Huge Bass From a Tiny Enclosure
If you want all the high impact bass excitement of the finest home theater audio systems without taking up a large amount of floor-space, then this is the subwoofer for you. The SuperCube III incorporates a 7-1/2 inch SuperCube® Technology woofer pressure coupled to two 7-1/2 inch Ultra Low Bass Radiators. The total piston area is greater than a 12-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 an impossibly tiny enclosure that is easy to tuck away out of sight. The SuperCube III can easily fill all but the largest domestic spaces with loud, visceral, extended and musical bass yet it occupies less than three-quarters of a square foot of floor space!

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 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 isn't a Definitive.
Massive Power
The SuperCube III is powered by a 650-watt class D amplifier. The result is astounding high-definition bass performance extending effortlessly down to 16 Hz. Slam, pace and rhythm are exemplary as is the ability to actually shake the walls. A complete complement of inputs and controls are included on this surprisingly compact and stylish cube. To top off the extraordinary performance, the SuperCube III is finished in gorgeous piano-gloss black.
High-Definition Drivers Deliver Superior Detail and Lightning-Fast Transient Response
The powerful, high-definition drivers used in all Definitive powered subwoofers 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 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 power handling in excess of 750 watts.
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 energy from the system. Definitive's subwoofers utilize monocoque cabinets, which have been specifically engineered to be totally inert and vibration free, to ensure you of absolutely pure sonic reproduction. Monocoque means that the cabinet is of a unitized construction where all panels are permanently joined together into one solid structure. The cabinet walls themselves are high-density medite fused together by space-age polymer adhesives. The front and rear panels are nearly 2-inches thick and the cabinets each incorporate multiple internal braces to ensure total solidity.
Adjustable Electronic Crossovers Assure a Perfect Match to Your System and Room
In a world class audio system you should not be able to perceive that the subwoofer and main speakers are separate entities—they should "blend" together perfectly to present a seamless sonic image of musical instruments and sound effects hovering in space in front of or around you. Getting such seamless blending is the "holy grail" of audiophiles and is rarely achieved in most systems. The key to success is "tweaking" the subwoofer's controls and it is here that the SuperCube III shines. The sophisticated low distortion electronic crossover incorporated in the SuperCube III is a masterpiece of design and execution. It contains a complete range of hookups, circuitry and features which allow it to be connected to and perfectly blended with any system and room.
A continuously adjustable low pass filter control allows you to choose a high frequency roll-off of from 40 to 150 Hz. Along with a continuously variable phase alignment control and a precision level control you have all the necessary tools at your disposal to achieve absolutely seamless blending between main speakers and subwoofer.
Easy Hookup to Any System
The SuperCube III has a complete range of inputs, outputs and features to allow easy and effective hookup to any system either singly or in a stereo pair. Both speaker level and low-level inputs are provided as well as a separate direct-in LFE low-level input (which bypasses the crossover network) which may be used by itself or in combination with left and right channel high- or low-level inputs for the ultimate in subwoofer flexibility and performance.
It all started when my Volkswagon-sized Boston Subwoofer blew a few months ago. I started auditioning subs until I heard the Supercube series. I couldn't believe my ears. Surely there was no way that a speaker that small (SupercubeIII) could produce the musicality and deep tight bass I'd been accustomed to hearing from much larger enclosures.
I'm into home theater, but more so into quality audio, so I was looking for more than just "thump-factor" for movie special effects. I was looking for solid, robust and honest reproduction as the artist intended.
To make a long story short, I sold all my Boston speakers, about $3,500. and 200#'s worth. I purchased the SupercubeIII, 4 Pro-Monitor 1000's and the Pro-Center 2000. I am in audio heaven. All my friends and yes, even my wife have commented on the incredible sound. I'm running a Denon 2808ci receiver (also new) and the match is perfect.
Your service techs have been great as they've helped me tweak my system to get the most out of it. I still can't believe the value and quality of these speakers, and for about $2,000.
Keep up the good work. I've told everybody who will listen about your products and will gladly do an a/b comparison with anything out there!
I'm one VERY happy customer in sunny Jacksonville, Florida!

"It really delivers"
All I can do is say I am very surprised. I knew what the SuperCube III was supposed to do. But I was doubtful that it would really live up to that. I keep this sub turned up about halfway or just barely over and it sounds about perfect watching movies. The bass is as tight as I've heard in this price range...
It really delivers. Even if you don't require a small sub for space this sub still performs as well, looks better, and takes up less space than most value priced 10 or 12 inch subs.
And to get an idea of the size if you haven't seen this in a store or dealer. You need to get out a ruler and see how big 10 inches is.
Also I am not using this with what most would call a high-end receiver. I have an Onkyo sr701, 4 Athena ws-100's and an Infinity Center. The bass strong when it suppose to be and is very tight. Not boomy.

"This subwoofer kicks serious butt..."
I purchased this subwoofer together with the studio monitor 450's, clr 2002, and a pair of studio monitor 800's as surrounds, which has turned out to be an incredible combination. Suffice it to say, if you are looking for a sub that can truly re-create the "thud" of T-rex's feet in Jurrasic Park, the seismic depth charges in U14 (submarine movie,) as well as the warmth, speed, and accuracy of tight jazz bass or the like, and all in a package that takes up no more than a 10 inch footprint, look no further, this is the one. This is a dense and physically solid little speaker, there is no internal vibration, nothing but clean, potent low level sound. Very easy using volume and phase control to blend with your mains. I set the crossoveron my receiver to 80hz, as the 450's handle base beautifully, and everything below goes the the supercube, which lives up to it's name. One thing I will recommend, is an Aurolex sound isolation platform, 50.00, which will keep this sub from rattling your furniture, which it is all to capable of doing if called on. This subwoofer kicks serious butt, and I am always amazed at how much power can come out of something so diminutive in size. Thanks again Definitive. Hillel Ulysses Gorelick

"thunderous!"
My Supercube III sub-woofer is the perfect compliment to my surround sound system. The bass is clean, sharp, deep and thunderous!

"great customer service."
I own two of these subs and was quite satisfied for 6 years. Then the gain on one sub quit working. The tech support was helpful on the diagnoses. A cost of $100.00 to repair. Then 3 months later the same thing happened to the second sub. Besides that the subs are tremendous. Clean, tight, powerful, and accurate bass that put subs costing twice as much to shame. Not to mention great customer service.

"Thank you Def Tech"
Simply addicted: I had my first taste of Def Tech while at a friends house, as an avid photographer I was there to help a friend with a picture problem and his 3 y/o son was watching "Up" Pixar. Holy fullness Batman was all that went through my head. I found myself so distracted by the great depth beckoning me from the room away. I had to take a moment to truly audition as to satisfy my enticement. I had no luck finding the Sub, I knew it had to be in the room. I was floored when my friend made me aware that the tiny, shiny, black, box behind the receiver next to the wall was the source of this melodious abyss-like splendor. He had a ProCinema 800 set-up with 3 ProCenter 1000's as L/R/C and use the 800's for 7.1. I now have an almost identical selection, with 3 ProCenter 2000's and 4 800's as 7.1 the SCIII wraps it all up tight and tidy. Thank you Def Tech keep it up!!!
