hot spot or obvious nulls anywhere in the listening area. I thought I would have trouble given the room dimensions. Maybe the combination of dual passive radiators have some affect here.
Unfortunately I've never had a sub in this room before. My old sub died during the move. So I have nothing to compare to.
So- Wrath of the Titans, movie was awful but the sound was awesome. The SC8000 was able to pressurize the room to a level that was starting to make my ears uncomfortable. I don't know what frequency I can hear to anymore but I during the labyrinth scene and the ending scenes with Kronos I could feel pressure without hearing it. There was plenty of tactile feel through the sofa and body. Scenes where Kronos slammed his fist down and sent shock waves through the army where well represented in the room. Pretty good for a such a small non ported box.
Pretty much the same with the heavy LFE scenes in the Hunger Games, especially the forest fire. No complaints with this movie.
However, The Dark Night via Vudu HDX with the super hot LFE track sent the sub into "CLP" being displayed even after I lowered the sub volume by half of what it runs with Blu-Ray. I'm thinking that there was some pretty heavy sub 20hz stuff or really heavy 30-40hz stuff. It's weird because overall the room wasn't pressurized nor was it as loud as either of the other two movies.
I haven't listened to much music with it although what I have listened to sounded fine to me.
Based on the test tones I downloaded there is not much at all below 20hz, which I expected. When movie watching I certainly don't know if I'm missing anything.
Over all I'm happy with it. I like the size. The remote is handy. I use it fairly often. The EQ settings are pretty pointless IMO. I don't use them. I tried them and they all make the sub sound worse or just weird.
Given its size and features (perhaps some have a use for the EQ settings)it's a very good performer as long as your room isn't too large.
Definitive response: Hear you on the packagaing. We will watch freight damage reports carefully. For what it's worth we've been selling bigger, heavier subs with essentially the same packaging for years with minimal problems.
As far as Clipping or other performance issues, it might be a good idea to talk to our Customer Support people who really know their stuff and are happy to help people get better performance out of their Definitive gear. (800) 228-7148 M-F 9:30 - 6:00 EST.
I have been waiting for this sub for almost a month. I had a Supercube 2000 which sounded good but I wanted something to shake the house. Def Tech support did an excellent job recommending this one. I did a special order through Magnolia/Best buy. When i picked it up at the store I had an immediate huge smile on my face and happily laughed when I first saw the box. It was big. WOW! Magnolia guy seen the specs on this and asked me "do you plan on shaking the foundation and keeping your neighbors awake?" When I first plugged it in i immediately put in the movie Tron. This sub does shake the house. When using EQ1 this thing goes so deep it rattles your bones. But EQ1 isn't meant to be used with the volume up loud because it can damage it. Using EQ3 sounds excellent with movies and you can crank the sound up loud and it still shakes you and your house. This sub sounds way better than any Velodyne i have heard. Even better than any Martin Logan or REL that cost $4k. Do not use this for a small room. Nothing smaller than 14x14 because this thing can over power the room.(I tried this in my bedroom) I have it set up in my home theater room which is 22x16 and this compact sub fills the whole room, I haven't found any dead spots. Once I get some acoustic wall panels I bet it will sound even better. When I get my projector set up I might buy another to put diagonally behind. Trust me you don't need 2 of these but I want another just to say i have 2 in the same setup. So I have had this for about a week now and everything i play whether it's movies, music and even games this thing does not disappoint. I cranked it up on a movie and i had things falling off shelves on the other side of the house up on the main floor. BUY and you WON'T be disappointed. Thank you Def Tech this is exactly what i have been looking for in a home subwoofer.
